{"title":"Magnetic \u0026 Electric Door Locks","description":"\u003cp\u003e\u003cstrong\u003eElectric door locks in Pakistan start at Rs 2,299 for a 60kg magnetic lock, Rs 2,999–12,499 for 180kg to 380kg maglocks, and Rs 2,899–12,500 for electric drop bolt locks. ZL mounting brackets are Rs 2,399–2,899.\u003c\/strong\u003e ZZ Marts stocks 13 magnetic and electric bolt locks for access control, with stores in Karachi and Lahore and installation available.\u003c\/p\u003e\u003ch2\u003eChoosing an electric lock\u003c\/h2\u003e\u003ch3\u003eMaglock or bolt lock is a door-type decision first\u003c\/h3\u003e\u003cp\u003eA magnetic lock clamps an armature plate with an electromagnet. Nothing is cut into the door, which makes it the obvious choice for glass and aluminium. An electric drop bolt throws a pin into the frame, which needs a hole but gives real mechanical resistance — the right answer for wooden and metal doors.\u003c\/p\u003e\u003ch3\u003eThen it is a fire-safety decision\u003c\/h3\u003e\u003cp\u003eA magnetic lock is fail-safe: cut the power and the door opens. That is exactly what you want on an escape route and exactly what you do not want on a store room during load-shedding. Drop bolts can be specified fail-secure and stay locked through a power cut. Decide which behaviour the door needs before you choose the technology.\u003c\/p\u003e\u003ch3\u003eHolding force: match the door, do not just buy the biggest\u003c\/h3\u003e\u003cp\u003e60kg suits a cabinet or a light internal door. 180kg is right for a standard office door. 280kg covers heavy glass and main entrances. 380kg is for wide, heavy or high-traffic doors people lean on. Over-specifying wastes money and draws more current; under-specifying means the door pops under a shoulder.\u003c\/p\u003e\u003ch3\u003eBudget for the bracket, it is not included\u003c\/h3\u003e\u003cp\u003eA frameless glass door or an inward-opening door needs a U or ZL bracket set at Rs 2,399–2,899 to hold the armature plate square. Ordering the lock without the bracket is the most common reason an installation stalls halfway.\u003c\/p\u003e\u003ch3\u003eFive-wire locks tell your system what the door is doing\u003c\/h3\u003e\u003cp\u003eThe 5-wire NO\/NC models add a status output, so the controller knows whether the door is actually secured rather than just whether it was told to lock. On any door that matters, that feedback is worth the small premium.\u003c\/p\u003e\u003ch3\u003eManual override on bolt locks\u003c\/h3\u003e\u003cp\u003eThe Rs 12,500 drop bolt with key cylinder can be released mechanically. On any door that could trap someone during a fault, that override is not optional.\u003c\/p\u003e\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\u003ch3\u003eWhat is the difference between a magnetic lock and an electric bolt lock?\u003c\/h3\u003e\u003cp\u003eA magnetic lock holds with an electromagnet against a steel plate and releases when power is lost. An electric bolt lock throws a pin into the frame, needs cutting into the door or frame, and can be specified to stay locked during a power cut.\u003c\/p\u003e\u003ch3\u003eWhat holding force do I need?\u003c\/h3\u003e\u003cp\u003e60kg for cabinets and light internal doors, 180kg for standard office doors, 280kg for heavy glass and main entrances, and 380kg for wide or high-traffic doors.\u003c\/p\u003e\u003ch3\u003eDo magnetic locks open during a power cut?\u003c\/h3\u003e\u003cp\u003eYes. That is by design and is why they suit fire escape routes. If the door must stay locked through an outage, use a fail-secure bolt lock or add a backup supply.\u003c\/p\u003e\u003ch3\u003eHow much does a magnetic lock cost in Pakistan?\u003c\/h3\u003e\u003cp\u003eA 60kg maglock is around Rs 2,299, 180kg Rs 2,999, 280kg Rs 3,499–4,899 and 380kg Rs 9,899–12,499 depending on whether it has NO\/NC status output.\u003c\/p\u003e\u003ch3\u003eDo I need a ZL bracket?\u003c\/h3\u003e\u003cp\u003eYou need one if the door is frameless glass, opens inward, or has no flat surface for the armature plate. U and ZL bracket sets cost Rs 2,399–2,899 and are ordered separately.\u003c\/p\u003e\u003ch3\u003eWhat power supply do these locks need?\u003c\/h3\u003e\u003cp\u003eMost run on 12V DC. Add up the lock, reader and any sensors, then choose a supply with headroom and battery backup — essential in Pakistan if the door must stay controlled through load-shedding.\u003c\/p\u003e","products":[{"product_id":"180kg-zl-bracket-for-magnetic-lock-z-l-mounting-bracket-set","title":"180KG ZL Bracket for Magnetic Lock – Z \u0026 L Mounting Bracket Set","description":"\u003ch2 data-start=\"75\" data-end=\"92\"\u003eKey Features\u003c\/h2\u003e\r\\n\u003cp data-start=\"94\" data-end=\"277\"\u003e• Designed for 180KG Magnetic Locks\u003cbr data-start=\"129\" data-end=\"132\"\u003e• Complete Z \u0026amp; L Bracket Set\u003cbr data-start=\"160\" data-end=\"163\"\u003e• High-Strength Aluminum Alloy\u003cbr data-start=\"193\" data-end=\"196\"\u003e• Secure \u0026amp; Stable Mounting\u003cbr data-start=\"222\" data-end=\"225\"\u003e• Corrosion-Resistant Finish\u003cbr data-start=\"253\" data-end=\"256\"\u003e• Easy Installation\u003c\/p\u003e\n\n\u003cp data-start=\"311\" data-end=\"477\"\u003eThe \u003cstrong data-start=\"315\" data-end=\"353\"\u003e180KG ZL Bracket for Magnetic Lock\u003c\/strong\u003e is a complete Z \u0026amp; L mounting bracket set designed for installing 180KG electromagnetic (mag) locks on inward opening doors.\u003c\/p\u003e\r\\n\u003cp data-start=\"479\" data-end=\"731\"\u003eThis bracket combination allows proper alignment of both the magnetic lock and armature plate when direct mounting is not suitable.

The Z bracket carries the armature plate on the door leaf and projects it forward so the two faces meet flush when the door closes.

If your door is frameless glass with no frame to screw into, you need a U bracket instead, which clamps the glass. Tell us the door type before ordering.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eAlignment decides whether the lock holds properly.\u003c\/strong\u003e The magnet face and armature plate must sit flush and parallel when the door is closed. Even a small air gap from a slightly misaligned bracket reduces holding force noticeably, and on a lighter 180kg lock there is less margin to absorb that loss. Fit carefully, close the door, and check the faces meet cleanly across the full surface before finishing the job.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eDo not bolt the armature plate solid.\u003c\/strong\u003e The plate is designed to float slightly so it can self align against the magnet as the door closes.

Where the door is light, this rating does the job properly and costs less than the heavier locks people often buy by default.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eWhy buying more holding force is not automatically better.\u003c\/strong\u003e This is worth stating plainly because it saves you money. A magnetic lock is only as strong as what it is bolted to. Fit a 380kg lock to a slim glass partition door and the glass, the frame, or the bracket will give way long before the magnet releases. You have paid for holding force the door can never make use of. Match the lock to the door and you get the same practical security for less.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eWhere 180kg is genuinely not enough.\u003c\/strong\u003e Being equally honest in the other direction: do not fit this to a main building entrance, a heavy timber door, or any door likely to be pushed or pulled hard. Those need 280kg or 380kg. If the door is the primary thing standing between the outside and your stock, cash, or equipment, buy the heavier rating. Tell us what the door protects and we will say which is appropriate.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eLower current draw, which matters across several doors.\u003c\/strong\u003e A magnetic lock draws power continuously the whole time the door is locked. A lighter lock draws less. On a single door this hardly matters, but across four or six internal doors on one power supply the difference is real, and it can be the reason a supply copes rather than causing intermittent faults. For multi door internal installations, specifying the correct lighter rating on light doors is both cheaper to buy and easier to power.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eGlass partition doors and the bracket question.\u003c\/strong\u003e A great many 180kg locks go onto frameless or semi frameless glass, which needs a U bracket clamping the glass rather than screwing into a frame. Glass thickness determines which bracket fits, so confirm it before ordering. This is the most common reason a glass door installation stalls. Send us a photograph of the door edge and tell us the glass thickness and we will supply the matching bracket with the lock.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eFail safe operation and load shedding.\u003c\/strong\u003e Like all magnetic locks, this releases the moment power is cut. On internal doors that is usually convenient rather than a concern, but be deliberate about it. If an internal room must stay secure through an outage, either plan a backup supply or use an electric bolt lock, which is fail secure and stays locked without power. We stock both and will tell you which suits the room.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eNC wiring for the exit device.\u003c\/strong\u003e Because the lock releases when the circuit opens, exit buttons wire as normally closed. Getting this backwards gives you a door that never locks or never releases, and it is the most common wiring error on maglock installations regardless of rating.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eEscape routes still apply indoors.\u003c\/strong\u003e Even internal doors can sit on an escape route. Where they do, the lock should be wired so a fire alarm activation cuts power and releases it independently of the access control system, and an emergency break glass release should be fitted alongside. Do not assume this only matters on external doors.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eMaintenance.\u003c\/strong\u003e Keep the magnet face and armature plate clean, since dust or grit between the surfaces reduces holding force, and on a lighter lock you have less margin to spare. Check occasionally that the armature plate is still flush and tight.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eWill 180kg hold my glass door?\u003c\/strong\u003e For a typical internal glass partition, yes. Tell us the door size, weight, and glass thickness and we will confirm rather than have you guess.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eCan I use it on a main entrance?\u003c\/strong\u003e We would not recommend it. Use 280kg or 380kg where the door is a primary barrier.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eWhat bracket do I need?\u003c\/strong\u003e Depends on the door. Frameless glass needs a U bracket, inward opening framed doors usually an L bracket. Send a photograph and we will confirm.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eWhat happens in a power cut?\u003c\/strong\u003e The door releases, since maglocks are fail safe.

Office entrances, shop doors, glass and aluminium framed commercial doors, clinic doors, and internal secure rooms are all well served by this rating. It is strong enough for real commercial use without paying for force the door itself could never justify.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eHow to choose between 180kg, 280kg and 380kg.\u003c\/strong\u003e Think about what the door is protecting and how it would be attacked. A light internal partition or a cupboard door is fine on 180kg. A main building entrance, a heavy timber door, or anything likely to be pushed hard deserves 380kg. Everything in between, which is most commercial doors, sits comfortably here. The mistake we see most often is buying the largest rating on the assumption that stronger is always better, when in practice the door leaf or frame will fail long before a correctly specified magnet does.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eDouble doors need one lock per leaf.\u003c\/strong\u003e This genuinely catches people out and costs them a return visit. Two doors meeting in the middle cannot be secured by a single larger magnet, because each leaf moves independently and each needs its own lock and armature plate. When specifying a double entrance, budget for two locks, two brackets, and a power supply rated to run both continuously.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eBrackets, and why installations stall without them.\u003c\/strong\u003e The lock body mounts to the frame and the armature plate to the door, but which bracket you need depends entirely on the door. Inward opening doors normally take an L bracket. Frameless glass doors need a U bracket that clamps the glass. Outward opening doors and narrow aluminium sections each need their own fitting. Ordering a maglock without the matching bracket is the most common reason an electrician arrives and cannot finish the job. Send us a photograph of the door and we will supply the correct bracket with the lock.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eFail safe operation and load shedding.\u003c\/strong\u003e Magnetic locks release the instant power is cut. That behaviour is exactly why they suit escape routes, and exactly why load shedding will open the door. Decide deliberately at specification stage whether this door must stay secure through an outage. If it must, plan a backup supply or UPS. If it is an escape route, the fail safe behaviour is the point rather than a drawback.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eContinuous current draw matters when you have several doors.\u003c\/strong\u003e A magnetic lock consumes power for the entire time the door is locked, unlike a bolt lock which draws only when operating. One door is straightforward. Four doors on one supply is where people run into trouble, because an undersized supply produces intermittent, difficult to diagnose faults. Tell us how many doors you are running and we will size the supply correctly.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eNC wiring for exit buttons.\u003c\/strong\u003e Because the lock releases when the circuit breaks, exit buttons and release devices wire as normally closed. Reversing this produces a door that either never locks or never releases, and it remains the most frequent wiring error on maglock jobs. Confirm contact types before wiring, particularly when a keypad, exit button, and break glass release all share one door.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eFire alarm interfacing on escape routes.\u003c\/strong\u003e Where the door is on an escape route, wire the lock so that a fire alarm activation cuts power and releases it independently of the access control system. This is a basic life safety expectation and is routinely missed when fire and access systems are fitted by different contractors at different times. We supply both and can make sure they work together.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eKeeping the holding force you paid for.\u003c\/strong\u003e Wipe the magnet face and the armature plate clean periodically. Dust, grit, and paint overspray between the two surfaces reduce holding force noticeably, and this is the usual reason a lock starts feeling weaker than its rating. Check the armature plate is still flush and has not worked loose over time.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eIs 280kg enough for a main entrance?\u003c\/strong\u003e For many commercial entrances yes, but tell us the door material and width and we will say honestly whether 380kg would be the better choice for your specific door.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eWill it work on a glass door?\u003c\/strong\u003e Yes, with the correct U bracket or patch fitting.

Power controls whether the bolt is thrown or withdrawn, and your access control system decides when. It is the straightforward, economical choice for wooden, metal, and framed doors where you want genuine mechanical strength rather than magnetic holding.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eBolt or magnet, and how to decide.\u003c\/strong\u003e A magnetic lock holds the door with an electromagnet and releases the moment power is lost. A drop bolt physically pins the door and, in standard form, stays locked without power. The bolt resists forcing better because an intruder is working against steel rather than magnetic attraction. The magnet is safer on escape routes because nobody can be trapped. Decide by what the door is for: a store room, server room, or back office suits a bolt; a main exit route suits a magnet, or a bolt with an emergency release fitted alongside.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eFail secure, and what load shedding means for you.\u003c\/strong\u003e Because this stays locked when power is absent, your door remains secure right through an outage. That is exactly what you want overnight on a store room or godown. The consequence is equally important: without power, and without a manual override, nobody opens that door until the electricity returns. If the room needs to be accessible at all times, either fit the key cylinder version, add a backup supply, or install a break glass release. Make this decision before installation rather than discovering it during an outage.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eWhere it fits well.\u003c\/strong\u003e Wooden and metal framed doors, narrow doors where a large magnetic lock plate will not sit properly, office doors, store rooms, godowns, server rooms, and internal secure areas. Drop bolts need far less mounting surface than maglocks, which is often the deciding factor on slim door sections.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eSet the timer delay generously.\u003c\/strong\u003e Most drop bolts offer an adjustable delay before the bolt drops, commonly a few seconds. This exists so the door can close and settle before the bolt tries to engage. Set too short, the bolt fires while the door is still moving and either jams against the plate or misses the hole. A very large share of complaints that a bolt lock is faulty are simply a delay set too tight. Give it time and the lock behaves properly.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eAlignment matters far more than with a magnet.\u003c\/strong\u003e A magnetic lock tolerates small variation because it holds by surface contact. A bolt must physically drop into a hole. Fit the receiving plate so the bolt lands centred rather than at the edge, and remember that doors settle on their hinges and frames move with heat and humidity through the Pakistani year. A lock fitted with no tolerance in spring may bind by peak summer. When a bolt starts grinding or failing to throw, check alignment before assuming the lock has failed.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eWhat the complete installation needs.\u003c\/strong\u003e The bolt is one component. A working door also requires a controller such as an access keypad or card reader, an exit button on the inside so people can leave, a power supply rated for the lock, and mounting hardware suited to your door. Buying these as a matched set avoids the common situation of an electrician on site discovering a part is missing. We can quote the full kit.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eCurrent draw compared with a maglock.\u003c\/strong\u003e A drop bolt draws current only while operating, not continuously, unlike a magnetic lock which consumes power the entire time the door is locked. Across several doors this makes a meaningful difference to power supply sizing and running cost, and it is a practical argument for bolts on multi door installations.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eCabling and security.\u003c\/strong\u003e Run cable in conduit and keep it inside the secure side of the door. An accessible lock cable is an obvious weak point, since cutting it on a fail secure bolt will not open the door but does disable your control over it.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eDo I need the version with a key cylinder?\u003c\/strong\u003e If being locked out during a power cut would cause a real problem, yes. Our key cylinder version lets you withdraw the bolt mechanically regardless of power.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eIs it suitable for a fire exit?\u003c\/strong\u003e Not on its own.

The bolt still drives down into a receiving plate, giving the same mechanical security, but with a mounting arrangement that fits where a standard bolt will not.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eWhen you need this rather than a standard drop bolt.\u003c\/strong\u003e The deciding factor is nearly always available depth. Narrow aluminium sections, slim door frames, and doors where the top rail is shallow simply do not have room for a fully housed bolt body. Rather than compromising the fitting or abandoning the bolt approach, an open frame version mounts in the space you actually have. If a standard bolt looked like it would not fit your door, this is usually the answer.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eFail secure operation and load shedding.\u003c\/strong\u003e Like other drop bolts, this stays locked when power is removed, keeping the door secure through outages.

A bolt physically pins the door and resists forcing better, which suits secure rooms. Bolts also need much less mounting surface, which is exactly why they win on narrow and slim doors. Tell us how the door is used and we will recommend rather than default to whichever is dearer.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eTimer delay, set it generously.\u003c\/strong\u003e The adjustable delay before the bolt drops exists so the door can close and settle first. Too short, and the bolt fires while the door is still swinging, jamming against the plate or missing the hole entirely. This single setting accounts for most complaints that a bolt lock is defective when the lock is working perfectly well.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eAlignment is critical on an open frame mount.\u003c\/strong\u003e A bolt must physically enter a hole, and an open frame design gives you slightly less inherent guidance than a fully housed unit, so careful alignment matters even more. Fit the receiving plate so the bolt lands centred rather than at the edge of the opening. Doors settle on their hinges over time and frames move noticeably with heat and humidity through the year, so leave tolerance and re-check a few weeks after installation.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eLower power draw than a maglock.\u003c\/strong\u003e A drop bolt only draws current while operating rather than continuously, unlike a magnetic lock which consumes power the whole time the door is locked.

It is designed for frameless and semi frameless glass, which is the most common commercial door type on Pakistani shopfronts, showrooms, and office receptions.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eDrop bolt or magnetic lock, the decision that matters most.\u003c\/strong\u003e This is the question worth settling before you order anything. A magnetic lock holds the door with an electromagnet and releases the instant power is lost, which makes it the safer choice on escape routes. A drop bolt physically pins the door with a steel bolt and, in its standard form, stays locked when power fails. That makes it the stronger option against forcing, and the wrong option for a door people must escape through unless you fit an emergency release alongside. Tell us what the door is used for and we will say honestly which you should buy.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eWhy glass doors often suit a bolt rather than a magnet.\u003c\/strong\u003e A magnetic lock needs enough flat surface to mount a substantial plate. Narrow glass door rails and slim aluminium top sections frequently do not offer it. A drop bolt needs far less mounting area, which is why it is so often the practical answer on frameless glass and narrow framed shopfront doors where a maglock simply will not fit neatly.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eFail secure behaviour and load shedding.\u003c\/strong\u003e Because a standard drop bolt stays locked without power, load shedding will not release your door, which is exactly what you want for a shop secured overnight. The flip side matters just as much: if this is your only exit and power is out, nobody gets through it without a manual override or an emergency break glass release. For any door on an escape route, plan that release at specification stage rather than discovering the problem later.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eThe timer delay, and why bolts get blamed unfairly.\u003c\/strong\u003e Most drop bolts include an adjustable delay of a few seconds before the bolt drops. That delay exists so the door has time to close fully and settle before the bolt tries to engage. Without it, the bolt fires while the door is still swinging and either jams against the receiving plate or misses the hole entirely. A very large share of complaints that a drop bolt is faulty turn out to be a delay set too short. Set it generously and the lock behaves.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eAlignment is everything with a bolt lock.\u003c\/strong\u003e Unlike a magnet, which tolerates small variations, a bolt must physically enter a hole. Fit the receiving plate so the bolt lands centred in its hole, not at the edge. Glass doors swing freely and settle over time, and temperature swings across the Pakistani year move door frames noticeably. A lock installed with no tolerance in spring will start grinding or failing to throw by peak summer. If a bolt starts binding, check alignment before assuming the lock has failed.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eMounting on glass.\u003c\/strong\u003e Frameless glass needs a U bracket or patch fitting to carry the lock, since you cannot drill toughened glass on site. Glass thickness determines which fitting suits, so measure it or send us a photograph of the door edge before ordering. This is the most common reason a glass door installation stalls partway through.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eWhat else the installation needs.\u003c\/strong\u003e The bolt is one component. A working door also needs a controller such as an access keypad or card reader, an exit button on the inside, a power supply rated for the lock, and the correct mounting fitting for your glass. Buying these as a matched set avoids the very common situation of an electrician arriving to find one part missing. We can supply the complete kit.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eDo I need an emergency release?\u003c\/strong\u003e If the door is on an escape route, yes. Ask us about break glass releases and manual override versions.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eWill it fit my glass door?\u003c\/strong\u003e Send us a photograph of the door and its glass thickness and we will confirm the lock and fitting before you order.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eWhat happens in a power cut?\u003c\/strong\u003e A standard drop bolt stays locked.

It holds the door while powered and releases the moment power is cut. If you want maximum holding force on a main entrance without paying for status monitoring you will never use, this is the version to buy.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eHow this differs from our five wire model.\u003c\/strong\u003e Both deliver the same 380kg holding force and both fail safe. The five wire version adds a status output so your controller knows whether the lock is genuinely engaged, which suits server rooms, cash offices, and anywhere you need proof the door locked. This standard version does the locking job identically but reports nothing back. For the majority of doors, including most main entrances, shop doors, and office entrances, that feedback is unnecessary and the simpler lock is the sensible purchase.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eWhere 380kg is the right rating.\u003c\/strong\u003e Main building entrances, heavy timber doors, double doors where each leaf carries a lock, and any door likely to be pushed or pulled hard. If the door is your primary physical barrier rather than an internal divider, this rating earns its place. For internal office doors, glass partitions, and low traffic rooms, our 180kg and 280kg locks are more appropriate and cost less.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eDouble doors need one lock per leaf.\u003c\/strong\u003e This catches people out regularly. Two doors meeting in the middle cannot be secured by a single larger magnet; each leaf needs its own lock and armature plate, because each moves independently. Budget for two locks and a power supply rated for both when specifying a double entrance.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eFail safe behaviour and load shedding.\u003c\/strong\u003e Cutting power releases the lock instantly, which is exactly what makes maglocks appropriate for escape routes and exactly why load shedding will open the door. Decide at specification stage whether the door must stay secure through an outage. If it must, budget for a backup supply or UPS. If it is an escape route, the fail safe behaviour is the feature rather than the problem.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eBrackets decide whether installation goes smoothly.\u003c\/strong\u003e The lock mounts to the frame and the armature plate to the door, but the fitting depends on your door type. Inward opening doors generally need an L bracket, frameless glass needs a U bracket clamping the glass, and outward opening or narrow aluminium doors each need specific fittings. More installations stall over a missing bracket than over anything else. Send us a photograph of the door and frame and we will supply the correct bracket alongside the lock.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eContinuous current draw.\u003c\/strong\u003e A magnetic lock consumes power the entire time the door is locked, unlike a bolt lock which draws only when operating. Size the power supply for that continuous load, and remember the figures multiply across several doors. Undersized supplies cause intermittent, hard to trace faults.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eWiring the exit button as NC.\u003c\/strong\u003e Since the lock releases when the circuit opens, exit buttons and release devices are wired normally closed. Reversing this gives a door that never locks or never releases, and it is the most common wiring mistake on maglock installations. Confirm contact types before wiring, especially when a keypad, exit button, and break glass release all share one door.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eFire alarm connection on escape routes.\u003c\/strong\u003e Where the door forms part of an escape route, wire the lock so a fire alarm activation cuts power and releases it independently of the access control system. This is a basic safety requirement and is frequently missed when fire and access systems are installed separately. We supply both and can ensure they interface correctly.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eKeeping it working.\u003c\/strong\u003e Wipe the magnet face and armature plate clean periodically. Dust, grit, or paint between the surfaces reduces holding force more than people expect. Check the armature plate remains flush and tight, since a loose plate is the usual cause of a lock that feels weaker than its rating.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eShould I buy this or the five wire version?\u003c\/strong\u003e Buy this one unless you specifically need lock status feedback to a controller. Most doors do not.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eIs 380kg too much for my door?\u003c\/strong\u003e Possibly.

This version adds a status output, meaning the lock reports whether it is actually magnetised and holding rather than the system assuming it is. That matters on doors that genuinely need to stay secure: your access control panel can detect a door that failed to lock and alert you, instead of leaving it open silently overnight.

That makes it the correct choice for escape routes, because nobody can be trapped by it. It also means load shedding will open the door. If the door must stay secure through outages, plan a backup supply or UPS at specification stage rather than discovering the behaviour afterwards. Every maglock installation in Pakistan needs this decision made deliberately.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eBrackets are not optional, and are the most common ordering mistake.\u003c\/strong\u003e The lock body mounts to the frame and the armature plate to the door, but how they mount depends entirely on your door. An inward opening door normally needs an L bracket. A frameless glass door needs a U bracket that clamps the glass. Outward opening doors, narrow aluminium sections, and double doors each need their own fitting. Ordering a maglock without the matching bracket is the single most common reason an installation stalls halfway through the day. Send us a photograph of your door and we will supply the right bracket with the lock.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003ePower supply sizing.\u003c\/strong\u003e Unlike a bolt lock, which only draws current when operating, a magnetic lock draws continuously for as long as the door is locked. Your power supply must be rated for that continuous load, and across several doors the figures add up quickly. An undersized supply produces intermittent faults that are genuinely difficult to diagnose after the fact.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eNC wiring and the exit button.\u003c\/strong\u003e Because the lock releases when the circuit breaks, exit buttons and release devices are wired as normally closed. Getting this backwards produces a door that either never locks or never releases, and it is the most frequent wiring error on maglock jobs. Confirm contact types before wiring, particularly when combining a keypad, an exit button, and a break glass unit on the same door.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eFire alarm interfacing.\u003c\/strong\u003e On escape routes the maglock should be wired so that a fire alarm activation cuts power and releases the door independently of the access control system. This is a basic life safety expectation rather than a refinement, and it is regularly missed when the fire panel and the access control are installed by different contractors at different times. We supply both, so we can make sure the two work together.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eMaintenance that actually matters.\u003c\/strong\u003e Keep the magnet face and the armature plate clean. Anything between the two surfaces, whether dust, grit, or paint overspray, reduces holding force noticeably. Check periodically that the armature plate still sits flush and has not worked loose, since a slightly loose plate is the usual reason a lock feels weaker than its rating suggests.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eWhich holding force do I need?\u003c\/strong\u003e Tell us the door material, width, and whether it is internal or a main entrance, and we will recommend rather than upsell.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eWill it work on a glass door?\u003c\/strong\u003e Yes, with the correct U bracket or patch fitting.

For a fail secure bolt in a country with routine load shedding, that override is not a luxury feature. It is often the difference between a workable installation and a door nobody can open.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eWhy the key cylinder matters more here than elsewhere.\u003c\/strong\u003e A standard drop bolt stays locked when power fails. That is excellent for security and a genuine problem the first time an outage coincides with someone needing to get through the door. Without an override, your options are a backup power supply or waiting for the electricity to return. The key cylinder removes that dependency entirely, which is why we recommend this version for any door where being locked out would matter.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eWhere this version earns its cost.\u003c\/strong\u003e Shop shutters and side doors, store rooms holding stock you may need at short notice, offices where staff arrive before the generator is running, godowns, and any door that is the only practical route into a space. It is also the sensible choice where the door is used by people who would have no way of resolving a power related lockout themselves.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eDrop bolt or magnetic lock.\u003c\/strong\u003e A magnetic lock releases the moment power is lost, making it appropriate for escape routes but useless for keeping a door secure through load shedding. A drop bolt physically pins the door with a steel bolt and stays locked without power, which is stronger against forcing. This version adds the key override so you retain access without giving up that security. Tell us how the door is used and we will recommend honestly between the two.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eKey management, which people underestimate.\u003c\/strong\u003e The override key is now part of your security. Keep it somewhere accessible but not beside the door it opens, and decide deliberately who holds a copy. A key hanging on a hook next to the lock defeats the purpose of having a lock at all. For business premises, keep a record of who has been issued one.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eTimer delay, and the fault that is not a fault.\u003c\/strong\u003e Drop bolts include an adjustable delay before the bolt drops, giving the door time to close fully and settle before the bolt engages. Set too short, the bolt fires while the door is still swinging and jams against the plate or misses the hole. A large share of complaints that a bolt lock is defective turn out to be a delay set too tight. Set it generously and the lock behaves properly.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eAlignment matters more than with a magnet.\u003c\/strong\u003e A magnetic lock tolerates small variation because it holds by contact. A bolt must physically enter a hole. Fit the receiving plate so the bolt lands centred rather than at the edge of the opening, and allow for the fact that doors settle on their hinges and frames move with heat and humidity through the Pakistani year. A bolt that starts grinding or failing to throw is nearly always an alignment issue, not a failed lock.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eWhat the complete installation needs.\u003c\/strong\u003e The bolt is one part. You also need a controller such as a keypad or card reader, an exit button inside, a power supply rated for the lock, and mounting brackets suited to your door. Glass doors need a U bracket or patch fitting. Ordering these together avoids the familiar situation of an electrician on site with a missing component.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eIs this suitable for a fire exit?\u003c\/strong\u003e A fail secure bolt on an escape route needs an emergency break glass release in addition to the key override, since occupants cannot be expected to find a key during an evacuation. Tell us if the door is on an escape route and we will specify it properly.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eCan I open it from outside with the key?\u003c\/strong\u003e The cylinder allows mechanical withdrawal of the bolt.

For doors where you need certainty rather than hope, that feedback is the reason to choose this version.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eWhat the status output genuinely buys you.\u003c\/strong\u003e A basic two wire bolt receives a signal to lock and that is the end of the conversation. If the bolt failed to enter its hole because the door was obstructed, misaligned, or not fully closed, nothing tells you. The door sits apparently secured and actually open, often overnight. With a status output, your access control panel knows the bolt did not engage and can raise an alert or log the event. On a server room, a cash office, a pharmacy store, or a stock room, that difference matters considerably.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eNO and NC outputs, and why both are supplied.\u003c\/strong\u003e The five wires give a common plus both a normally open and a normally closed contact. Which you use depends on what is receiving the signal. Access control panels and alarm inputs differ in what they expect, and having both available means the lock suits either without needing a relay in between. If you only need a simple lock function, use the power pair and leave the status cores unconnected and insulated.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eFail secure operation and load shedding.\u003c\/strong\u003e Like other drop bolts, this stays locked when power is removed, which keeps the door secure through an outage. That is exactly right for a secure room overnight and a genuine consideration if the room must remain accessible. Without power and without a manual override, the door stays shut until supply returns. Decide this at specification stage: fit our key cylinder version, add a backup supply, or install an emergency break glass release if the door is on an escape route.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eBolt or magnetic lock for this kind of door.\u003c\/strong\u003e A magnet releases the instant power fails, suiting escape routes. A bolt physically pins the door and resists forcing far better, suiting secure rooms. Bolts also need much less mounting surface, which matters on narrow doors. Given this version is bought specifically for status monitoring, it usually goes on doors where security matters more than egress, which is where a bolt belongs.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eSet the timer delay generously.\u003c\/strong\u003e The adjustable delay before the bolt drops lets the door close and settle before the bolt engages. Set too short, the bolt fires while the door is still swinging and jams or misses. Ironically, this is also the fault a status output will faithfully report, so setting the delay properly saves you from chasing alerts that reflect a setting rather than a problem.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eAlignment, and why status output makes it easier to manage.\u003c\/strong\u003e A bolt must physically drop into a hole, and doors settle on their hinges while frames move with heat and humidity through the Pakistani year. The advantage here is that misalignment shows up in the logs as failed locking events rather than as a silent problem discovered weeks later. Fit the receiving plate so the bolt lands centred, and treat repeated status failures as a prompt to re-check alignment.\u003c\/p\u003e\r\\n\u003cp\u003e\u003cstrong\u003eWiring the extra cores.\u003c\/strong\u003e Label all five wires at both ends. A three or five wire lock is dramatically easier to maintain when whoever comes next can see which core is common, which is NO, and which is NC, rather than working it out with a meter.
