Carbon Monoxide Detector Price in Pakistan 2026: Heater Safety Guide
Quick answer: At ZZ Marts, a carbon monoxide detector costs Rs 5,799: the CO + Smoke Dual Sensor Alarm detects both carbon monoxide and smoke, shows the CO level on an LCD screen and runs on AA batteries, so it keeps working through load-shedding (price checked 3 November 2026). A gas leak detector does not detect carbon monoxide. For leaking Sui gas or LPG you need a separate gas detector: Rs 5,299 for the LCD gas leak detector or Rs 8,500 for the gas leak detector with automatic shut-off valve.
What carbon monoxide is, and why winter is the risk
Carbon monoxide (CO) is a poisonous gas with no colour and no smell. It is made when gas, wood, coal or kerosene burns without enough fresh air. In Pakistani homes the usual sources are a gas heater or angeethi running in a closed room, a geyser with a blocked flue, and a generator running indoors or near a window.
Early signs are headache, dizziness, nausea and unusual tiredness, which are easy to mistake for flu. People who are asleep may not notice anything at all. That is why a CO alarm belongs in the rooms where heaters run at night.
Carbon monoxide or gas leak: which detector do you need?
| Carbon monoxide (CO) | Gas leak (Sui gas or LPG) | |
|---|---|---|
| What it is | Poisonous gas made when fuel burns without enough air | Unburnt fuel gas escaping from a pipe, tap, heater or cylinder |
| Main danger | Poisoning, often while asleep | Explosion or fire, and suffocation in a closed room |
| Typical cause | Heater or angeethi in a closed room; blocked geyser flue | Heater tap left open when supply stops and restarts; cracked pipe; cylinder regulator leak |
| Detector | CO + Smoke Dual Sensor Alarm (Rs 5,799) | LCD gas leak detector (Rs 5,299) or shut-off valve kit (Rs 8,500) |
Most homes that use gas heaters need both: a CO alarm where the heater burns, and a gas detector where the gas could leak.

Example: protecting a home with gas heaters
| Setup | What you buy | Total (PKR) |
|---|---|---|
| Two heater rooms + Sui gas kitchen | 2 × CO + Smoke alarm (Rs 5,799 each) + LCD gas leak detector (Rs 5,299) | 16,897 |
| Same home, gas cut off automatically | 2 × CO + Smoke alarm (Rs 5,799 each) + gas leak detector with shut-off valve (Rs 8,500) | 20,098 |
Have a qualified gas fitter install the shut-off valve on the gas line, and plug the mains-powered gas detectors into a socket on your UPS or inverter circuit so they keep working in power cuts.
Where to install a carbon monoxide detector
- In every room where a gas heater, angeethi or geyser runs, and in the rooms where people sleep.
- On the wall or ceiling, as the instructions in the box show. The alarm is designed for ceiling or wall mounting.
- Not right next to the heater flame, and not in a steamy bathroom, where it can give false alarms.
- Where you will hear it from your bed.
Testing, batteries and beeping
Press the test button once a month. Because the alarm runs on AA batteries it works through load-shedding, and it warns you when the batteries are low. A short chirp now and then usually means the batteries need changing; a loud, continuous alarm means it has detected CO or smoke. Beep patterns vary between models, so keep the leaflet that comes in the box.
If the CO alarm goes off
- Open doors and windows.
- Turn off the heater, angeethi or geyser if you can do it safely.
- Get everyone out into fresh air, including anyone who is drowsy.
- Call Rescue 1122 if anyone has a headache, dizziness or nausea, or is hard to wake.
- Do not go back in or relight the heater until the cause has been found and fixed.
For gas leaks, where you must also avoid any spark, follow the steps in our winter gas leak detector guide.

Frequently asked questions
How much does a carbon monoxide detector cost in Pakistan?
At ZZ Marts, the CO + Smoke Dual Sensor Alarm costs Rs 5,799. It detects carbon monoxide and smoke, shows the CO level on an LCD and runs on AA batteries.
Does a gas leak detector detect carbon monoxide?
No. A gas leak detector senses unburnt fuel gas such as Sui gas or LPG. Carbon monoxide is made when fuel burns without enough fresh air, and it needs a CO detector.
Where should I put a carbon monoxide detector?
In each room where a gas heater, angeethi or geyser runs and in rooms where people sleep. Fix it on the wall or ceiling as its instructions show, not right next to the heater flame and not in a steamy bathroom.
Does a CO detector work during load-shedding?
The CO + Smoke Dual Sensor Alarm runs on AA batteries, so it keeps working when the electricity goes. Replace the batteries when it gives its low-battery warning.
What should I do if the carbon monoxide alarm goes off?
Open doors and windows, turn off the heater if you can do it safely, get everyone into fresh air, and call Rescue 1122 if anyone feels unwell. Do not go back in until the cause has been found.
How do I protect a whole home from gas leaks and carbon monoxide?
Put a CO alarm in each heater room and a gas leak detector in the kitchen. For a home with two heater rooms and a Sui gas kitchen, that is Rs 16,897 with the LCD gas detector, or Rs 20,098 with the gas detector that shuts off the gas automatically.
