Protect your family from invisible carbon monoxide with an accurate, loud, easy-to-install CO alarm
- silent, odourless CO leaks from gas furnaces
- no warning of dangerous gas levels
- alarm failure during power cuts
- hard-to-read CO levels
Catch invisible carbon monoxide before it reaches your family
Carbon monoxide gives no smell or warning, so your home can run a quiet leak through the night. This alarm shows the live ppm level and sounds an 85 dB siren, so you wake to safety instead of symptoms.
Read the air, not just the alarm

Live ppm reading you can actually see
The LCD shows the current CO level in ppm, so you can watch normal air day to day instead of waiting for an alarm to tell you something is wrong. A green LED flashes in normal operation.

Loud enough to wake the house
The siren sounds at 85 dB and the red alarm LED lights up with it. A central button lets you test the alarm or silence it.

Keeps working when the power goes out
Three AA batteries run the alarm independent of mains power, so it keeps monitoring through storms and outages when a plug-in unit goes dark.

From guessing to knowing
The leak you cannot smell
Your furnace runs all winter and carbon monoxide gives nothing away. Headache and drowsiness look like flu, and by then the gas has built up overnight.
A warning that finally speaks
A live ppm reading and an 85 dB siren turn an invisible risk into a clear signal. You can see the air and hear the danger.

Set it up before winter
Three AA batteries, two screws and a manual are all it takes. Press the test button and you know it works in seconds.

Questions and answers
Yes. It is made to watch the air around gas appliances. Mount it in the hallway outside bedrooms or at a distance from the appliance, as the manual directs, rather than right next to a vent.
It carries an international standard mark and a sensor built for CO. The live ppm display lets you see what it reads, and the test button confirms the siren works. Check it monthly.
The unit shows a low-battery indication. Replace all three AA batteries as soon as it appears, since low batteries can stop the siren.
Yes. It runs on 3 x 1.5V AA batteries, not mains power, so it keeps monitoring when the grid is down.
It mounts with two screws and two plastic anchors, which leave small holes. If you cannot drill, check your lease first.
No. It detects carbon monoxide only. Keep separate smoke alarms installed alongside it.
