FireAngel FA3322 Carbon Monoxide Alarm User Manual
CO Alarm
The alarm’s high sensitivity mode will be enabled if the alarm predicts CO levels will increase to or above 180ppm for fast reaction to rising CO levels.
4 audible chirps and a red warning flash pattern every second
Ventilate instruction
With low level CO monitoring, a pre‑alarm warning to open windows helps reduce the risk of CO poisoning and prevents build‑up of dangerous CO levels. If a room is not ventilated and ppm levels continue to increase, the alarm will activate.
2 audible chirps and a yellow warning flash pattern every 4 seconds
Power on/activated
A continuous green flash indicates your CO alarm is activated and protecting your home.
Consistent green flash
Alarm memory
If a CO alarm incident has occurred during your absence, the red LED will flash to indicate that dangerous CO levels have been detected in your absence.
No audible chirps but two red warning flash patterns every 20 seconds
Sleep easy
Silence low battery chirps for 8 hours, up to 10 times, to provide vital time to take action and replace your batteries.

Night time sensing
When low ambient light levels are detected at night time, the alarm will lower the light output.
