Key features of our new range

Our latest range of carbon monoxide alarms offer a variety of new safety features.

Enhanced CO sensing

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.

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.

Alarm memory

FireAngel's new CO alarm range

With the alarm memory function, the red LED will flash to provide a visual indication of a previous CO alarm activation.

Night sensing & sleep easy

Night sensing lowers the brightness of alarm’s heartbeat sensor and automatically activates ‘sleep easy’ mode, allowing residents to silence low battery chirps for 8 hours, up to 10 times.

Quiet self-test

Simple testing, quieter volume. Residents have convenience of the quiet self-test function for regular, discreet testing at a reduced noise level. Discover more.

How many CO alarms are needed for a property?

Following amendments to the Smoke and Carbon Monoxide Alarm (England) Regulations 2015, since October 1st 2022 a carbon monoxide alarm is now required in all rooms where there is a fixed combustion appliance – such as gas boilers or gas fires – once the compliance date is announced. However, gas cookers are excluded from the updated regulation.

Landlords must also repair or replace alarms when notified of a fault, but regular alarm testing will remain the responsibility of the resident. The smoke and CO alarms must comply with BS EN 14604 (Smoke) and EN 50291‑1 (CO) and carry a British or European approval mark, such as a Kitemark.

Please note, only the sealed battery CO alarms, including the FA3820, FA3322 and FA3328, are suitable for homes in Scotland under the new fire and CO regulations.
