Key Features

CARBON MONOXIDE ALARMS FOR HOME USE: The advanced electrochemical sensor detects dangerous levels of carbon monoxide (CO) in your home, alerting you with 4 loud chirps (85 dB(A) at 3 metres) and a flashing red ‘CO’ LED light.

ENHANCED SENSING: The alarm’s high sensitivity mode will activate if it predicts that CO levels will rise to or above 180 ppm, providing a quicker alert and a ‘pre alarm’ with a visual instruction to ‘ventilate'.

10-YEAR SEALED FOR LIFE BATTERY: Each CO monitor is fitted with a sealed, tamper proof, 10 year battery that will last the lifetime of the alarm. A flashing amber '!' and an audible beep will alert you when the device needs replacing.

ALARM MEMORY: Your device will notify you of a CO alarm in your absence. If not silenced, the alarm will continue to sound until CO levels are safe. The red ‘CO’ light will continue flashing as a visual indication of a previous activation.

PORTABLE CARBON MONOXIDE DETECTOR: Measuring 125 x 67 x 33 mm, this compact, free standing device is travel friendly and provides protection wherever you go. It also includes an integrated mounting bracket and screws for easy wall mounting.

SAFETY ASSURED: Suitable for all domestic and rental premises, the FA3820 carbon monoxide monitor is UKCA marked, Kitemark certified, and third-party approved by the British Standards Institute (BSI) to BS EN 50291-1:2018 and EN 50291-2:2019.

FIREANGEL HOME PROTECTION: In addition to our carbon monoxide detectors, we offer a wide range of other safety products designed to protect you and your family. Choose from smart and wireless devices, as well as standard fire, smoke, and heat alarms.
