The FireAngel FA3820-EUX10 is a carbon monoxide alarm with a 10-year sealed lithium battery. An advanced electrochemical sensor, calibrated and tested in CO gas, detects carbon monoxide quickly and accurately, and an intelligent algorithm heightens sensitivity when low-level CO is detected.
A ventilate pre-alarm warns of low CO levels before the main alarm, giving time to open windows and find the source, and a 30-day memory logs previous alarm activations. It should be installed in any room with a fuel-burning appliance, and it replaces end-of-life CO-9X alarms.
