How do I test if my CO alarm is working properly?
Press the TEST button and the Power, Fault, and Alarm indicators will flash once simultaneously. If the alarm is functioning correctly, one cycle of alarm will sound. After cleaning or if the alarm has been dropped, always perform a test using the TEST button before reinstalling and using it.
