Welcome Chirp: Horn chirps and light blinks once when batteries are first connected
Alarm Receiving Battery Power: Light flashes every minute. Horn is silent
Low Battery Warning: The light continues to flash (RED) and the horn also “chirps” once every minute. This warning should last for up to 30 days, but you should replace the batteries as soon as possible
During Testing: Light flashes Red in sync with the horn pattern (4 beeps, pause, 4 beeps), simulating a CO Alarm condition
Alarm Sounds: Sensor has detected enough CO to trigger an alarm. Light flashes rapidly and horn sounds loudly (repeating 4 beeps, pause). See “If Your CO Alarm Sounds” for details. During an alarm, move everyone to a source of fresh air. DO NOT move the CO Alarm!
