NORMAL OPERATION
In normal operation, the alarm will flash the red LED indicator once every 30 seconds.
ALARM CONDITION

The alarm condition will be signified by a repetitive alarm sounding pattern of 4 short beeps followed by 5 seconds of silence. Immediate evacuation is required. Pushing the test button will silence the alarm for approximately 4 minutes. After approximately 4 minutes, the alarm will again sound until the unsafe CO concentration is removed.
TROUBLE CONDITION
