When you first power up the alarm:
The red Alarm LED will light and
the alarm will sound briefly, then the green Operate LED will light. This
indicates that the CO alarm is receiving power and that the alarm circuit
is functioning.
Within a few minutes, your carbon monoxide alarm will start monitoring for
CO and will continue to do so as long as it receives power.

5. Alarm Characteristics
Carbon Monoxide Alarm Indicator
When the alarm senses a dangerous level of CO, the unit will emit a
loud alarm pattern. The alarm pattern is 4 quick beeps followed by 5
seconds of silence. This cycle repeats as long as a dangerous CO
conditions exist. The red Alarm LED will flash the same pattern (and the
PPM will be displayed on alarms with digital displays).
WARNING:
When powered by battery backup only; after four minutes,
the alarm will sound and flash only once every minute, until the alarm is
reset or the CO is eliminated.
If the unit is unplugged it will produce a constant tone until the battery
is removed or the unit is plugged back into the wall unless the Tamper-
Resist feature has been deactivated or disabled.
WARNING:
If at any time you test the alarm and it does not perform as
described, have it replaced immediately.
