In low light ambient conditions, the green LED ring fades to off, and then blinks approx every 60 seconds. This
unit samples the ambient light conditions of the alarm’s location and, if possible, determines a Night / Day
cycle. A valid Night / Day cycle will delay unit chirps during the night until the next Day cycle begins.
cHirpinG
When chirping begins during the next Day cycle, you can
temporarily silence End of Unit Life or Network Error chirps
by pressing the Test/Hush button. Low Battery chirps
cannot be silenced.
If a valid Night / Day cycle has not been established because the unit is located in either a constantly dark or
lighted location, the chirps mentioned above will not be delayed at night. Moving the unit to a different location
might allow the unit to determine a valid Night / Day cycle.

:
If you know why the alarm is sounding, and you can verify that it is not a life threatening situation,
you can push the button on the initiating unit (green LED flashing every second) to silence the alarm for
8-10 minutes. If the smoke is not too dense, that unit, and all interconnected units will silence. After the Hush
®
period, the smoke alarm will automatically reset and sound the alarm if particles of combustion are still
present. You can use Hush
®
repeatedly until the air has been cleared of the condition causing the alarm.
