Chirping
When chirping begins during the next Day cycle, you can temporarily
silence End of Unit Life 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.
WARNING: REPLACE UNIT AS SOON AS POSSIBLE WHEN IN END OF UNIT LIFE OR LOW BATTERY MODE.
11. Recognizing Nuisance Alarms
Smoke Nuisance
HUSH®: 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.
NOTE: Dense smoke will override Hush® and sound a continuous alarm. If no fire is present, check to see if
one of the reasons listed in “Locations to avoid” may have caused the alarm. If a fire is discovered, get out and
call the fire department.
POSSIBLE CHIRPING REASONS
