Cleaning Your Alarm
Over time dust might collect inside your alarm, altering its performance. If this
occurs, the unit can false alarm or the WARNING icon will flash and the horn will
chirp every 30 seconds. To clean the alarm perform the following:
Remove the alarm from its bracket. If the
smoke alarm is wired to the AC power lines,
the wire harness must be disconnected.
Gently vacuum all the outside surfaces care-
fully or wipe with a clean cloth.
Locate the black smoke chamber on the back
surface of the smoke alarm.
If the WARNING icon flashing persists,
return the alarm to the manufacturer.
Twist the chamber counter-clockwise to
remove.
Carefully clean both the chamber and the
empty alarm cavity with compressed air.
With the AC wire harness reconnected (if
AC alarm type), re-install on the ceiling/wall
bracket with a clockwise twist.
Re-install the smoke chamber into the cavity
with a clockwise rotation. Align the dots on
chamber and housing to ensure a proper fit.
Press and release the Test button on the front
