Battery replacement

Under normal conditions, the LED normally flashes every 8 sec to indicate normal operating
conditions. Replace the battery when the LED stops flashing, and the sensor chirps every 45
sec.

the Smoke detector illustration for locating the Test/Silence button.

Smoke test

Test smoke detectors annually by using a listed aerosol smoke tester to simulate an alarm.
Follow the instructions on the can.
The LED should remain ON while the detector provides a continuous tone. The detector
automatically resets when smoke is no longer present. A detector that fails to activate with
the smoke test might require cleaning or replacement.
Notice!
To avoid a fire department dispatch, contact central monitoring station, or put the system
into Test mode before activating the detector using this method.
