Deactivation of the alarm is permanent.
Do not attempt to open the alarm for any reason.

Place this alarm into shut-down mode at the end of its useful service life. Once the smoke alarm 
has entered end-of-service-life mode, it is necessary to deactivate the alarm operation. This will 
stop the product end-of-service-life warning signal and also discharge the remaining capacity of 
the battery to render it safe for disposal.

on the rim of the base.

bracket.

4.  Push tip of key into the deactivation slot (keyhole) outline on label and insert fully.
5.  Turn key clockwise to the “off” position slowly approximately 3/4 turn.
6.  This will discharge the alarm battery and stop the alarm chirping after approximately one minute. 

The alarm is now ready for disposal.

7.  The deactivation key should not be removed and the alarm cannot be attached to the bracket. 

8.  Be sure to install a new alarm.

Once this alarm has been deactivated:

• 

The alarm cannot be reactivated

• 

The alarm cannot be reattached to the bracket 

• 

The alarm will no longer detect smoke

BATTERY AND ALARM DEACTIVATION

This alarm uses a sealed battery. The battery should last for approximately 10 years under normal 
operating conditions. The smoke alarm has a low battery indicator which is 2 chirps approx. every 
60 seconds. The red LED blinks on once approx. every 2 minutes.
Due to the loud 85 decibel alarm, stand at arm's length away from the alarm or use ear protection 
when testing. Weekly testing is required to ensure proper operation. Irregular or low volume sound 
may indicate a defective alarm and it should be returned for service. Follow instructions  to prepare 
alarm for shipment or disposal.
