trim plate, disconnect the AC quick connector and locate the small cut-out in

the middle of the product label on the back of the unit. With a small screwdriv-

er, or similar tool, move the slider towards the lock

position as indicated by the arrow. (see Figure 9) The

tamper resist feature is now active and the battery

carrier can not be opened until the tamper resist fea-

ture is deactivated.

NOTE: Before activating the battery carrier tamper resist

feature, make sure a fresh battery is installed in the

unit and that the battery carrier is properly closed. If the

battery carrier tamper resist feature is activated while the

battery carrier is open, the battery carrier will not close and the unit will be inop-

erable during the loss of AC power.

To deactivate the battery carrier tamper resist, in order to change the smoke alarm

battery, remove the unit from the trim plate (see Smoke Alarm Tamper Resist Feature

if activated), disconnect the AC quick connector and locate the small cut-out in the

middle of the product label. Using a screwdriver, or similar tool, move the slider away

from the lock position (opposite the direction indicated by the arrow). The battery

carrier can now be opened and the battery changed.

4. OPERATION AND TESTING

OPERATION: The smoke alarm is operating once A.C. power is applied, fresh

batteries are installed and testing is complete. When the smoke alarm ionization

chamber senses products of combustion, the horn will sound a loud (85db)

temporal alarm until the sensing chamber is cleared of smoke particles.

HUSH

CONTROL: The “HUSH” feature has the capability of temporarily

desensitizing the alarm circuit for up to 8 minutes. This feature is to be used

only when a known alarm condition, such as smoke from cooking, activates the

alarm.The smoke alarm is desensitized by pushing the “TEST/HUSH” button on

the smoke alarm cover. If the smoke is not too dense, the alarm will silence

immediately. The red LED will illuminate for 1.5 seconds every 8-10 seconds

while in hush. This indicates that the alarm is in a temporarily desensitized condi-

tion. The smoke alarm will automatically reset after approximately 8 minutes and

sound the alarm if particles of combustion are still present. The “HUSH” feature

can be used repeatedly until the air has been cleared of the condition causing the

alarm. Pushing the Test/Hush button on the alarm will end the hush period.

This alarm has a low battery HUSH feature. If the alarm is sounding a low

battery warning chirp, you can silence this chirp for approximately 13 hours by

pressing the Test/Hush button.

NOTE: DENSE SMOKE WILL OVERRIDE THE HUSH CONTROL FEATURE AND

SOUND A CONTINUOUS ALARM.
