ALARM REMOVAL
IF SMOKE ALARM TAMPER RESIST FEATURE HAS BEEN ACTIVATED, REFER
TO SMOKE ALARM TAMPER RESIST FEATURE IN SECTION 3 FOR REMOVAL
INSTRUCTIONS.
To remove the alarm from the trim ring, rotate the alarm counter clockwise in the
direction of the "OFF" arrow on the cover. To disconnect the A.C. power harness,
squeeze the locking arms on the sides of the Quick Connector while pulling the
connector away from the bottom of the alarm (see Section 3, Figure 7).
BATTERY INSTALLATION AND REMOVAL
To replace or install the batteries slide the battery door in the direction indicated
on the cover of the alarm. The battery can then be pulled out of the carrier.
When installing a new battery into the carrier, make sure that the polarity
matches the markings printed on the inside of the battery compartment.
Completely slide the battery door to the closed position.
A missing or improperly installed battery will prevent the battery door from clos-
ing and result in improper alarm operation.
This smoke alarm uses a 9V carbon zinc battery (alkaline and lithium batteries
may also be used). A fresh battery should last for one year under normal operat-
ing conditions.
This alarm has a low/missing battery monitor circuit which will cause the alarm
to “chirp” approximately every 30-40 seconds for a minimum of seven (7) days
when the battery gets low.Replace the battery when this condition occurs.
NOTE: Low/missing battery monitor circuit WILL cause the unit to chirp while
replacing the battery. This function will cease once the new battery has been
installed. To avoid this “chirp” the unit can be removed from the base and dis-
connected from the AC power when replacing the battery, but it is not necessary.
