Replacing Smoke Detector Batteries
Batteries should be replaced annually or when low.
See page 22 for the procedure used to test the
transmitter battery power and operation.
To Replace Batteries:
To avoid generating a false alarm, you must set
your system to the Test mode (see page 22).
Remove the smoke detector from the mounting
bracket by pressing the black tab on the side
marked PRESS. Lift the detector away from
PRESS and lift up until the top is free from its
hook.
Remove both old batteries and discard them.
Wait at least one minute before inserting new
batteries. This allows the Low Battery detector in
the transmitter to reset. Replace the batteries
with two
9-volt batteries (Duracell MN1604 only).
Insert the batteries with connectors pointed to
the center of the transmitter, matching
plus and
-
minus, as shown below.
5 Re-attach the detector to the mounting bracket
by hooking it at the top, then swing the bottom
down until it snaps into place (you may need to
press the detector into the bracket at both top
and bottom).
6 Test the detector to be sure koperates properly.
7 Take system out of Test mode (see page 22).
NOTE: Different manufacturers make 9-volt
alkaline batteries in slightly different case sizes.
To ensure proper fit and performance in your
smoke detector, only Duracell MN1 604 will fit.
