Replacing Smoke Detector Batteries

Batteries should be replaced annually or when low. See page 32 for the

procedure used to test the transmitter battery power and operation.

To Replace Batteries:

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 leads pointed to the center of the transmitter, as shown in the figure

at the

right.

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).

Test the detector to be sure it operates properly.

NOTE: Different manufacturers make

9-volt

alkaline batteries in

slightly different case sizes. To ensure proper fit and performance in

your smoke detector, You should use only Duracell MN1 604.
