How to Install the Batteries

Before proceeding, please be sure that your system is disarmed. Working on devices while the system is armed can
generate false alarms.
Did You Know? You may want to have some double-sided tape on hand if you need to remove your Keypad from the
wall to install a battery. Cut the tape to size and reattach your Keypad if the existing adhesive fails to hold it in place.
Is This Your Keypad? Make sure that your
Keypad looks like the one in the image. If it
does, you have the right document to find out
how to install a battery in your Keypad.
1. Remove the Keypad from the wall by
sliding it upwards until it is free of the
mounting bracket, then find the small
horizontal raised line located on the back of
the Keypad. This line is on the battery
cover.
2. Place your thumb on the horizontal line and
push toward the end of the Keypad until
the cover is removed.
Take a Look. If a battery is already present,
remove it by using your fingertip to gently pull
one end of the battery up until the battery is
loose and you can pull it free from the slot.
3. The battery compartment contains a
diagram of the proper battery position with
a symbol indicating which way the positive
(+) end of the battery should be facing.
Insert two CR123A batteries into the
compartment, positioning the positive (+)
ends of the batteries as shown in the
battery diagram.
