How to Install the Battery

Before proceeding, make sure that your system is disarmed. Working on devices while the system is armed can
generate false alarms.
Did You Know? If you need to remove your Sensor from the wall to install a battery, you may want to have some double-
sided tape on hand. Use the tape to reattach your Sensor if its existing adhesive fails to hold it in place.
Is This Your Sensor? Make sure your Sensor looks
like the one in the image. If it does, you have the
correct document to find out how to install a battery in
your Sensor.
1. Slide the battery cover to expose the battery as
shown. The cover will slide a short distance and then
stop.
After sliding the battery cover, you may receive a
tamper alert from your system. The tamper alert warns
you when the cover of your device is open and will
clear once the battery is replaced and the cover has
been closed.
Note: Do not press the factory reset button. If you do,
close the battery compartment fully, and then repeat
step 1.
Take a look: If a battery is already present, remove it
by placing your fingertips on either side in a pinching
motion, at the positive (+) end of the battery. Then
gently pull it free from the slot.
