How to Install the Battery
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 Sensor from the
wall to install a battery. Cut the tape to size and reattach your Sensor if the existing adhesive fails to hold it in place.
Is This Your Sensor? Make sure that your
Sensor 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 Sensor.
Did You See? There is a mark located to the
side of the Sensor (see arrow above) that
shows the recommended side to use when
matching up the Sensor with the magnet. The
same mark is found on the magnet for easy
alignment.
1. Locate the slot on the top of the Sensor
and place your fingertip into the slot
opening.
Where's the Slot? If you don't see the slot,
make sure to check the top and bottom of the
Sensor. The slot location is dependent on the
positioning of the Sensor during installation.
2. Move your fingertip down while holding the
front of the Sensor to pry the cover away
from the Sensor body.

Did You Know? Make sure not to press
down the tamper (shown above within the
blue square) when inserting the battery as
this will default the Sensor.
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. Insert the battery into the battery
compartment with the positive (+) side
facing up.
4. When the battery is inserted correctly, a
small green light will light up.
5. Align the small slots on the Sensor's body
with the small tabs on the cover and gently
press the cover against the Sensor until it
snaps into place. If the cover does not
snap easily into place, you may have it
upside down.
Confirm that the low battery alert has resolved and the equipment appears on your list of connected devices. You
should also ensure that sensor events such as door opening or motion registers as an activity on your system.
