Replacing the batteries
Remote control: The battery can be changed by removing the screw on the back of the
remote control. Remove the back panel and replace the battery. The battery type is
CR2032 (3V, Lithium battery).
A1 Alarm unit: Slide off the back panel and replace the batteries with 2x AAA size 1.5V
Alkaline batteries.
Door sensor: Remove the back panel by sliding it off and replace the battery with a new
one. The battery type is an alkaline 23A, 12V.
PIR Motion detectors: Slide off the backpanels and replace the batteries with 2 x AAA or 3
x AAA batteries depending on the model you use.
Setting the A1 alarm unit back to factory settings
Sometimes, it might be necessary to reset the A1 alarm unit to factory settings when:
a remote control was accidentally paired when a zone was selected during the pairing
process and now the A1 treats the remote control as a sensor (pressing of a button
on the remote control triggers an alarm).
other abnormal behaviour of the system (in this case often a number of buttons was
pressed in a random fashion resulting in unpredictable behaviour).
This reset is fast and simple. The procedure includes deleting sensors and remote controls
from the A1 Alarm.
IMPORTANT: Please note that the below process disconnects all sensors and remote
controls. Pair them again by following the procedures described earlier in this document
or in the user manual.
