Remote Keypad
When the battery is low the 'low-batt' LED on the
keypad will be illuminated.
Note: The Keypad will retain your User Access
Code setting for approximately 15 seconds whilst
the battery is removed and replaced. If the battery
is left disconnected for a longer period, or has been
allowed to run completely flat your User Access
Code will revert to the factory set code of "1 2 3 4 "
when the new battery is connected. The User
Access Code will then need reprogramming as
detailed on page 9.
PIR Movement Detectors
Under low battery conditions the LED behind the
detector lens will flash when movement is detected
to indicate that the battery needs to be replaced.
Under normal battery conditions the LED does
not illuminate unless the PIR Detector is in Walk
Test Mode.
Magnetic Door / Window Detectors
When the Detector is activated, under low-battery
conditions the Transmit LED will be illuminated
for approximately 1 second as the door/window
is opened.
Under normal battery conditions the LED does
not illuminate as the Detector is operated, (unless
the Detector is in Test Mode with the battery
cover removed).
