Remote Keypad:
When the battery is low the 'low-batt' LED on the
Remote Keypad will be illuminated.
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 Contact 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.
