Batteries
Both the door sensors and PIR Motion Sensors have included batteries, as does the
remote control. These are necessary for the alarms to be able to transmit an active
wireless signal. The functionality of the sensors is reliant on the batteries providing
power in much the same way as a smoke detector.
We recommend changing the batteries in all sensors every six months.
The expected life of the batteries is actually considerably longer than this (they’ll
probably last for a year or more). However the consequences of the batteries
running low can be so dramatic that we strongly recommend changing to fresh
batteries long before there is a chance that they’ll run down - much like the
recommendations for smoke detectors.
The Wireless Alarm System’s door sensor uses a single 23A battery. The remote
control uses a 27A battery. These are usually available from specialist battery
retailers and from many locksmiths (these are a typical battery found in security
systems). If in doubt, simply take one of the batteries you’re replacing to a retailer,
and they’ll be able to tell you quickly if they stock them. The PIR Motion Sensors
use a standard 9V battery.
To change the battery in the Door Sensor:
Remove the transmitter portion of the sensor
•
from its mounted position.
Locate the small tab on the base of the rear
•
cover, on the bottom of the sensor in its mounted
orientation. Using a flat head screwdriver, pry off
the rear cover.
Locate the 12V 23A battery, located in a small
•
battery clip near the bottom of the printed circuit
board and replace with a fresh battery - be careful
to put the new battery in the right way around.
Arm the alarm system and then test that the
•
sensor is functioning correctly.
To change the battery in the PIR Motion Sensor:
Remove the PIR sensor from it’s mounted position,
•
Locate the screw in the base of the sensor and
remove.
The 9V battery is attached via a battery clip near the
•
base of the printed circuit board.
Replace the battery with a fresh one, close the
•
sensor and replace the screw.
Test to ensure the sensor is functioning correctly.
•
To change the battery in the Remote Control:
Unscrew the three screws on the back of the
•
remote control.
Remove the front plate and the buttons. Be careful
•
not to lose the buttons or screws.
Replace the 12V 27A battery located in the middle
•
of the circuit board.
