Batteries
Both the Window/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.
Window/Door Sensor: 3 x LR44 Button Cells
The battery compartment on the Window/Door Sensor is located on the front of the alarm unit. To open it:
•Press in at the top of the battery compartment cover and slide down.
•Remove any old batteries.
•Insert three fresh alkaline LR44 button cell batteries. The correct orientation is to have the “+” side of the battery facing up.
PIR Motion Sensor: 3 x AAA
The battery compartment on the PIR is located on the rear of the sensor, just underneath mounting bracket slot. To change the batteries:
•Push the top of the battery compartment cover in, and push down to remove.
•Replace the three AAA batteries with fresh alkaline AAA batteries. Be sure to insert the batteries in the orientation indicated on the rear side of the battery compartment.
Remote Control: 1 x 27A
To change the battery in the remote:
•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.
The keypad control unit does not require batteries.
It is powered by the included 9V adaptor.
•If you’re concerned about potential power failures, you may consider using a small UPS
