You home security system will constantly check for low battery signal on all wireless devices. If a low battery is detected, the transmitter sends a low battery message to the control panel, which beeps and displays the detector’s zone number. Be sure to replace batteries with a fresh one.
BATTERY REPLACEMENT INSTRUCTIONS
- Put your alarm system into TEST mode (typically by entering your user code plus the number 5 [TEST] plus the number 0 on the touchpad). The alarm sounder will sound momentarily. While the alarm system is in the TEST mode, the touchpad will beep about every 30 seconds.
- Remove the transmitter’s cover using the finger latch (some older models may require inserting the flat blade of a small screwdriver into the pry-off slot at the bottom end of the unit on the right side closest to the cover’s decorative ribs and twisting).
- Remove existing battery from the transmitter, carefully lifting it out with a small screwdriver. Wait at least 30 seconds before installing the new battery.
- Observe correct polarity and install a new CR123A Lithium battery into the battery holder (see diagram below). Take care not to bend the antenna.
- To replace the cover, engage the hooks along one edge and snap shut.
- Activate the transmitter by opening and shutting the door or window. The touchpad will beep 3 times confirming reception.
- Exit the alarm system TEST mode by entering your user code plus the number 1 (OFF). Enter your user code plus the number 1 (OFF) again. The low battery message should disappear.
