How to Change Battery in Wireless Sensor?

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.


  1. 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.
  2. 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).
  3. Remove existing battery from the transmitter, carefully lifting it out with a small screwdriver. Wait at least 30 seconds before installing the new battery.
  4. Observe correct polarity and install a new CR123A Lithium battery into the battery holder (see diagram below). Take care not to bend the antenna.
  5. To replace the cover, engage the hooks along one edge and snap shut.
  6. Activate the transmitter by opening and shutting the door or window. The touchpad will beep 3 times confirming reception.
  7. 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.page9image16808

I'm probably going to end up bniyug this alarm package but you really need to do some research on sound decibel ratings. To anyone that knows anything about sound, they will laugh at a 160 db siren rating. I engineer 80,000 watt concert systems that peak at 143-145db. 150db is a jet engine at take off. AT the engine, not a 1000 feet away. When you say almost 300db need to do more research. Every time you double the speakers you gain 3db of output. You don't add the ratings together.
