8. How to Replace the Battery in your Door Sensor
Door sensors use one AAA battery. Battery life will vary based on use.
NOTE: extreme temperatures can cause your batteries to deplete faster than normal
WHEN IT IS TIME TO REPLACE THE BATTERIES, PLEASE FOLLOW THESE STEPS:
1. Make sure your alarm system is disabled to avoid a false alarm
trigger when you are changing the battery in the sensor.
2. Push the door sensor up to remove it from the frame
3. Use a very small Philips head screwdriver to loosen the screw to take
the cover off
4. Take out the old battery and replace it with a new AAA battery
PLACE BACK THE COVER AND SCREW IT BACK TIGHTLY. SLIDE THE SENSOR BACK INTO THE
DOOR FRAME. MAKE SURE THE SENSOR FITS PROPERLY INTO ITS PLACE AND DOES NOT COME
OFF.
