There are several different styles of wireless sensors, including door, window, motion, smoke detection, etc. each having their own battery requirements. Please refer to the manufacturers instruction first. Open the sensor, get proper replacement battery, replace, and put sensor back together. When completed, go to keypad follow the steps under Option #1 or Option #2:
Option #1
- Press and hold the number 2 button for three seconds, until the display shows “sensor reset”
- Release the button, which will tell the system to rescan the sensors and it will see the new battery
Option #2
- Press the command until the display reads ” menu no yes”
- Press button on keypad under “yes”
- Enter your security code
- When the display reads “sensor reset”, press the top left button under the word “sensor”
NOTE – sensors have a tamper switch that detects if the cover is in place. If the zone shows faulted after working on it, it may be that the cover is not seated properly to make contact with the tamper switch. Also, some sensors have a spring that protrudes from the tamper switch, which can “fly off” when removing the sensor cover.
