Test sensors
Test sensors periodically to verify operation. With the system disarmed, open the door or window. This
separates the sensor and magnet and notifies the system. You will hear a chime each time you open and
close the door or window.
Battery installation and replacement
Replace low batteries with a model CR2 battery, available from www.BluebyADT.com or other retailers.
To install or replace the batteries:
1.
To remove the sensor’s rear cover using your finger to pull it from the housing.
2.
Remove the existing battery and dispose of it properly.
3.
