How to Replace an ADT Motion Sensor Battery

An ADT Motion Sensor is a home alarm system which is monitored at the ADT service center. Although ADT Motion Sensors run off the main electricity, they come equipped with battery packs in case of electricity failure. If the battery begins to run low, the alarm may malfunction. The ADT service center will usually notify you if the batteries have run low, although regular checks should be performed every six weeks. Changing the batteries is a simple process which does not require any technical knowledge.
