If it has not been changed recently, it's time to change the battery in the sensor. You will need one 3V CR123A battery.
A door and window contact requires (1) CR123 3-volt battery (in some systems, the door and window contact will be a very slim device and will contain a single, CR2032 battery). This battery can often be purchased at your local hardware, mass retailer or battery store.
The motion detector requires (1) CR123A 3-volt battery.

Possible Causes of False Alarms:
Obstructions: Bugs, cobwebs, or dust covering the sensor might affect its sensitivity. Incorrect Positioning: If the sensor is not positioned correctly, it might pick up unrelated noises. Low Battery: A low battery can sometimes lead to erratic behavior of the sensor.
When you order on MyADT, your QSP provides one free system battery per year. Additional system batteries cost $29.99.
A low battery warning is most often displayed as BAT, LOW BATT or SYSTEM LO BAT on the touchpad. This warning signals that your battery is low and must be either recharged or replaced. ADT offers several battery-replacement options for our customers, including a self-service option on most systems and devices.
A glass break sensor is a sensor that detects the vibrations in the glass surface it is connected to. The device will trigger an alarm in case an intruder breaks the glass and consequently tries to enter your facility.
This switch may need to be reset. Additionally, taking the batteries out and putting them back in again can work. For some sensors, it's necessary to press the button on the glass break sensor a set number of times, pause, then press it again. That resets the sensor and allows it to continue working normally.
Expected battery life is up to 3 years with the included batteries. Battery life is dependent on device settings, usage, environment, and other factors.
Most systems can take either a 12V 7Ah or a 12V 4Ah battery. The 4Ah size is used in smaller panel boxes. A few systems may use different voltage and Ah ratings.
Slide the Glassbreak Sensor off of its mounting bracket. This will expose its CR-123A Lithium 3V battery, which can then be replaced.
If so, the device will run on its backup battery for up to 24 hours, and you will get a low battery alert as it is depleted. If AC power is not restored before the battery dies, the device will power down.
Most security experts agree that in order to provide the most protection, both glass break sensors and window sensors are recommended. Here are a few reasons why having both types of sensors in your home can provide safety and peace of mind: Protection against both forms of entry.
Because glass break sensors work by analyzing sound frequency, it is possible that certain sensors will be set off by a loud dog bark or even a powerful gust of wind.
