ADT-Monitored Door Sensors

Open and close alerts
When your system is armed, you’ll hear an electronic chirp or voice alert to let you know every time a door is opened or closed.
High-decibel siren
If an intruder tries to break into your home while the system is armed, they’ll hear your system’s high-decibel alarm, letting them know they picked the wrong house.
