Wireless Rolling Garage Door/Window Sensor

Detector Overview
These detectors are are used on rolling doors such as garage doors. If a burglar opens a protected door, a magnetic switch inside the sensor will activate which will notify the security system of the break-in. The transmitter part is installed on the wall or floor near the door and the magnetic part installed on the garage door. When the door opens, it should separate the two parts. The transmitter is powered by a 23A 12v battery.

Door Chime Feature
When the system is disarmed, opening a door or window will cause the alarm panel to sound a door chime to let you know it's been opened. Great for front and back doors when you want to know where the children are.

Includes: garage door sensor, magnet, and wireless transmitter (Normally Closed NC).
