Available in wired or wireless interfaces, they activate when separated from their sensors—triggering everything from alerts and alarms to predetermined changes in thermostat temperatures, lighting, and more.
How do door alarm contacts work?
A door and window alarm sensor works by using a sensor and a magnet. The sensor is placed on or inside the door or window frame. As soon as the magnet separates from the sensor, an internal reed switch inside the sensor will become tripped. When this happens, the sensor will send a signal to the alarm system.
