Chuango Door/ Window Contact DWC-102 is suitable for doors, windows or any object that opens and closes. It detects if a window or door is open in real time.
It works by using a transmitter and a magnet. The magnet is placed on the door/ window, while the transmitter on the door/ window frame. Once the door or window is opened, the “contact” between the transmitter and the magnet is broken. A low-battery signal will be then transmitted to a Chuango alarm hub, triggering an alarm.
It works only with Chuango Alarm hub together and cannot be used independently.
