Axxess Zigbee Contact Sensor (CS-C4ZB-11-W)
The Axxess Wireless Contact Sensor transmits information on whether a door or window is open or closed. Using a magnetic switch the device transmits two different signals: CLOSED, when the magnet makes contact and OPEN, when the magnet breaks contact.
Long Battery Life
Our contact sensor uses a single 1/2 AA Lithium battery. They stand apart from other batteries in their high charge density (long life), constant voltage and temperature range.
