Door/Window contact (5816WMWH)
The Honeywell 5816WMWH is a wireless, white-color, door and window alarm contact that is your first line of defense against criminals. The 5816WMWH is a great addition to any other compatible Honeywell security system. Use the included double sided tape to mount the transmitter on the door or window frame, and the magnet on the door or window. If the contacted door or window is opened while the system is armed, it will set off the alarm and send a signal to the MonitorU Central Station.
