Be alerted when the door or window is opened
The door and window access transmitter alerts you when a door or window in your home is opened. This unit consists of two small magnetic contact bars and a transmitter. When the door or window is opened, the two bars lose magnetic contact, triggering the transmitter. The transmitter then sends a signal to the receiver. Requires use of Silent Call Receiver; see related products below the image.
Easy to install. Operates on one (1) 9V battery (included). Range of up to 100 feet.
The transmitter portion of the unit must not be installed or mounted on a metal surface.
