HAI
Mini Transmitter
The Vanishing Door/Window Mini Transmitter from HAI is a thin, supervised wireless contact that works with the HAI 45A00-1 wireless receiver. It has beveled edges that vanish into a building's décor and transmits to the HAI controller if a door or window is open or closed. A bypass button lets users manually bypass the transmitter, which is restored when the door or window is closed.
