HAI’s 57A00-1 vanishing mini transmitter for doors and windows is an ultra-thin wireless contact that works with the HAI 45A00-1 wireless receiver. Beveled edges enable the device to blend into its surroundings. The unit transmits to the HAI controller if a door or window is open or closed and features a bypass button that allows manual bypass of the transmitter.
