Did you know that you can add wireless control and sensors to your HAI OmniLT, Omni II or OmniPro II automation controller (all sold separately)? The 64-Zone Wireless Receiver wires into your controller and translates signals sent from up to 64 wireless devices, including handheld controllers and wireless sensors. Install the 64-Zone Wireless Receiver in a central area in your home or business, as high above ground as practical. You can teach the receiver the addresses of up to 64 transmitters; the number supported depends upon which controller it's connected to. A status LED flashes when it receives a message from a transmitter. A variety of wireless transmitters is available to communicate with your HAI controller. Hang a 4-Button Keyfob Remote on your keychain for easy on/off control of your security or lighting systems. Install Door/Window Transmitters at each entry point for instant alerts upon a breach. You can even install a Pet-Immune Motion Detector for motion-sensing security that won't be confused by your pets. All wireless sensors and transmitters are sold separately.
