The AND-BTN-KIT-1 is a vandal proof button kit. AND’s call button allows for most of AND’s devices to become intercoms for hands free, bidirectional communications. Connect the IP endpoint via SIP to your IP phone network and talk from office to classroom and classroom to office at the push of a button. Program the button to recognize two commands. Push to talk to the office; push and hold to connect to campus or district security. Once connected, simply talk into the embedded microphone that is found in most of AND’s devices.
