Single Input Universal Transmitter. The Universal Transmitters can make nearly any normally-open (NO) or normally-closed (NC) sensor a wireless device. The Universal Transmitters work with shock sensors, holdup buttons, pressure mats, temperature sensors, status relays, other devices. The Inovonics EchoStream platform uses diversity reception and advanced signal processing to reduce dead spots in transmission areas. The transmitters have superior range and reliability, and are ideally suited for commercial or residential installations. They are fully supervised and include a battery, a case tamper, and a mounting bracket.
