The Model ACT-31B One Button Key Ring Transmitter is designed for use with Linear’s access control products. The Model ACT-31B is a single-channel device supplied with a quick-disconnect key ring. A unique 10-second time-out feature prevents the system from being shut down by a single transmitter transmitting continuously. The transmitter is MegaCode format, which means each transmitter is factory preprogrammed with one of over 1,000,000 codes, virtually eliminating the possibility of code duplication. Because the receiver ”learns” each specific code, no unauthorized person can gain access to the system by reprogramming a transmitter. Part Number: ACP00879
