for Linear Mini Remote Control Key Chain Garage Door (LD033 LD050 LS050) - 10 Pack
The Model Block Coded Key Ring Transmitter is designed for use with Linear’s access control products. The Model is a single-channel device supplied with a quick-disconnect key ring. Also included are lithium batteries with a five-year service life. A unique 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 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. Block coded transmitters are factory programmed to a sequential series of transmitter ID codes
