Linear MegaCode Block Coded Visor Transmitter 2-Channel ACP00746

The Model MT-2B 2-Channel Block Coded Visor Transmitter is designed for use with Linear's access control products. The Model MT-2B is a two-channel device. Pressing the left button on the transmitter will send a channel one signal. Pressing the right button on the transmitter will send a channel two signal. A visor clip is included. 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. Block coded transmitters are factory programmed to a sequential series of transmitter ID codes. When used with a Linear access controller, transmitters can be locally or remotely programmed into memory by entering the first and last codes of the block into the system. Facility codes can be selected to further customize the system.
