Linear's ACT-34B is a four-channel device that comes equipped with a quick-disconnect key ring and a unique 10-second time-out feature. Each transmitter is factory-preprogrammed with one of over 1,000,000 codes, effectively eliminating the possibility of code duplication. Furthermore, the receiver learns each specific code, ensuring that no unauthorized person can gain access by reprogramming a transmitter. The block-coded transmitters are factory-programmed to a sequential series of transmitter ID codes, and facility codes can be selected to further customize the system, making it compatible with all Linear access receivers and controllers.

The ACT-34B's key ring feature provides a convenient way to carry the device, while the factory-programmed MegaCode format supports more than 1 million codes, offering unparalleled security and flexibility. Powered by two 2016-type lithium batteries, the transmitter operates at a frequency of 318MHz, ensuring reliable and efficient performance.
