Description
The Linear ACT-31B is a compact 1-channel MegaCode® key ring transmitter designed for secure operation with Linear access control receivers and controllers. This block-coded transmitter provides dependable wireless access control while helping prevent unauthorized duplication through factory-programmed MegaCode technology.
Each ACT-31B transmitter is pre-programmed with one of over 1,000,000 unique MegaCode combinations, providing enhanced security and virtually eliminating code duplication concerns. The receiver learns each individual transmitter code, preventing unauthorized access attempts through reprogrammed remotes.
This block-coded version is factory programmed in sequential transmitter ID blocks, allowing easy enrollment into compatible Linear access control systems by entering the first and last transmitter codes from the block. Facility codes may also be selected to further customize system operation.
