The TB-M/D Intercom and Selective Door Control System is designed for communication between a central master
station and remote door stations. The TB-M/D adds door release to the standard TB-M system. All information
regarding installation other than the external control functions is included in the TB-M instructions. In addition to
communication to remote locations, the Master Station can selectively release the corresponding door strike or
maglock.
