3.4.3 B-Door: Lock Relay, Alarm Relay,

General Purpose Outputs 1 and 2 (TB7)
TB7 can serve one of two purposes depending upon the configuration of the controller’s satellite
board: as the B-Door Lock Relay and Alarm Relay OR as general purpose outputs 1 and 2. Make
the wiring connections for either Lock/Alarm Relay usage or for general purpose outputs (TB7).
Use Figure 10 on page 10 to locate the correct connectors for each controller.
For the Lock Relay, power is applied to the common line. This provides flexibility, allowing you to
provide power to the lock depending upon the type of lock you have.
NOTE: If the controller is configured for TB1 general purpose output 1 operation, the
corresponding door lock relay jumper may need to be removed (see Table 1 on page 7 for jumper
identification). Remove the jumper for non-powered/dry-contact operation; leave the jumper in
place for powered operation.
