Terminal Blocks. The D9210B comes with three banks of terminal blocks for
connecting the D9210B to its power source, the panel and associated readers
and relays.
Relay. A removable (model D136) relay provides a dry contact single pull, double
throw output.
Dipswitch. The D9210B dipswitch has six on-off switch settings. Setting these
switches allows each unique D9210B to be programmed for a specific address.
EPROM. The D9210B is controlled by a programmable read-only memory
microprocessor.
Diagnostic and Status LEDs. The D9210B has a series of light emitting diodes
(LEDs) for identifying operational and diagnostic states. These are listed below.
