Physical Overview
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.
PROM. 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.
