Circuit (NAC). The LED blinks with each poll received. On
command, it activates its internal relay. The M300CJ super-
vises Class B (Style Y) or Class A (Style Z) notification or
control circuits.
Upon code command from the panel, the M300CJ will dis-
connect the supervision and connect the external power sup-
ply in the proper polarity across the load device. The discon-
nection of the supervision provides a positive indication to
the panel that the control relay actually turned ON. The ex-
ternal power supply is always relay isolated from the com-
munication loop so that a trouble condition on the external
power supply will never interfere with the rest of the system.
Rotary switches set a unique address for each module. The
address may be set before or after mounting. The built-in
TYPE CODE (not settable) will identify the module to the
control panel, so as to differentiate between a module and a
sensor address.
