The Central Processor Unit (CPU) consists of the
microprocessor and the circuits, which act as the
primary interface between the network and the remote
annunciators. Two RS-485 communication ports provide
network and annunciator loop connections. An RS-232
port provides a connection for the printer or the
download cable to the fire alarm control panel. Relay
contacts provide supervision for alarms, supervisory
conditions, and trouble conditions.
The CPU functions as a node on a Class A (Style 6) or
Class B (Style 4) network. It also functions as a
controller by sending and receiving tokens (in peer-to-
peer fashion) to other controllers.
The CPU receives its power from a listed Primary or
Auxiliary Power Supply. The CPU also provides its own
protection from transient spikes, which may arise from
any source, including the power supply.

Warning!
Wire Stripping Guide
Strip 1/4" from the ends of ALL wires that connect to the terminal blocks of
the module.
CAUTION:
Exposing than 1/4" of wire may cause a ground fault.
Exposing than 1/4" of wire may result in a faulty connection.
