General considerations

Notice!

Before connecting panels into a network, each panel needs to be individually programmed
and then added to the network.

For programming details, see the 

FPA-1000 Installation and Operation Guide

.

Notice!

All wiring except the battery terminal and primary AC power is power-limited. Phone lines are
also generally considered to be non-power-limited.
Power-limited and non-power-limited circuit wiring must remain separated in the cabinet by
at least 0.25 in. (64 mm) and must enter and exit from the cabinet through different
knockouts or conduits. Phone lines are generally considered to be non-power-limited, so the
cables for networking cards should not be run through the same knockout as the phone lines.

Interconnecting network cards

4.2.1

Class X/Class B connections

A network can be connected as Class X or Class B. The network circuit is supervised.
Class X configuration is recommended because this allows the panels in a network to
communicate with each other ensuring circuit operation in the event of a single fault in the
wiring. For information on control panel signaling requirements for SLCs when a fault exists
on the network, see 

NFPA

72 National Fire Alarm and Signaling Code

.

Notice!

The network cards have built-in isolators automatically making the Class

A loop connecting

the networked panels into a Class X circuit.

On Class

X circuits, no T-taps are allowed. For Class

X connections, the return side of the

circuit must be routed separately from the outgoing circuit and the return side must not share
the same conduit or cable as the outgoing side of the circuit. For an example of a network, see
the following figure.
