External Network Circuit Wiring
External network circuit can address up to 110 panels and/or remote annunciators.
FW106/FW106C control panel can connect to panels/annunciators by using External Network Unit.
Remote Device Power – The control panel auxiliary power can provide power for 4 annunciators. Each address
on the circuit must be fully powered from either auxiliary power of control panel UL/ULC Listed power supply
for use in fire alarm systems.
When connecting panels/annunciators on the external network circuit, the data wires must be daisy chained
and with no T‐taps to preserve the integrity of the data. The following diagrams show the proper wiring.
