Ac Power Wiring; Nac Class B Wiring; Nac Class A Wiring - General Signal Building BPS6 User Manual

Note 1: A trouble on the
Booster will be sensed on the
existing fire panels NAC circuit
causing an NAC trouble on that
panel.
In an alarm condition, the
Booster will allow NAC current
to move downstream to
devices connected to the
existing fire panel's NAC
circuit.
Note 2: Refer to the connected
fire alarm control panel's
documentation for more details
on making NAC wiring
connections.
