Notification Appliance Circuits Installation
There are two (2) NAC circuits provided on the PFC-6075 rated as continuous 3 amps at 24 vDC. The NAC circuits may be
configured for Class A or Class B.
(Please refer to the Class A and B wiring examples located in this section.)

same circuit rating, supervision and regulation as other circuits.
NAC Maximum Wiring Impedance Formula
The maximum impedance is a
function
of the
load
placed on the circuit. To calculate the maximum line current impedance, use
the following formula:
(Alarm Current of Notification Appliances) x (Wire Resistance) < 3 Volts
