13. NAC Circuits
Following table is the specification for the Notification Appliance Circuits (NAC1 and
NAC2):
Parameter
Description
Fuse
Self-resetting 1.6 A electronic
Regulated Continuous Current
Continuous DC currents cannot exceed 1.6 A from NAC 1 and NAC with the
total DC current not to exceed 3.2 A.
Regulated Pulsed Current:
Pulse DC currents cannot exceed 900 mA from NAC 1 and NAC with the total
DC current not to exceed 1.8 A.
Special Application
24 VDC @ 2.3 A continuous with the combined current of NAC 1 and NAC 2
not to exceed 3.1 A.
Supervision
EOL Device, 0400-01023
Synchronization
Synchronize the regulated output of NAC 1 and NAC 2 with authorized and
compatible synchronization modules from Gentex, Amseco, System Sensor or
Wheelock. Connect End-Of-Line-Device S2030 to the output of each
Synchronization Module installed.
The FireNET Plus Panel provides internal device synchronization
between the outputs of NAC 1 and NAC 2 when operating NAC devices
from Gentex, Amseco, System Sensor or Wheelock.
External synchronization modules must not be used on the NAC outputs when
operating in the special application mode.
NFPA Operation Type
Class B, Style Y
1. MaximumCurrentRatings
The total sum of device loads in the NAC circuit must not exceed the maximum current
specified for the FireNET Plus Panel when operating in Continuous Regulated, Pulsed
Regulated, or Special Application mode.
Note: Reference NAC manufacturer datasheets for individual device loads and then
compare the total sum to the maximum current capability of the FireNET Plus Panel in
regulated or special application mode.
2. SingleandDualCircuitSynchronization
NAC channels 1 and 2 of the FireNET Plus Panel provides single and dual circuit
synchronization. Single circuit synchronization provides a synchronized output on one of
two NAC channels. Dual circuit synchronization provides a synchronized output on both
NAC channels.
