Notes
[1]
Maximum 25 Ω resistance per wire. Maximum circuit capacitance of 0.1 µF.
[2] Maximum 12 AWG (2.5 sq. mm) wire; minimum 18 AWG (0.75 sq. mm) wire
[3] Refer to the control panel technical reference manual for wiring specifications
[4] If the NAC power riser is used for more than one notification zone, install in accordance with the survivability from attack by fire requirements in
NFPA 72
[5] Supervised
– Class A or Class B
[6] Polarity shown in active condition. Polarity reverses on supervisory condition
[7] Typical synchronized temporal horn/strobe circuit when configured as Class A/B auto sync signal output module through programming
[8] Transient protection (see
“Transient protection caution” below)
[9] Supervised, 16.5v trouble threshold. Approximately 20 second delay fault reporting
[10] In order to have a Class A output of the FX-NAC the SLC inputs must be Class A and the power input circuit needs to be in same cabinet or
containted within the same room by no more than 20' in conduit.
[11] For further wiring information, refer to panel documentation
Transient protection caution
The module requires transient protection for installations that connect
electromechanical bells or horns to output circuits. The module's
circuitry requires a bipolar transient protector (P/N 235196P) for
protection against transient spikes caused by the inductive load of
bells or horns.
Connect the bipolar transient protector assembly across the terminals
of the bell or horn electrically closest to the module. The bipolar
transient protector is not polarity-sensitive.
Locate bells and horns at least 6 ft. (1.83 m) from the module.
