6 . Determine which NAC input will trigger the desired NAC output(s) .
7 . Select output options (for Programming refer to pgs. 9-11).
Note: The 2-wire horn/strobe sync mode will only synchronize horns, horn/strobes, strobes with
synchronization capability . For Class B outputs connect EOL (AL-EOL10) to the last device in each NAC
Loop . For applications in Canada use EOL10K-C end of line resistors (to be ordered separately) . Form the
leads to fit the terminals . Bend radius can not exceed 0 .125” . Do not bend closer than 0 .25” to the body of
the resistor .
8 . Connect desired 24VDC devices to regulated Aux . power output terminals marked [+ AUX – ] (Fig. 2, pg. 5) .
Output is Power-Limited . 0 .25” spacing from Non Power-Limited wiring must be provided .
Use separate knockout .
9 . Connect Digital Communicator or Local Annunciator to Common Trouble Output terminals marked
[NC, NO, C] . Connection to triggering devices must be made within 20 ft . of distance and using conduit
for wiring (Fig. 2, pg. 5).
10 . Connect appropriate signaling notification devices to terminals marked [AC FAIL & BAT FAIL]
supervisory relay outputs (Fig. 2, pg. 5) .
11 . Program FireSwitch utilizing on-board programming switch or via ethernet port (for Programming refer
to pgs. 9-11). When using ethernet port, cable has to terminate within the same building .
12 .
WARNING: emergency control or non fire equipment cannot be connected on same circuitry as
fire alarm equipment .

Terminal Legend Function/Description
+ 24V IN –
24VDC input from power supply .
+ AUX –
This separate 1A max . auxiliary regulated output circuit is typically used to power
approved devices. See attached list of devices (Appendix B, pg. 23) .
OUT1 - OUT8
(Supervised)
Notification appliances are connected to these regulated outputs . Each power limited output
will supply up to 2 .5A . Outputs are controlled by designated Input 1 [IN1] or Input 2 [IN2]
(Output Configuration Chart, pg. 9). Maximum line impedance 1 Ohm . NAC outputs that
are programmed as AUX are Special Application .
IN1 +, IN1 –
IN2 +, IN2 –
(Supervised)
These terminals connect to the 24VDC FACP notification appliance circuit outputs . Class A
or Class B Input trigger voltage is 8-33VDC @ 6 .5mA min (12VDC or 24VDC @ 6 .5mA) .
Terminal polarity is shown in alarm condition . During an alarm condition these inputs will
cause the selected outputs chosen to drive notification appliances . The designated outputs are
programmable [OUT1 through OUT8] (Output Configuration Chart, pg. 9). A trouble condi-
tion on an output loop will cause the corresponding input to trip the FACP by opening the
FACP loop . An alarm condition will always override trouble to drive notification appliances .
RET1 +, RET1 –
RET2 +, RET2 –
(Supervised)
For Class A connections these terminal pairs return to FACP . For Class B connections use
FACP EOL resistor to terminate at these terminals . Optionally, additional signaling circuit
power supplies may be connected to these terminals . If this option is chosen, the EOL resis-
tor must be terminated at the last device . Up to twelve (12) units can be interconnected .
EARTH
Connects to the grounding lug of the enclosure (factory installed) .
C, NO, NC
(Common
trouble output)
These are dry contact trouble outputs that report any general loop/system trouble conditions .
In addition, Factory set to report AC and Battery trouble . Feature can be optionally turned off .
See Programming section, pg. 9-11. Typically used to trigger a digital communicator or other
reporting devices (form “C” contact 1A / 28VDC, 0 .35 Power Factor) . Connection to trigger-
ing devices must be made within 20 ft . of distance and using conduit for wiring (Fig. 2, pg. 5) .
+ SYNC –
Designed to be connected to [+ INP1 –] or [+ INP2 –] of Altronix FireSwitch models only .
Maximum of four (4) units can be interconnected, the distance between the units should
not exceed 20 ft ., wiring to be in conduit, 20 AWG wire minimum . FireSwitch108 NAC
power extenders must be located in the same room .
GF1
GF2
Dry normally open contact . It will close if ground fault is detected . Use to report ground
fault condition to a host FACP . Can be wired between [+] or [–] coming from FACP and
earth ground .
