Altronix FireSwitch108 Installation Manual page 5

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 1/8 in. Do not bend closer than 1/4 in. to the body of the resistor.
8. Connect desired 24VDC devices to regulated Aux. power output terminals marked [+ AUX --- ] (Fig. 2, pg. 4).
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]
(Fig. 2, pg. 4).
10. Connect appropriate signaling notification devices to terminals marked [AC FAIL & BAT FAIL] (Fig. 2, pg. 4)
supervisory relay outputs.
11. Program FireSwitch utilizing on-board programming switch or via ethernet port (for Programming refer to pgs. 8-12).
When using ethernet port, cable has to terminate within the same building.

This separate 1 amp max. auxiliary regulated output circuit is typically used to power 4-wire smoke

detectors - 0.45 amp for Canadian applications. See attached list of devices (Appendix B, pgs. 18-19).
Notification appliances are connected to these regulated outputs. Each power limited output will
OUT1 - OUT8 supply up to 2.5 amp. Outputs are controlled by designated input 1 [IN1] or input 2 [IN2]
(Supervised) (Output Configuration Chart, pg. 8). Maximum line impedance 1 ohm. NAC outputs that are
programmed as AUX are Special Application.
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. Terminal polarity is shown in alarm
IN1+, IN1 -- condition. During an alarm condition these inputs will cause the selected outputs chosen to drive
IN2+, IN2 -- notification appliances. The designated outputs are programmable [OUT1 through OUT8] (Output
(Supervised) Configuration Chart, pg. 8). A trouble condition 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.
For Class A hookups these terminal pairs return to FACP.
RET1+, RET1 -- For Class B hookups use FACP EOL resistor to terminate at these terminals.
RET2+, RET2 -- Optionally, additional signaling circuit power supplies may be connected to these terminals.
(Supervised) If this option is chosen the EOL resistor must be terminated at the last device. Up to twelve (12)
units can be interconnected.
EARTH Connects to the grounding lug of enclosure (factory installed).
These are dry contact trouble outputs that report any general loop/system trouble conditions.
