TM NAC Power Extender Installation Guide FireSwitch108 - 10 amp NAC Power Extender Rev. 090414 More than just power.
Overview: The Altronix FireSwitch108 is a cost effective managed NAC Power Extender. It interfaces with 12 or 24VDC Fire Alarm Control Panels (FACP) to provide Notification Appliance Circuit expansion support, for additional horns/strobes to allow ADA compliancy. It also provides auxiliary power to support system accessories. It delivers electronically regulated and filtered 24VDC power to Class B or Class A NAC loop circuits.

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. 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.

FireSwitch Applications: 1. General Information: Altronix FireSwitch units are very versatile devices. They can be used with or without specific synchronization modules provided by some manufacturers. Multiple units can be synchronized by using either the built-in sync mode or a external synchronization module. Please note that only notification appliances with synchronization capabilities can be synchronized. Contact signal manufacturer for more detailed information.
POSITIVE Horn settings for CO alarm: Gentex, Potter - Horns must be set to Steady mode. System Sensor - Horns must be set for a coded output. NEGATIVE Fig. 9 4. Non-synchronizable NAC Appliances: INP1 RET1 INP2 RET2 OUT1 OUT2 OUT3 OUT4 When using NAC appliances not designed to support synchronization From FACP NAC 1 feature, it is recommended to use separate output circuits for audible notification appliances (horns) and visual notification appliances (strobes).
6. Synchronizing NAC Power Extender Using Built-in Sync Protocol: FireSwitch units include built-in protocols to support Amseco/Potter, Gentex®, System Sensor® or CooperWheelock® two-wire synchronizable devices, therefore an external sync module is not required (Output Programming Selection Table, pg. 6). In these modes, Input 1 is always used to activate visual notification appliances (strobes), and Input 2 is used to activate and silence audible notification appliances (strobes) (Table, pg. 6).

8. Using a Single FACP Output: When only one FACP output is available, you may connect both Input1 and Input2 to it. Wire [RET1+ and RET1-] to [INP2+ and INP2-]. Both visual and audible notification appliances will be activated simultaneously (Fig. 13, pg. 16). FireSwitch Logic Board Fig.
