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 regu-
lated and filtered 24VDC power to Class B or Class A NAC loop circuits. Additionally, a separate 1 amp auxiliary output
for 4-wire smoke detectors is available. Alarm current can be divided between the eight (8) outputs for powering NAC
devices. Outputs are rated at 2.5 amp max., and can be independently programmed for Steady, Temporal Code 3 or Strobe
Synchronization. All outputs may be programmed for Input to Output Follower Mode (output will follow input. i.e. March
Time Input, March Time Output). In non-alarm condition independent loop supervision for Class A and/or Class B FACP
NAC circuits is provided. In the event of a loop trouble, the FACP will be notified via the steered input (input 1 or input
2). In addition, there are common trouble output terminals [NC, C, NO] which are used to indicate general loop/system
trouble. Two (2) FACP signaling outputs can be employed and directed to control supervision and power delivery to any
combination of the eight (8) outputs. It provides a programmable LCD display interface, plus an ethernet port interface for
remote programmability and monitoring.
