• Output power:
10 amp max. total alarm current.
7 amp max. stand-by without battery back-up.
1 amp with battery back-up including
dedicated Aux. output.
For Canadian applications Stand-by with
battery backup is limited to 0.45 amp.
• 2.5 amp max current per output.
• One (1) auxiliary output rated at 1 amp
(regulated, battery backed up).
0.45 amp for Canadian applications.
• Any NAC can be configured as an Aux. output with or
without battery back-up (special application only).
When set as Aux. output, the output is not supervised.
• Programmable supervised indicating circuit outputs:
Eight (8) Class B or Four (4) Class A,
or any combination of Class A and Class B circuits.
• Thermal and short circuit protection with auto reset.
Battery Backup:
• Built-in charger for sealed lead acid or gel type batteries.
• Automatic switchover to stand-by battery when
AC fails.
• Zero voltage drop when switching over to
battery backup.
Supervision:
• AC fail supervision (form “C” contacts).
• Battery fail & presence supervision (form “C” contacts).
• Low power shutdown. Shuts down DC output terminals
if battery voltage drops below 70-75% for 24V units.
Prevents deep battery discharge.
Special Features:
• Programmable LCD display interface.
• EOL resistor value is programmable by output.
• Ethernet port interface for remote programmability
and monitoring.
• 2-wire horn/strobe Sync mode allows audible
notification appliances (horns) to be silenced
while visual notification appliances (strobes)
continue to operate.
• Sync protocols include Potter, Gentex
®
,
System Sensor
®
, and CooperWheelock
®
.
• Temporal Code 3, Steady Mode, Input to Output
Follower Mode (maintains synchronization of
notification appliances circuit).
• Compatible with 12VDC or 24VDC fire panels.
• Output loop supervision directed to input 1 or input 2.
• Common trouble Dry N.C. output for reporting
trouble to remote FACP.
• Ground fault detection - Ground fault maximum test
impedance 1,000 ohm.
• Ground fault Dry N.O. output to report ground fault
to remote FACP.
• CO Temporal Code 4 (NFPA720) include
Gentex
®
, Potter and System Sensor
®
devices.
Electrical:
• Operating temperature: 0º C to 49º C ambient.
• BTU/Hr.: 122.84 BTU/Hr.
• System AC input VA requirement: 576VA.
Visual Indicators:
• LCD display - Indicates troubles and conditions of
operation. Trouble Condition Memory facilitates
quick identification of an intermittent/fault
(short circuit, open or ground) which has previously
occurred on one or more signaling circuit outputs.
LCD displays which output the fault has occurred on.
Mechanical:
• Enclosure Dimensions (H x W x D approx.):
15.5” x 12” x 4.5” (393.7mm x 304.8mm x 114.3mm)
- Accommodates up to two (2)12VDC/12AH batteries.
• Product weight (approx.): 12.4 lbs. (5.62 kg).
• Shipping weight (approx.): 13.7 lbs. (6.21 kg).
Specifications
The Altronix FireSwitch108 is a managed NAC Power Extender. It interfaces with 12 or
24VDC Fire Alarm Control Panels (FACP) to provide Notification Appliance Circuit expan-
sion support, for additional horns/strobes to allow ADA compliancy. It also provides auxiliary
power to support system accessories. FireSwitch108 delivers electronically regulated and fil-
tered 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.
