Altronix AL175ULX Installation Instructions - Manual

Overview:
The AL175ULX is a power limited power supply/charger that will convert 115VAC / 60Hz input, into two individually
PTC protected 12VDC or 24VDC outputs, (see specifications). It is intended for use in applications requiring UL Listing
for Access Control System Units (UL 294) and applications requiring an interface with Fire Alarm Control Panels.
Specifications:
Power Supply Output Specifications:

12VDC SW1 Open 1.75 amp 1.75 amp 12VDC
24VDC SW1 Closed 1.75 amp 1.75 amp 24VDC
Stand-by Specifications:
Output 4 hr. of Stand-by &
5 Minutes of Alarm
12VDC / 7 AH Battery Stand-by = 1.25 amp
24VDC / 7 AH Battery Alarm = 1.25 amp
Installation Instructions:
The AL175ULX should be installed in accordance with article 760 of The National Electrical Code or NFPA 72 as well
as all applicable Local Codes.
See Terminal Identification Chart on page 3 for a description of each terminal function.
1. Mount the AL175ULX in desired location.
2. Connect AC power to the black and white flying leads of the transformer. Secure green wire lead to earth ground.
Use 18 AWG or larger for all power connections (Battery, DC output). Use 22 AWG to 18 AWG for power
limited circuits (trigger inputs, dry outputs).
Keep power limited wiring separate from non-power limited wiring (115VAC / 60Hz Input, Battery Wires).
Minimum .25” spacing must be provided.
3. Set the AL175ULX to the desired DC output voltage by setting switch SW1 to the appropriate position
(refer to Power Supply Output Specification Table).
