Overview; Specifications; Installation Instructions - Altronix AL175220 Series Installation Instructions Manual

Altronix AL175220 and AL175X220 are power-limited power supply/chargers that converts 220VAC (working
range 198VAC - 256VAC), 50/60Hz input into two individually PTC protected auto-resettable 12VDC or 24VDC
outputs (see specifications). They are intended for use in Access Control applications and applications requir-
ing an interface with the Fire Alarm Control Panels. They must be installed in accordance with National and
Local Electrical Codes and Regulations.
Input:
• Input 220VAC, 50/60 Hz, 0.3A.
Output:
• 12VDC or 24VDC selectable output.
• Power-limited outputs.
• 1.75A continuous supply current @
12VDC or 24VDC.
• Aux relay output (form "C" contacts).
• Filtered and electronically regulated output.
• Short circuit and thermal overload protection.
Battery Backup:
• Maximum charge current: 400mA.
• Automatic switch over to stand-by battery
when AC fails.

The units 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 Pg. 3 for a description of each terminal function.
1. Mount unit in the desired location. Mark and predrill holes in the wall to line up with the top two keyholes
in the enclosure. Install two upper fasteners and screws in the wall with the screw heads protruding. Place
the enclosure's upper keyholes over the two upper screws; level and secure. Mark the position of the lower
two holes. Remove the enclosure. Drill the lower holes and install two fasteners. Place the enclosure's upper
keyholes over the two upper screws. Install the two lower screws and make sure to tighten all screws
(Enclosure Dimensions, pgs. 7-8).
2. Connect unswitched AC circuit (220VAC, 50/60Hz) as follows: Green branch wire (ground) connects to the
terminal marked
[N] of the Inlet Appliance Connector. (Fig. 1, pg. 4).
Use 18 AWG or larger for all power connections.
Use 18 AWG or larger for all power connections (Battery, AC input, DC outputs).
Use 22 AWG to 18 AWG for power-limited circuits (trigger inputs, dry outputs).
Keep power-limited wiring separate from non power-limited wiring (220VAC, 50/60Hz Input, Battery
Wires). Minimum 0.25" spacing must be provided.
CAUTION: Do not touch exposed metal parts.
Shut branch circuit power before installing or servicing equipment.
There are no user serviceable parts inside. Refer installation and servicing to qualified service personnel.
