Altronix AL175ULX Access Control Power Supply and Charger Installation Guide

Overview:

Altronix AL175ULX is a power-limited power supply/charger that will convert 115VAC / 60Hz input into two individually PTC protected auto-resettable 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 the Fire Alarm Control Panels.

Installation Instructions:

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 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 the 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, pg. 8).

2. Connect AC power to the black and white flying leads of the transformer. Secure green wire lead to earth ground. Green “AC” LED on power supply board will turn on. This light can be seen through the LED lens on the door of the enclosure. 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 (115VAC / 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.

3. Set the AL175ULX to the desired DC output voltage by setting switch SW1 to the appropriate position (Power Supply Output Specification Table).

4. Measure output voltage before connecting devices. This helps avoiding potential damage.

5. Connect battery to the terminals marked [+ BAT –] (battery leads included).
   Use two (2) 12VDC batteries connected in series for 24VDC operation.
   Note : For Access Control applications batteries are optional.
   When batteries are not used, a loss of AC will result in the loss of output voltage.
   When the use of stand-by batteries are desired, they must be lead acid or gel type.

6. Connect appropriate signaling notification devices to AC Fail supervisory relay outputs marked [NC, NO, C].
   Note : To meet UL requirements, AC Supervisory outputs must be connected to the zone of Alarm Control Panel or to visual AC trouble indicator.

7. For Access Control Device & Fire Alarm Interface connections refer to desired Application Diagrams (pg. 6-7) and Terminal Identification Chart (pg. 5).

Maintenance:

Unit should be tested at least once a year for the proper operation as follows:

Output Voltage Test: Under normal load conditions the DC output voltage should be checked for proper voltage level (see Power Supply Output Specifications Chart).
Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage both at the battery terminal and at the board terminals marked [+ BAT –] to ensure that there is no break in the battery connection wires.
Note: Maximum charging current under discharges is 400mA.
Note: Expected battery life is 5 years; however, it is recommended changing batteries in 4 years or less if needed.

CAUTION: De-energize unit prior to servicing.
For continued protection against fire hazard replace fuses with the same type and rating.
Do not expose to rain or moisture

CAUTION: Optional rechargeable stand-by batteries must match the power supply output voltage setting.
Keep power-limited wiring separate from non power-limited. Use minimum 0.25″ spacing.
