Installation Instructions
AL175ULX2 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.
-
Mount AL175ULX2 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).
-
Connect AC power (115VAC / 60Hz) to the black and white flying leads of the transformer. Secure gree 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, 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 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. -
Set the AL175ULX2 to the desired DC output voltage by setting switch SW1 to the appropriate position (see Power Supply Output Specifications Table, Pg. 2).
-
Measure output voltage before connecting devices. This helps avoiding potential damage.
-
Connect battery to 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 is desired, they must be lead acid or gel type. -
Connect appropriate signaling notification devices to AC Fail supervisory relay outputs marked [N.C., N.O., 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 and Fire Alarm Interface connections see Application Diagrams, pg. 5 – 6 and Terminal Identification Chart, pg. 3.
8. Secure enclosure door with the screws supplied to assure proper ground.
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.
Terminal Identification
| Terminal Legend | Function/Description |
|---|
TRG1 & TRG2
| These input terminals are designed to connect to the normally closed outputs
of an access control or fire alarm relay. These terminals control [LOCK+], and
[STRIKE+], as well as AL175ULX2 output relay contacts [N.C., N.O., C].
LOCK +| This terminal provides DC output voltage when [TRG1] and [TRG2] are
shorted together and are typically used to power Mag Locks.
STRIKE +| This terminal provides DC output voltage when [TRG1] and [TRG2] are
unshorted and are typically used to power Electric Strikes.
N.C., N.O., C
| Isolated dry Form “C” contacts. Shorting [TRG1] and [TRG2] together causes these contacts to switch. They are typically used for controlling multiple AL175ULX2s with fire alarm tie-in
( Fig. 4, pg. 4 ).
AUX+| Continuous positive (+) DC power output voltage. It is not affected by
TRG1, TRG2 operation.
COM –| Common negative (–) output (ground).
FACP| Spare wiring terminal used for fire alarm tie-in application ( Fig.
3, pg. 4 ).
+ BAT –| Stand-by battery connections.
SW2| Momentary reset button (on front door) is used as a manual power supply
reset after fire alarm system is restored.
AUX –| AUX neg (–) output (ground).
LED Diagnostics
Red (DC)| Green (AC)
(on front door)
| Power Supply Status
---|---|---
ON| ON| Normal function.
ON| OFF| Battery backup is powering output.
OFF| ON| No DC output.
OFF| OFF| Loss of AC. Discharged or missing stand-by battery. No DC output.
