Installation Instructions

The AL400ULB should be installed in accordance with article 760 of The National Electrical Code or NFPA 72 as well as all applicable Local Codes.

1. Mount AL400ULB in the desired location/enclosure (mounting hadware included).

2. Connect 28VAC / 175VA transformer to the terminals marked [AC AC], (Fig. 1).
   Use 18 AWG or larger for all power connections (Battery, DC output).
   Use 22 AWG to 18 AWG for the power-limited circuits (AC Fail/Low Battery reporting).
   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 AL400ULB to the desired DC output voltage by setting the switches to the appropriate positions
   (Power Supply Output Specifications Table).

4. Connect devices to be powered to the terminals marked [+ DC –] (Fig. 1).

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

6. 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 battery to the terminals [– BAT +] (Fig. 1) as marked on the unit (battery leads included).
   Use two (2) 12VDC batteries connected in series for 24VDC operation.

7. Connect supervisory trouble reporting devices to the outputs marked [LOW BAT, AC FAIL] supervisory relays marked
   [NC, NO, C ] (Fig. 1). Use 22 AWG to 18 AWG for AC Fail and Low Battery reporting.

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
(Power Supply Output Specifications Table).
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 1.25A.
Note: Expected battery life is 5 years; however, it is recommended changing batteries in 4 years or less if needed.
