Installation Instructions

The AL300ULXB2 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 the AL300ULXB2 in the desired location/enclosure (mounting hardware included).

2. Set the AL300ULXB2 to the desired DC output voltage by setting SW1 (Fig. 2, pg.2) to the appropriate position (refer to Power Supply Voltage Output Selections chart).

3. Connect AC power (115VAC / 60Hz) to the terminals marked [L, G, N] (Fig. 2, pg.2). Use 18 AWG or larger for all power connections (Battery, DC output, AC input). Use 22 AWG to 18 AWG for 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.

4. Connect devices to be powered to the terminals marked [+ DC –] (Fig. 2, pg.2).

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 marked [+ BAT –] (Fig. 2, pg.2). Use two (2) 12VDC batteries connected in series for 24VDC operation (battery leads included).

7. Connect appropriate signaling notification devices to AC FAIL & BAT FAIL (Fig. 2, pg. 2) supervisory relay outputs.
   Note : When used in fire alarm, burglar alarm or access control applications, “AC Fail” relay should be utilized to visually indicate that AC power is on. To delay report for 6 hours cut “AC Delay” jumper (Fig. 2a, pg. 2).

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 (refer to Power Supply Voltage 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 discharge is 0.7A.
• Note : Expected battery life is 5 years; however, it is recommended changing batteries in 4 years or less if needed.

Terminal Identification

ground.
+ DC –| 12VDC or 24VDC @ 2.5A continuous power-limited output.
AC Fail NC, C, NO| Indicates loss of AC power, e.g. connect to audible device or alarm panel. Relay normally energized when AC power is present. Contact rating 1A @ 28VDC. AC or brownout fail is reported within 1 minute of event. To delay reporting of up to 6 hrs., cut “AC delay” jumper and reset power to unit.
Bat Fail NC, C, NO| Indicates low battery condition, e.g. connect to alarm panel.

Relay normally energized when DC power is present. Contact rating 1A @ 28VDC.

+ BAT –| Stand-by battery connections. Maximum charge current 0.7A.
