Installation Instructions:

The AL400ULXB 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 AL400ULXB in desired location/enclosure.

2. Set the AL400ULXB 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).

Connect AC power (115VAC 50/60Hz) to 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 .25” spacing must be pr

ovided.

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

Measure output voltage before connecting devices. This helps avoid 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 terminals marked [+ BAT – ] (Fig. 2, pg. 2). Use tw

o (2) 12VDC batteries connected in series for

24VDC operation (battery leads included).

The Altronix AL400ULXB is a UL Recognized Power Supply/Charger designed to convert a 115VAC 50/60Hz input into a Class 2 Rated power-limited 12VDC or 24VDC output. It is suitable for various applications including Access Control System Units (UL 294), Power Supplies for use with Burglar-Alarm Systems (UL 603), and Power Supplies for Fire Protective Signaling Systems (UL 1481).

Function Description:

The device acts as a power supply and charger, providing regulated DC power and battery backup capabilities. It features automatic switch-over to a stand-by battery upon AC failure with zero voltage drop. The output voltage is selectable between 12VDC and 24VDC via a switch (SW1). It also includes supervision features for AC failure, low battery, and battery presence, indicated by form "C" contacts. Visual indicators (LEDs) are provided for AC input and DC output status.

Important Technical Specifications:

Input Rating: 115VAC 50/60Hz, 1.45 amp.

Signaling Notification: Connect appropriate signaling notification devices to AC FAIL & BAT FAIL supervisory relay outputs. For fire alarm, burglar alarm, or access control applications, the "AC Fail" relay should be used to visually indicate AC power status. A 6-hour delay for AC fail reporting can be set by cutting the "AC Delay" jumper.

Visual Indicators (LED Diagnostics):

Red (DC) ON, Green (AC) ON: Normal operating condition.
Red (DC) ON, Green (AC) OFF: Loss of AC, Stand-by battery supplying power.
Red (DC) OFF, Green (AC) ON: No DC output.

Terminal Identification:

L, G, N: Connect 115VAC 60 Hz. (L to hot, N to Neutral, G to ground).
– DC +: 12VDC @ 4 amp or 24VDC @ 3 amp continuous power-limited output.
AC Fail (NC, NC, NO): Indicates loss of AC power. Relay normally energized when AC power is present. Contact rating 1 amp @ 28VDC.
BAT Fail (NC, C, NO): Indicates low battery condition. Relay normally energized when DC power is present. Contact rating 1 amp @ 28VDC.
+ BAT –: Stand-by battery connections. Maximum charge current 1.2 amp.

Maintenance Features:

Annual Testing: The unit should be tested at least once a year for proper operation.
Output Voltage Test: Under normal load conditions, check the DC output voltage for the proper level (refer to the Power Supply Voltage Output Specifications chart).
Battery Test: Under normal load conditions, check that the battery is fully charged. Verify the specified voltage at both the battery terminal and the board terminals marked [+ BAT –] to ensure no break in the battery connection wires.
Maximum Charging Current: The maximum charging current under discharge is 0.7 amp.
Battery Life: Expected battery life is 5 years; however, it is recommended to change batteries in 4 years or less if needed.
