u Four fuse-protected, Class 2 Rated, power‑limited

outputs

The Altronix AL400UL‑PD4R Fire Power Supply
converts a 115 V, 60 Hz input to either 4 A of
continuous supply current at 12 VDC or 3 A of
continuous supply current at 24 VDC. The supply
current is distributed through four fuse-protected,
Class 2 Rated, power‑limited outputs.

Certifications and approvals

Region Certification

USA UL ALVY: Access Control System Units (AN-

SI/UL 294), APHV: Power Supplies, Bur­glar Alarm System (ANSI/UL 603) ,and
UTRZ: Power-supply Units (UL 1481)

Installation/configuration notes

u 12 VDC or 24 VDC selectable output

u Outputs are filtered and electronically regulated

u Main power input fuse rated at 3.5 A, 250 V

u Short circuit and thermal overload protection

Mounting Considerations

Mount indoors in areas protected from rain or
moisture.

Wiring Considerations

Use 14 AWG (ISO 2.5 mm2) or larger wiring for all
power connections (battery, DC output, AC input). Use
22 AWG to 18 AWG (ISO 0.34 mm2 to 0.75 mm2)
wiring for power limited connections (AC fail, low
battery reporting).

Notice

Maintain a minimum of 0.25 inch (0.64 cm)
spacing between power limited wiring and wiring
that is not power limited (AC input, battery
wires).

Battery Considerations

The power supply accommodates up to two 12 VDC,
7 Ah standby batteries and automatically switches to
battery power if AC input power fails. When batteries
are not used, a loss of AC power results in a loss of
output voltage. When batteries are used, they must be
lead‑acid or gel type.
