Wall-mounted metal enclosure for 24 V DC 10 A security power supply

ALTRONIX

ALTRONIX AL1024ULACMCB 24 V DC 10 A security power supply

SKU CH-RERR-4553N MPN AL1024ULACMCB

Delivers 24 V DC at 10 A across eight protected outputs with selectable fire-alarm disconnect for mag-locks and strikes

  • TypeProprietary Power Supply
  • Eight independently selectable fire alarm disconnect outputs
  • 10 A continuous 24 V DC power for multiple devices
  • circuit and thermal overload protection on every output
  • Wall-mount enclosure measuring 15.5 by 12.2 by 4.5 inches
  • RoHS certified and built in the United States

Eight outputs with fire-alarm disconnect

The ALTRONIX AL1024ULACMCB converts 115 V AC at 60 Hz into eight independently controlled 24 V DC Class 2 power-limited outputs rated for a total of 10 A continuous current. Each output is PTC protected and can be configured as fail-safe or fail-secure. The fire-alarm disconnect is individually selectable for any or all outputs and accepts normally open, normally closed or polarity-reversal inputs from a fire-alarm control panel.

Replaces fused multi-output supplies

The PTC-protected design removes the need to replace blown fuses after a short circuit or overload, reducing maintenance on access-control installations. The unit mounts on a wall and occupies a 15.5 by 12.2 by 4.5 inch enclosure weighing approximately 11.75 lb. Upgrading from a fused equivalent is worthwhile when service calls for fuse replacement are frequent or when latching and non-latching fire-alarm disconnect must be mixed on the same panel.

Ten-amp headroom for mag locks and strikes

The 10 A capacity comfortably runs multiple mag locks, electric strikes and magnetic door holders simultaneously across the eight outputs. An alarm relay with a form C contact rated at 1 A and 28 V DC signals when the fire-alarm input is triggered. The supply reaches its limit when the combined load exceeds 10 A or when a single output draws more than its Class 2 rating, so systems requiring higher current per output or more than eight zones need additional power supplies.

Questions about this item

What wall space and clearance does the 15.5 by 12.2 by 4.5 inch enclosure need for mounting?

The unit measures 15.5 inches high, 12.2 inches wide and 4.5 inches deep, so allow at least that footprint plus room for conduit entry and ventilation around the metal cabinet.

How do I set the fire-alarm disconnect for a specific output, and which step is often missed?

Move the jumper for each of the eight outputs to the latching or non-latching position, then connect the FACP dry-contact or polarity-reversal input; the step often missed is verifying the alarm-output relay (form C, 1 amp 28 VDC) actually toggles when the FACP triggers.

When will the PTC-protected outputs need attention after a fault?

Each of the eight 24 VDC Class 2 outputs uses a self-resetting PTC; after a short or overload the device cools and restores power automatically, so no fuse replacement is required unless the PTC itself fails after repeated events.
