Altronix AL1024ULACM Power Supply w/Multi-Output Power Controller

The Altronix AL1024ULACM is a commercial-grade, 24VDC access control power supply, battery charger, and eight-output power controller designed to distribute regulated power to electronic locking devices and security equipment. Combining a 24VDC, 10-amp continuous power supply with eight independently controlled, fuse-protected outputs, the unit supports electric strikes, electromagnetic locks, magnetic door holders, and compatible access control accessories. Each output can be configured for fail-safe or fail-secure operation and activated through a normally open dry-contact or open-collector trigger from an access control panel, card reader, keypad, pushbutton, or motion sensor. The integrated fire alarm control panel (FACP) interface provides individually selectable, latching or non-latching emergency power disconnect for all eight outputs. Operating from 115 VAC, 60 Hz input power, the AL1024ULACM includes automatic battery backup transfer, AC failure supervision, low-battery monitoring, and short-circuit protection. Housed in a wall-mounted BC400 metal enclosure measuring 15.5 inches high by 12.23 inches wide by 4.5 inches deep, the unit is UL 294 listed and cUL listed to CSA C22.2 No. 205 for commercial access control installations.

Altronix AL1024ULACM 24VDC 10A Eight-Output Access Control Power Supply and Charger

The Altronix AL1024ULACM Access Control Power Supply and Charger provides centralized power distribution, electronic locking control, and standby battery charging for commercial access control and security installations. Manufactured by Altronix as part of the ACM Series, this integrated power system combines a 24VDC, 10-amp regulated power supply with an eight-channel ACM8 access power controller, allowing installers to independently manage multiple electrically controlled door openings from a single enclosure. Its eight outputs can supply power to compatible electromagnetic locks, electric strikes, magnetic door holders, and other 24VDC access control devices, supporting configurations that require fail-safe or fail-secure operation. Each channel accepts an independent activation signal from a compatible card reader, keypad, request-to-exit button, passive infrared detector, or access control panel. The AL1024ULACM supports commercial offices, healthcare facilities, educational buildings, warehouses, retail properties, and institutional installations requiring centrally managed locking power. By combining power conversion, output switching, fire alarm interfacing, and battery supervision, the unit reduces the need for separate power distribution and relay assemblies.

The AL1024ULACM converts a 115 VAC, 60 Hz electrical input rated at 4.2 amps into filtered, electronically regulated 24VDC power with a maximum continuous supply current of 10 amps. The integrated ACM8 controller provides eight independently controlled outputs protected by individual 3.5-amp fuses, with the combined electrical load limited to the available 10-amp power supply capacity. Each channel can be configured as a switched fail-safe or fail-secure power output, while the controller also supports Form C relay contacts rated at 5 amps and unswitched auxiliary power connections for compatible external devices. The unit incorporates an ACM8 main fuse rated at 10 amps, short-circuit protection, thermal overload protection, and status indicators for power and relay operation. Red LEDs indicate energized output relays, while dedicated indicators provide information about AC input, DC output, and fire alarm disconnect activity. The standard BC400 steel enclosure measures 15.5 inches high by 12.23 inches wide by 4.5 inches deep (393.7 x 310.6 x 114.3 mm) and accommodates two 12V, 12Ah standby batteries. The unit weighs approximately 11.75 pounds (5.33 kg) and operates within an ambient temperature range of 32 F to 120 F (0 C to 49 C). The AL1024ULACM is UL 294 listed for Access Control System Units and cUL listed to CSA C22.2 No. 205 for Signal Equipment.

For multi-door electronic access control applications, the Altronix AL1024ULACM provides independent relay activation and configurable fail-safe or fail-secure power distribution across its eight output channels. The controller accepts eight normally open dry-contact triggers, eight open-collector sink inputs, or a combination of both, allowing integration with compatible electronic access control panels and field activation devices. A fail-safe output can be configured to remove locking power when an authorized release signal is received, while a fail-secure configuration can apply power to unlock a compatible locking device. The integrated fire alarm control panel interface accepts normally open or normally closed dry-contact inputs or polarity-reversal signals from a compatible FACP circuit. Each output can be individually selected for fire alarm disconnect operation, with latching or non-latching response options to accommodate the approved emergency release sequence. A dedicated Form C alarm relay provides indication when the fire alarm interface is activated, supporting monitoring and auxiliary control functions. The AL1024ULACM can operate from its factory-installed common power source or be configured with two electrically isolated power sources, separating controller operation from lock and accessory power when an additional compatible power supply is installed. These capabilities support coordinated door release, access control integration, and emergency egress arrangements, subject to the requirements of the connected locking hardware and applicable life-safety codes.

Installation of the Altronix AL1024ULACM access power controller uses the included indoor wall-mounted metal enclosure, which provides mounting provisions for the power supply, ACM8 controller, field wiring, and standby battery connections. The integrated sealed lead-acid or gel-cell battery charger automatically maintains compatible backup batteries and transfers to battery power when primary AC power fails, with no intentional voltage drop during the transition. The standard cabinet accommodates two 12V, 12Ah batteries connected in series for a 24V standby supply, while larger battery arrangements may be installed using an appropriately sized separate enclosure and the manufacturer's battery calculation requirements. Supervision features include AC failure monitoring, low-battery detection, battery presence monitoring, and Form C supervisory contacts for integration with compatible alarm and monitoring equipment. The AC failure notification delay is selectable between 30 seconds and 6 hours, allowing installers to configure reporting behavior according to the system's operational requirements. Electrical installation includes grounding the enclosure, connecting the designated 115 VAC supply, configuring the eight controlled outputs, establishing trigger wiring, and selecting fire alarm disconnect operation for the applicable door circuits. Unlike the Altronix AL1012ULACM, which delivers 12VDC at 10 amps, the AL1024ULACM provides a fixed 24VDC, 10-amp output. The related AL1024ULACMCB incorporates PTC-protected Class 2 outputs rather than the standard model's fused outputs. Backed by the Altronix lifetime manufacturer warranty, the AL1024ULACM combines regulated power delivery, independent eight-door output control, battery backup, and supervised fire alarm integration for commercial electronic security installations.
