Alarm.com ADC-PSU-A2-12V1A Replacement Power Supply

Product Description

The ALARM.COM INCORPORATED ADC-PSU-A2-12V1A is a replacement power supply finished in white, designed to restore reliable low-voltage DC power to compatible security and automation control equipment. Power supplies in this class convert standard AC line voltage to a regulated DC output, providing the stable power that control panels, hubs, and peripheral devices require for consistent operation. Installation is typically performed by licensed low-voltage or alarm technicians as part of a system repair or upgrade. The white finish suits flush-mounted or surface-mounted installations in residential and light commercial environments.

This power supply is suited for use in security, access control, and home automation applications where a regulated DC power source is required. It is intended as a direct replacement unit, allowing technicians to swap out a failed or aging power supply without replacing the entire control assembly. Typical installations are found in residential panels, small commercial alarm systems, and smart-home hub enclosures where low-voltage DC power distribution is required.

Key Features

• Direct replacement design simplifies swap-out during service calls
• White finish coordinates with standard panel and enclosure interiors
• Sold as a single unit for targeted replacement without full-assembly changeout
• Intended for low-voltage security and automation control applications

Compatibility

Designed as an OEM-style replacement power supply for compatible ALARM.COM INCORPORATED control and automation equipment requiring a 12-volt DC power source.

Installation Notes

Installation should be performed by a licensed low-voltage or alarm systems technician in accordance with applicable local codes and NFPA 72 guidelines. Disconnect and de-energize the system completely before removing the existing power supply. Verify output voltage and polarity match the requirements of the connected control equipment before applying power. Do not attempt installation with the system live or while the panel is armed.
