Securitron -u.s. AQD4-4F1R2 Supervised Power Supply 4A

Product Description

The SECURITRON -U.S. AQD4-4F1R2 is a supervised access control power supply designed to deliver regulated 12 or 24 volts DC at up to 4 amps of continuous output. It provides four individually fused outputs, allowing separate circuits to be protected and monitored without a single fault taking down an entire access control system. Supervision circuitry continuously monitors the power outputs for fault conditions, making it suitable for installations where code compliance or system integrity monitoring is required. This unit is installed by licensed security integrators, access control technicians, and low-voltage electricians as part of door access, locking, or related electronic security systems.

The AQD4-4F1R2 is suited for commercial and light industrial access control installations where multiple locking devices or access control peripherals require independent, fused power distribution. Typical applications include powering electric strikes, magnetic locks, request-to-exit devices, and access control panels. The selectable 12 or 24 volt DC output voltage allows it to match a range of field devices without requiring a separate transformer for each circuit. Its supervised design supports installations that require fault notification at the head-end panel or monitoring station.

Key Features

• Selectable 12 or 24 volt DC output to match connected devices
• 4 amp total output capacity supports multiple simultaneous loads
• Four individually fused outputs protect each circuit independently
• Supervised power monitoring supports fault detection and system integrity reporting
• Sold as a single unit (each)

Compatibility

Designed as an OEM-style replacement or new-installation power supply for supervised access control systems requiring 12 or 24 volt DC fused multi-output power distribution.

Installation Notes

Installation should be performed by a licensed low-voltage or electrical contractor in accordance with applicable NEC low-voltage wiring requirements and local access control codes. Disconnect all power sources before making or breaking any wiring connections to the unit. Verify the output voltage selector is set to the correct voltage for the connected devices before energizing. Do not exceed the rated 4 amp total output across all fused circuits.
