HES AQD2-1R Dual Voltage Power Supply 2A with Charger and Fire Relay
The HES AQD2-1R is a compact 2-amp power supply designed for access control and security installations requiring reliable DC power delivery with integrated battery charging and emergency fire relay signaling. Its dual-voltage output (12/24VDC) eliminates the need for multiple power supply SKUs, streamlining inventory management and reducing installation time on mixed-voltage systems.
Key Features
- 2-amp regulated DC output with selectable 12V or 24V operation
- Integrated battery charger for backup power and system continuity
- Fire relay output for building fire alarm system integration
- Compact form factor suitable for wall mounting or panel integration
- Compatible with HES lock controllers, credential readers, and door automation equipment
Technical Highlights
The AQD2-1R combines three essential functions in a single enclosure: primary power distribution, backup battery maintenance, and fire alarm relay signaling. The 2-amp capacity supports multiple access control devices simultaneously, while the dual-voltage design accommodates both legacy 12V systems and modern 24V installations. Battery charging circuitry maintains emergency backup power without requiring a separate charger module, reducing wiring complexity and potential failure points.
Applications
Ideal for door access control systems, magnetic lock power supplies, credential reader installations, and integrated security environments where fire alarm coordination is required. Suitable for small to medium commercial deployments including office buildings, retail facilities, and institutional access control infrastructure.
