Altronix AL400ULACM 8-Output Access Power Controller
The Altronix AL400ULACM is a full-function access control power controller that combines power supply, battery charger, and eight independently controlled 12V/24V relay outputs in one integrated unit for centralized switching of mag locks, strikes, and door holders.
AL400ULACM Access Power Controller with Integrated Power Supply & Charger
The AL400ULACM is a full-function access control power controller with built-in power supply and battery charger, designed to simplify and centralize system power and switching. It converts a standard 115 VAC / 60 Hz input into eight independently controlled 12 VDC or 24 VDC relay outputs, while supplying up to 4 A at 12 VDC or 3 A at 24 VDC for all connected devices.
This unit routes power and control to access hardware like mag locks, strikes, door holders, and more. Each output can be individually configured as fail-safe or fail-secure and is protected via fuses. The built-in charger supports standby battery backup, and the unit offers interfaces for fire alarm (FACP) connectivity and emergency egress.
Key Features
- Integrated power & control solution, one enclosure for power supply, charger, and access switching
- Eight relay outputs, individually fused Class 2 or dry (user-configured)
- Support for 12 VDC or 24 VDC, with up to 4 A (12 V) / 3 A (24 V) continuous output
- Fail-safe / fail-secure support per output
- Battery charging & backup, automatic switchover when AC fails
- Fire alarm (FACP) interface for alarm-triggered outputs or shutdown
- Compact enclosure (BC400 style) with protective housing
Application & Integration
The AL400ULACM is ideal for access control systems where multiple locks or devices need individually switched power from a central location. With eight outputs, it’s suited for multi-door installations, gating systems, or security setups. The integrated power supply and charger reduce wiring and complexity by combining multiple functions into a single unit.
Outputs respond to trigger inputs (open-collector or dry contacts) from control panels, keypads, motion sensors, or other access devices. The FACP interface provides system-level alarm or emergency control. The design supports powering locks, strike plates, door holders, or other access controllers while ensuring each circuit is protected.
