Altronix LINQ8ACM 8-Output Network Power Controller
Overview
The Altronix LINQ8ACM is a board-level power distribution controller designed for security integrators and system architects who need centralized power management across multiple access control devices, door strikes, and magnetic locks in networked security infrastructures. This is not a standalone power supply—it's a component you install into larger enclosures or appliances where distributed power control across eight independent circuits is required. Each output carries its own fuse, so a fault on one circuit (a shorted solenoid lock, for example) won't cascade and shut down power to other devices. That isolation matters in multi-door deployments where a single failure can compromise egress or system continuity.
Key Features
- 8 Independently Fused Outputs: Per-output fusing prevents a short or overcurrent on one device from affecting the other seven circuits—critical in installations where door strikes and magnetic locks share the same power controller and any single failure could lock occupants in or out.
- Integrated Battery Backup: Maintains power to designated emergency circuits during AC power loss, ensuring that emergency egress pathways remain functional and critical access control devices stay powered through brief power events or facility brownouts.
- Fire Alarm Disconnect: Automatic isolation of protected circuits when building fire alarm systems activate, ensuring compliance with life safety codes (e.g., NFPA 72, IFC 702) that mandate power removal from certain access control hardware during fire events.
- Network-Based Power Management: Supports IP-based monitoring and control integration into converged security management platforms, allowing remote power cycling and circuit status visibility from a central VMS or access control system.
- Board-Level Form Factor: Compact PCB design fits inside standard control cabinets, integrated appliances, and larger power distribution enclosures without consuming significant rack or shelf space.
- Fused Distribution Architecture: Eliminates single points of failure across auxiliary device loads; each output is individually protected, so troubleshooting and maintenance focus on the affected load, not the entire system.
Integration and Compatibility
The LINQ8ACM integrates into networked access control platforms where distributed power control across multiple door hardware, electronic locks, and ancillary devices is required. Its board-level configuration allows installation into larger power distribution systems, control cabinets, and integrated security appliances. The battery backup functionality supports emergency egress requirements and maintains critical circuit power during facility power interruptions or brief outages. Fire alarm disconnect integration enables proper coordination with building fire safety systems and ensures code compliance in installations that combine access control and life safety requirements.
When planning system architecture, consider the LINQ8ACM in multi-door or multi-zone access control deployments where you need per-circuit power isolation and emergency backup without deploying separate power supplies for each device. The fused output design is particularly valuable in warehouse automation and distributed security environments where fault tolerance and load segregation reduce downtime from component failures.
Deployment Considerations
The LINQ8ACM is a power management board, not a power supply unit. You integrate it into an enclosure alongside a main power input and battery backup components. Verify that your main AC power source and battery backup system are correctly sized for the total load across all eight outputs. Document which devices (door strikes, locks, readers) are assigned to each output so that during troubleshooting or maintenance, a blown fuse affects only the intended load and not unrelated circuits.
Frequently Asked Questions
Q: Can I use the LINQ8ACM standalone, or does it require an external power supply?
A: The LINQ8ACM is a board-level component designed for integration into a larger enclosure. You supply AC main power and battery backup as separate components; the board distributes and manages that power across eight outputs with fuse protection and fire alarm disconnect logic.
Q: What's the maximum current per output, and how do I size the fuses?
A: Refer to the product datasheet for maximum current ratings per output. Fuse sizing should match the expected continuous draw of each connected device with appropriate safety margin; oversizing fuses defeats the isolation purpose.
Q: Does the LINQ8ACM work with industry-standard access control systems?
A: Yes, the board integrates into networked access control and security management platforms via IP-based monitoring and control. Compatibility depends on your specific VMS or access control platform; verify integration support with your system integrator.
Q: What happens to the outputs if the fire alarm is triggered?
A: The fire alarm disconnect feature automatically isolates protected circuits when the building fire alarm activates, removing power from access control hardware as required by life safety code.
Q: Is the battery backup automatic, or does it require configuration?
A: The battery backup is integrated into the board and maintains power to designated circuits during AC loss. Configuration and assignment of which circuits remain powered under battery depends on your system design and should be planned during installation.

In distributed access control architectures, the LINQ8ACM board has proven valuable where centralized power management from a single enclosure eliminates the need for multiple smaller power supplies scattered across a facility. The per-output fusing design reflects a practical approach to load isolation: a shorted solenoid lock on output 3 will blow only that fuse, leaving outputs 1, 2, 4–8 energized. That's the operational difference between a single point of failure (one power supply for all loads) and a fault-tolerant design (eight isolated circuits).
Technical Highlights:
- 8 Independent Fused Outputs: Each output rated for selective loads ensures that a fault on one door strike or magnetic lock does not cascade to other circuits; maintenance and troubleshooting focus on the affected load rather than system-wide diagnostics.
- Integrated Battery Backup Capability: Maintains power to emergency circuits during AC loss, keeping egress pathways functional and critical reader power alive through facility power events; essential for maintaining building code compliance during emergencies.
- Fire Alarm Disconnect Integration: Automatic circuit isolation upon fire alarm activation ensures compliance with life safety codes without requiring manual intervention or separate relay logic; a critical detail in facilities where access control and fire safety systems must coordinate power management.
Deployment Considerations:
- The LINQ8ACM is a board-level component, not a standalone unit—verify your enclosure design includes adequate main AC power supply and battery backup sizing before installation.
- Fuse selection is critical: undersized fuses cause nuisance trips on legitimate inrush current from solenoids; oversized fuses defeat isolation. Work with your systems integrator to specify fuse ratings matched to actual device draw.
- In multi-door warehouse automation or distributed security deployments, the per-output isolation design reduces downtime from component faults—a single failed lock solenoid won't disable access to other zones.
For multi-zone or multi-door access control installations where fault tolerance and emergency egress are non-negotiable, the LINQ8ACM board's fused distribution and integrated battery backup deliver both operational reliability and code compliance. This is the right choice when your system architect requires centralized power management across 8+ devices without sacrificing per-circuit fault isolation.
