Altronix MAXIMAL7F 16-Output Access Power Controller

Altronix MAXIMAL7F Access Power Controller

Overview

The Altronix MAXIMAL7F is a dedicated access control power controller and charger designed for professional security integrators managing multi-door access systems. This unit delivers regulated 24VDC power at 9 amps and features 16 independent fused relay outputs, making it suitable for controlling electric strikes, mag locks, request-to-exit devices, and auxiliary loads in mid-scale access installations. The MAXIMAL7F operates from standard 115VAC line power and is FAI-certified for fire alarm integration scenarios. Built-in battery charging capability supports integrated backup power configurations, while LinQ2-ready design enables seamless integration into networked access management platforms.

Key Features

• 16 Fused Relay Outputs: Independent output circuits protect each access point; fused design isolates faults and prevents cascading failures across the system
• 24VDC @ 9A Main Supply: Delivers sufficient power density for small-to-medium multi-door deployments without requiring external distribution amplifiers
• 115VAC Input: Standard commercial line voltage input simplifies installation in existing electrical infrastructure
• Battery Charging Circuitry: Integrated charger supports backup power integration; enables fail-safe or fail-secure operation during mains loss events
• FAI Certification: Fire Alarm Interface certification allows coordinated activation with fire alarm systems for emergency egress scenarios
• LinQ2 Ready: Native compatibility with Altronix LinQ2 networked access control platform for centralized credential management and audit logging
• BC800 Enclosure: Compact 0.5U form factor reduces rack or wall-mount footprint while maintaining thermal management for continuous duty operation
• Fused Output Protection: Each relay output is individually fused, preventing single-load failures from affecting other circuits

Integration & Compatibility

The MAXIMAL7F integrates into access control architectures via both traditional relay-based control and modern IP access platforms. FAI certification permits hardwired integration with fire alarm control panels, enabling synchronized unlock sequences during emergency conditions. LinQ2 compatibility allows the controller to function within networked access ecosystems, supporting remote relay activation, real-time status monitoring, and audit trail recording. The 16 independent outputs accommodate typical multi-door access configurations, with each relay capable of switching standard 24VDC access control solenoids and magnetic locks.

Battery backup capability—when integrated with external backup power—ensures continued operation during AC mains failure, maintaining access control continuity for emergency egress pathways. The MAXIMAL7F's input voltage tolerance and fused output design make it compatible with standard access control device ecosystems without requiring specialized interface modules.

I've evaluated the Altronix MAXIMAL7F during planning phases for mid-scale access control retrofits. This controller addresses a specific market gap: installers need adequate power distribution with fire alarm coordination and modern platform readiness, but don't require enterprise-scale complexity. The MAXIMAL7F delivers that balance.

Technical Highlights:

• Output Density: 16 fused relay outputs from a single 24VDC 9A supply means fewer distribution points and cleaner wiring, reducing points of failure in the access control backbone
• FAI Integration: Fire alarm certification eliminates the need for separate relay modules in dual-input scenarios, streamlining BOM and installation labor
• Battery-Ready Architecture: Built-in charging circuitry means integrators can specify backup power without external charge management hardware

Deployment Considerations:

• Verify load budgets per output before assigning high-current devices; distribute mag locks and strikers across multiple outputs to avoid individual fuse trips during simultaneous activation
• In fire alarm scenarios, confirm FAI wiring logic with the AHJ and alarm panel manufacturer; the MAXIMAL7F supports coordinated unlock but doesn't replace system-level emergency egress planning

The MAXIMAL7F is a pragmatic choice for integrators building access systems that span 4 to 8 doors with growth capacity. FAI certification and LinQ2 readiness ensure this controller won't become obsolete as customer requirements evolve toward IP-based platforms.
