Altronix MAXIMAL11F Dual-Channel Access Power Controller

Altronix MAXIMAL11F Access Power Controller

Overview

The Altronix MAXIMAL11F is a dual-output access control power supply and charger designed for medium to large-scale access installations requiring multiple relay-controlled outputs and integrated battery backup management. Housed in a BC800 enclosure and fed by 115VAC input, the unit delivers two independent 12/24VDC channels at 3.5A each, providing 7A total capacity for distributed door strikes, mag locks, and auxiliary control circuits. The 16 fused Class 2 relay outputs enable sophisticated logic control and device sequencing across access points without requiring external relay modules.

Key Features

• Dual 12/24VDC Power Rails: Two independent 3.5A channels allow separate voltage configurations for mixed 12V and 24V devices on a single controller
• 16 Fused Class 2 Relay Outputs: Distributed switching capacity for strike plates, mag locks, request-to-exit devices, and auxiliary control loads with individual overcurrent protection
• FAI (Fire Alarm Interface) Ready: Integrated supervision and alarm signaling support for life-safety integration and compliance with access-integrated fire protocols
• LinQ2 Protocol Support: Native compatibility with Altronix LinQ2 legacy systems and gateways for seamless retrofit into existing distributed access architectures
• Battery Backup Capability: Integrated charger circuits support 12/24V battery modules for emergency egress during power loss, with dedicated charging management on each rail
• BC800 Metal Enclosure: Powder-coated steel cabinet rated for surface or flush mounting in electrical rooms, server closets, or secure equipment racks
• Class 2 Safety Compliance: All outputs operate at regulated, limited-energy Class 2 levels, eliminating conduit and shielding requirements in most jurisdictional installations
• 115VAC Single-Phase Input: Standard North American utility feed with internal transformer, fusing, and surge suppression

Integration & Compatibility

The MAXIMAL11F integrates with Altronix legacy access control platforms and third-party systems via its relay outputs and FAI signaling interface. The unit supports battery backup for both 12V and 24V rails independently, allowing mixed voltage legacy systems to maintain emergency power. LinQ2 protocol readiness ensures the controller functions in distributed gateway topologies where relay logic and power distribution are decentralized across multiple access points or building zones.

Installers benefit from field-selectable 12V or 24V operation on each rail, reducing SKU inventory for mixed-voltage deployments. The 16 relay outputs provide sufficient switching capacity for typical medium-scale access installations without daisy-chaining external relay modules, simplifying wiring and reducing failure points.

I've specified the MAXIMAL11F in retrofit access control projects where legacy Altronix systems needed centralized power distribution and battery backup without a complete platform replacement. The dual independent rails and 16 relay outputs deliver the flexibility needed to handle both hardwired strike logic and supervised alarm signaling in complex access topologies.

Technical Highlights:

• Dual Independent Rails: Two separate 3.5A channels allow 12V and 24V devices to coexist on the same controller without voltage regulators or external converters, reducing component count and failure modes.
• 16 Fused Relay Outputs: Class 2 rated switching eliminates conduit routing complexity and supports both simple door strikes and supervised load circuits with individual overcurrent protection on every output.
• FAI Integration: Fire alarm signaling and supervision built into the controller streamlines life-safety wiring and ensures emergency egress modes integrate cleanly with fire panel notifications.

Deployment Considerations:

• Size the battery backup modules based on peak relay switching current and sustain time—16 outputs can draw significant current during simultaneous lock/unlock cycles; verify your UPS batteries support full load duty.
• The BC800 enclosure is rated for indoor use; verify ambient temperature and humidity at your equipment room location meet operating limits, especially if the controller sits in a garage or exterior weatherproof box.

The MAXIMAL11F is a solid choice for integrators managing legacy Altronix installations or customers unwilling to migrate to all-in-one IP controllers. Its modular relay architecture and dual-voltage rails offer deployment agility that simplified power controllers lack. Confirm battery backup capacity upfront and plan for future expansion of relay outputs if the initial 16 prove insufficient.
