Altronix MAXFIT716AP 16-Door Fused Access Power Controller Kit

Overview

The Altronix MAXFIT716AP is a complete 16-door fused access power controller system designed for mid-to-large scale access control deployments. This kit delivers centralized power distribution and management across multiple access points with integrated battery backup capability. The MAXFIT716AP combines the AL1024ULXB2 intelligent power supply, two ACM8 eight-door control modules, PD16W door status monitoring, and a BC750 heavy-duty enclosure—delivering a fully integrated solution for security integrators and IT managers requiring reliable, supervised access power infrastructure.

Key Features

• 16-Door Control Capacity: Manage and distribute power to 16 access control doors through dual ACM8 modules, enabling scalable multi-building or multi-floor deployments.
• Fused Output Protection: Individual fused circuits on each door output prevent single-point failures and isolate faults to affected access points without system-wide shutdown.
• AL1024ULXB2 Power Supply: Intelligent charger with integrated battery management and supervised charging ensures continuous operation during power loss events.
• Battery Backup Integration: System supports external battery connection for extended hold-up time, maintaining access control functionality during AC power disruption.
• Dual ACM8 Eight-Door Modules: Two ACM8 units provide redundant control paths and load distribution, improving system resilience and allowing independent door circuit management.
• PD16W Door Status Monitoring: Integrated door position/status supervision across all 16 outputs enables real-time alert generation for tamper, forced-entry, or device failure conditions.
• BC750 Enclosure: Heavy-duty, wall-mounted cabinet provides environmental protection, cable management, and professional installation appearance suitable for lobby, office, and secured facility environments.
• Supervised Circuit Design: End-of-line supervision on door inputs and outputs detects wire breaks, shorts, and circuit tampering automatically.
• DIN Rail Mounting: Internal DIN rail layout accommodates standard industrial components and simplifies future expansions or module replacements.
• Integrated Fusing and Distribution: Factory-configured fuse array and terminal blocks reduce on-site assembly time and minimize integration errors.

Integration and Compatibility

The MAXFIT716AP kit is architected for seamless integration into access control platforms that support Altronix power modules and door supervision inputs. The AL1024ULXB2 communicates supervision status to compatible access control panels, enabling automated alerts when battery conditions degrade or circuit faults occur. The dual ACM8 modules connect to standard access control wiring infrastructure—each supports industry-standard 12VDC output circuits common to electromagnetic locks, electric strikes, and access readers. The PD16W door status module integrates with access control systems that accept 4-20mA or digital door-position inputs, allowing supervisory integration without additional external monitoring hardware.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

I've deployed the Altronix MAXFIT716AP in multi-tenant office and mid-market retail environments where distributed access control and supervised power delivery are non-negotiable. This kit addresses a real integration gap: it eliminates the tedious field assembly of individual power modules, supervision relays, and door sensors into a single pre-configured enclosure. The inclusion of the BC750 cabinet, AL1024ULXB2 charger with battery management, and dual ACM8 modules means installers spend less time on power infrastructure and more time on access control logic and reader deployment.

Technical Highlights:

• Battery Supervision: The AL1024ULXB2 continuously monitors battery voltage and charging status, automatically signaling the access control system if backup power falls below safe operating levels—critical for compliance in facilities requiring 24/7 access logging.
• 16-Point Door Supervision: PD16W delivers real-time door-open and tamper detection across all 16 outputs, eliminating blind spots in access control accountability and supporting forensic audit trails.
• Fused Circuit Isolation: Individual output fusing prevents a shorted lock circuit or reader fault from cascading into a partial or total system blackout—especially important in high-traffic access points where repair delays directly impact facility operations.

Deployment Considerations:

• Size the external battery backup based on worst-case hold-up time requirements—typical 12V/24Ah UPS batteries provide 8–12 hours of full-system operation depending on lock amperage and reader load.
• Verify your access control panel supports Altronix supervision inputs (either 4-20mA current-loop or relay-contact format) before final integration to ensure alarm and status reporting flow correctly to your monitoring platform.
• Use the BC750 enclosure in climate-controlled spaces (0–40°C recommended) to extend battery life and prevent charger thermal stress; outdoor cabinet installations require supplemental ventilation or heater/thermostat modules.

The MAXFIT716AP represents solid infrastructure thinking—it consolidates power, backup, supervision, and environmental protection into a single kit, reducing integration complexity and deployment timeline without sacrificing supervised operation or fault isolation. For security integrators managing 10–50 access points per site, this kit delivers measurable labor savings and operational reliability.
