Altronix TANGO8ACB 8-Output 12VDC Access Power Controller

Altronix TANGO8ACB Access Power Controller

The Altronix TANGO8ACB is an integrated access control power solution designed to manage distributed power delivery for door locks, access readers, and auxiliary devices in multi-door installations. Built into an Altronix BC400 enclosure, the TANGO8ACB combines power distribution, battery backup charging, and PoE-driven input capability, eliminating the need for separate power supplies while maintaining reliable, supervised power to eight independent circuits.

Overview

Access control installations demand redundancy and reliability. The TANGO8ACB centralizes power management for up to eight 12VDC outputs, each independently fused and supervised, making it suitable for mid-scale access control deployments across multiple entry points. The inclusion of a PoE-driven power supply means the controller can operate from a single PoE+ source, simplifying infrastructure while the integrated charger maintains battery backup status for critical failover scenarios. This architecture reduces installation complexity and provides scalable power distribution without requiring dedicated AC circuits at every access point.

Key Features

• Eight supervised 12VDC outputs with independent fused circuits for fault isolation and circuit-level diagnostics
• PoE-driven power supply input for simplified single-source infrastructure delivery
• Integrated battery charger supporting battery backup operation during mains loss
• BC400 form-factor enclosure for wall or rack mounting in security closets and electrical rooms
• Per-output current limiting and supervision capability to detect load faults, short circuits, and device removal
• Modular output design enabling mixed-load configurations across access devices, readers, and auxiliary equipment

Integration & Compatibility

The TANGO8ACB operates as a power hub within standard access control system architectures. Each supervised output supports independent load monitoring and alarm reporting back to access control panels via dry-contact or networked supervision protocols, depending on the host system. The PoE input allows deployment in facilities where PoE+ infrastructure already exists, reducing cabling and power distribution overhead. The unit integrates seamlessly with Altronix battery backup modules and supervision relay packs for expanded alarm and status reporting across multi-door installations.

Package Contents

The TANGO8ACB ships in the BC400 enclosure, pre-assembled and ready for field installation. Verify enclosure contents against your purchase order; additional mounting hardware, backup batteries, and supervision modules are ordered separately based on system design requirements.

Karl Wilson

The Altronix TANGO8ACB represents a straightforward, field-proven approach to multi-door access power distribution. During deployment planning for a recent four-door installation, I evaluated this controller specifically for its supervised output design and PoE-driven input capability, which aligned with our client's existing PoE+ backbone infrastructure.

Technical Highlights:

• Supervised Output Design: Each of the eight 12VDC outputs operates independently with load supervision, enabling per-circuit fault detection and removal alerts without requiring external monitoring relays.
• PoE Power Input: The integrated PoE-driven supply accepts power from a single PoE+ source, eliminating dedicated AC runs to the controller location and reducing infrastructure complexity in retrofit scenarios.
• Battery Backup Integration: The onboard charger supports seamless battery backup module connection, ensuring critical access circuits remain powered during mains outages without controller reboot.

Deployment Considerations:

• Confirm your host access control panel supports the TANGO8ACB's supervision protocol before ordering; supervision integration varies by panel manufacturer and firmware revision.
• For installations requiring more than eight circuits, plan for daisy-chaining multiple TANGO8ACB units on separate PoE+ sources or consolidate loads across fewer outputs with higher per-circuit amperage where device specifications allow.
• Battery backup modules must be sized and ordered separately; verify runtime requirements against expected power draw before final specification.

The TANGO8ACB delivers reliable, granular power management without proprietary complexity. For integrators supporting multiple access platforms, its straightforward supervised output architecture and PoE-driven input make it a practical choice for facilities looking to unify power delivery across distributed door control systems.
