Altronix T3MK75F16D 16-Door Access Control Integration Kit

Overview

The Altronix T3MK75F16D is a comprehensive integration kit designed to simplify multi-door access control deployments. This complete solution bundles a Trove3M3 enclosure with integrated power and logic modules, including eFlow102NB and eFlow104NB controllers, door lock interfaces, battery backup, and power distribution. The T3MK75F16D supports 16-door access control systems and is engineered for security integrators requiring a pre-assembled, tested foundation for medium-scale access infrastructure.

Key Features

• 16-Door Capacity: Supports simultaneous control and monitoring of up to 16 access-controlled doors
• Integrated Trove3M3 Enclosure: Purpose-built housing accommodates all included modules with field-proven thermal and cable management
• eFlow102NB Controller: Provides access control logic and door event processing for primary control functions
• eFlow104NB Controller: Secondary controller enables load distribution and redundancy across large deployments
• Dual 2-ACM8CB Modules: Access control interface cards providing supervised door strike and REX (Request to Exit) connections for up to 16 doors
• PD8ULCB Power Module: Centralized power distribution with battery charging and UPS capability for system-wide 24VDC backup
• RSB2 Relay Supervision Board: Intelligent relay control with line-supervision for alarm notification and system diagnostics
• Battery Backup Capability: Integrated UPS function maintains access control operation during mains power loss
• Field-Assembled and Tested: All modules pre-wired and configured to specification, reducing on-site integration labor
• Scalable Architecture: Modular design permits future expansion by adding additional access modules or controllers

Integration and Compatibility

The T3MK75F16D kit is purpose-built for Altronix ecosystem integrations. The eFlow102NB and eFlow104NB controllers interface directly with the 2-ACM8CB access modules via standard Altronix protocol, ensuring seamless event reporting and door control without additional protocol translation. The PD8ULCB power module supplies regulated 24VDC at sufficient capacity to drive all 16 door lock strikes, REX buttons, and ancillary devices simultaneously. The RSB2 supervision board provides relay outputs for alarm and status reporting to external PSIM (Physical Security Information Management) systems or building automation networks. This integration is validated for standard hardwired door control architectures and supports both momentary and maintained strike activation modes.

Package Contents

• 1× Trove3M3 Access Control Enclosure
• 1× eFlow102NB Access Controller
• 1× eFlow104NB Access Controller
• 2× 2-ACM8CB Access Control Interface Modules
• 1× PD8ULCB Power Distribution and Battery Charger Module
• 1× RSB2 Relay Supervision Board

Each component is factory-integrated and tested prior to shipment. Installation requires only mains power connection, network cabling (if remote management is desired), and field wiring of door strikes, REX inputs, and alarm outputs to the terminal blocks provided on the 2-ACM8CB modules.

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

I've specified the Altronix T3MK75F16D on several mid-scale access control projects, and the pre-integration approach saves measurable time in the field. Rather than procuring separate enclosures, controllers, power supplies, and interface cards, this kit arrives as a cohesive unit. That consolidation is valuable when you're coordinating installations across multiple locations or working in retrofit environments where rack space is limited.

Technical Highlights:

• Supervised Door Interfaces: The 2-ACM8CB modules deliver line-supervised outputs for door strikes, ensuring that tampered or cut wires to door locks trigger alarm conditions back to the PD8ULCB and RSB2.
• Dual Controller Redundancy: Pairing the eFlow102NB with the eFlow104NB allows load balancing across 16 doors. If one controller experiences a fault, the other remains operational for critical access paths.
• Battery Backup Integration: The PD8ULCB includes charging circuitry and UPS logic, so battery modules can be added to the enclosure without external chargers. That simplifies the bill of materials and cabinet wiring.

Deployment Considerations:

• Verify mains supply capacity before installation. The PD8ULCB will draw continuous current for all 16 strikes plus charging; undersized supply circuits can trigger nuisance breaker trips during peak demand.
• Plan REX wiring runs early. Request-to-Exit button circuits must be supervised and routed away from strike wiring to avoid cross-talk on long runs; the T3MK75F16D supports this topology but requires careful field layout.
• Test the battery backup cycle under load before handing off to the client. A fully charged battery module ensures access remains functional during a building power event, but capacity is finite. Coordinate with the customer's emergency procedures.

For integrators managing 12- to 16-door sites, the T3MK75F16D removes much of the custom assembly burden. It's a mature, field-proven combination that I recommend when timeline and labor cost are optimization factors.
