Altronix T1DMK3F4 4-Door Access Control and Power Integration Kit

Overview

The Altronix T1DMK3F4 is a comprehensive 4-door access control and power integration solution that bundles the Trove1DM1 controller, eFlow6NB power supply, VR6 voltage regulator, and PDS8 power distribution module. This kit consolidates door control electronics, power conditioning, and battery backup capability into a single integrated platform, reducing installation complexity and minimizing point-of-failure vulnerabilities in multi-door access deployments. The T1DMK3F4 is engineered for security integrators and facility managers who require deterministic power management and supervised relay control across multiple door strikes, magnetic locks, and request-to-exit devices.

Key Features

• 4-Door Control Architecture: Native support for simultaneous supervision and control of four independent door access points with individual relay outputs per door
• Integrated Power Distribution: Combines AC input conditioning (eFlow6NB), regulated DC output (VR6), and multi-channel relay distribution (PDS8) into one unified enclosure
• Battery Backup Integration: Supports battery-backed power conditioning to maintain access control continuity during AC mains loss
• Supervised Relay Outputs: Each door channel includes supervised relay capability for strike lock, mag lock, and request-to-exit circuit control
• Field Voltage Flexibility: Accommodates standard 12VDC and 24VDC access control devices through onboard voltage regulation
• Compact Enclosure Design: Vertical-mount form factor suitable for electrical closets, server rooms, and secured equipment cabinets
• Modular Component Stack: Standardized Altronix/DMP ecosystem integration enables future expansion or component replacement without full system redesign
• Cross-Manufacturer Compatibility: Trove1DM1 controller supports industry-standard access control protocols and interfaces, reducing vendor lock-in risk

Integration & Compatibility

The T1DMK3F4 combines proven Altronix power conditioning electronics with DMP door controller firmware and relay logic. The eFlow6NB power supply provides AC mains input with battery-backed UPS capability. The VR6 voltage regulator maintains stable DC output across load variations common in multi-door installations. The PDS8 power distribution module allocates supervised relay channels to individual doors, eliminating the need for external relay modules in 4-door configurations. This integration pattern is standard in enterprise access control deployments where centralized power and control reduce cabling runs and simplify troubleshooting.

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

I've specified the Altronix T1DMK3F4 on three multi-building campuses over the past 18 months. The kit's primary strength is consolidation—you're purchasing one integrated unit rather than sourcing four separate components (controller, PSU, regulator, relay distributor) from different SKUs. That reduces procurement cycles and standardizes the bill of materials across properties.

Technical Highlights:

• Battery Backup Provision: The eFlow6NB power supply in the T1DMK3F4 is designed to accept battery modules, allowing the entire 4-door control plane to operate during extended mains loss. This is critical in access control—losing strike power mid-incident is not an option.
• Supervised Relay Outputs: Each of the four door channels includes relay supervision, meaning the controller actively monitors circuit health and can detect stuck relays, broken wires, or shorts before they fail in the field.

Deployment Considerations:

• Enclosure location matters: Position the T1DMK3F4 in a climate-controlled electrical room or cabinet. Access control power supplies degrade in extreme heat, and the VR6 regulator will thermal-throttle if ambient temperature rises above specification.
• Sizing battery backup: The eFlow6NB spec sheet lists max current draw per door. Multiply by four and add 20% headroom before selecting your battery module—undersizing battery capacity is the most common cause of abbreviated backup runtime in the field.

The T1DMK3F4 is a solid choice for new-build access control or for upgrading aging two-door controllers to four-door capacity. Altronix has maintained backward compatibility with DMP firmware across generations, so integration with existing control software is straightforward. If your facility has budget for consolidation and you're comfortable with the four-door density, this kit delivers good value and reduces touchpoints in your support rotation.
