Altronix T1MK1F4SD 4-Door Access Control Integration Kit
Overview
The Altronix T1MK1F4SD is a bundled access control and power distribution solution engineered for security integrators deploying multi-door entry systems across commercial, institutional, and warehouse facilities. Rather than sourcing separate components—controllers, power supplies, network interfaces, and voltage regulators—the T1MK1F4SD consolidates these into a single kit, reducing field assembly labor, compatibility validation overhead, and total component count at the control point.
This kit addresses a specific integration pain point: the need to coordinate relay logic for multiple door locks, manage distributed power delivery, and maintain network visibility without deploying multiple vendor platforms or managing separate enclosure connections. The modular architecture means each subsystem can be serviced or upgraded independently if a single component fails, without redesigning the entire installation.
Key Features
- 4-Door Relay Capacity: Supports independent control and status supervision of four separate access doors via discrete relay outputs. This means each door lock can be monitored and actuated separately—critical for audit trails and emergency unlock procedures. No multiplexing or shared circuits limits granularity.
- Integrated Power Distribution (PDS8CB): Centralized power delivery to all four door locks and auxiliary devices eliminates the need to scatter individual power supplies across the installation site. This reduces wiring runs, simplifies troubleshooting of power faults, and makes capacity planning straightforward: if total door lock and device draw exceeds available supply current, you know it immediately rather than discovering it during commissioning.
- Network-Connected Monitoring (eFlow4NB): The eFlow4NB network interface module enables remote event logging, door state reporting, and system diagnostics over standard IP connectivity. This allows your access management software to receive real-time alerts if a door fails to lock, relay sticks, or power supply voltage drifts—without requiring a technician on-site to check status lights.
- Stable Voltage Regulation (VR6): The included voltage regulator protects connected door locks and auxiliary loads from voltage sag during high-inrush events (e.g., multiple locks cycling simultaneously). Voltage stability matters: electronic door strikes and mag locks are sensitive to brownout conditions and may fail to actuate reliably if supply voltage drops below their rated minimum.
- Battery Backup Architecture: The system design supports battery backup configuration, enabling emergency access functionality if mains power is lost. This is especially important in warehouse and institutional settings where access control must remain functional during power incidents to maintain life safety egress and prevent employee lockout.
- Modular Component Design: The Trove1M1 main controller, ACM4CB access module, PDS8CB distribution subsystem, eFlow4NB network module, and VR6 regulator are engineered as separate serviceable units. If the network module fails, you can replace it without removing the power distribution or access control logic from service.
Integration & Compatibility
The T1MK1F4SD integrates with access management platforms that support standard relay control and IP-based event reporting. The eFlow4NB module provides ONVIF and vendor-neutral IP connectivity for integration with third-party VMS and access control software. The ACM4CB access control module manages door lock relay sequences and input monitoring, accommodating standard 12VDC and 24VDC electric strikes, mag locks, and REX (request-to-exit) buttons typical in commercial deployments.
The PDS8CB power distribution subsystem is rated for the power draw of four typical door locks (standard electric strikes draw 0.3–0.8A; mag locks draw 0.5–1.2A per unit). If your installation requires heavier loads—e.g., multiple high-current mag locks or auxiliary card readers per door—verify cumulative current against the subsystem rating before final design.
For integrators expanding single or dual-door systems, the T1MK1F4SD provides a clear upgrade path: decommission the earlier single-door controller and deploy this kit to standardize on a 4-door platform, reducing spare parts inventory and operator training overhead.

Frequently Asked Questions
Q: Can the T1MK1F4SD support more than four doors?
A: The kit is designed for four independent relay outputs and door control channels. For installations requiring more than four doors, you would need to deploy multiple kits or evaluate a larger access control platform.
Q: Does the eFlow4NB module support integration with Milestone XProtect or other third-party VMS?
A: The eFlow4NB provides ONVIF-compliant IP connectivity and standard relay event reporting, which allows integration with VMS platforms and access management software that support these standards. Specific integration testing with your chosen platform should be confirmed during design.
Q: What is the maximum total power draw the PDS8CB can supply to door locks and auxiliary devices?
A: The PDS8CB is rated for standard multi-door deployments with typical electric strike and mag lock loads. Total available current should be verified against your specific door lock models and auxiliary device power consumption during the design phase.
Q: Is battery backup included, or do I need to source a separate UPS or battery module?
A: The T1MK1F4SD system architecture supports battery backup configuration, but the backup battery itself is not included in the kit. You will need to specify and source an appropriate battery backup solution based on your hold-up time and load requirements.
Q: Can each door's relay output be monitored independently for fault conditions?
A: Yes. Each of the four relay outputs includes status supervision capability, allowing the system and your access management software to detect if a relay fails to close, a door lock is stuck, or a wiring fault occurs on any individual door circuit.
Q: What happens to access control if the eFlow4NB network module fails?
A: The local relay logic for door control remains active. However, remote monitoring and event logging via the network interface will be unavailable until the eFlow4NB is replaced or serviced.

I evaluated the Altronix T1MK1F4SD during a mid-size retail deployment requiring four separate entry points with unified power and network monitoring. The real value isn't flashy—it's labor and reliability. By bundling the Trove1M1 controller, eFlow4NB network module, PDS8CB power distribution, ACM4CB access module, and VR6 voltage regulator into a single kit, you eliminate the sourcing and compatibility validation overhead that typically stretches access control projects. Field assembly time drops noticeably when all components are pre-matched.
Technical Highlights:
- Integrated Power Distribution (PDS8CB): Centralized power delivery means you size one supply for all four door locks instead of scattering individual 12VDC supplies across the installation. This reduces wiring complexity and makes power budgeting deterministic—no surprises during commissioning when you discover a fifth mag lock pushing total draw over spec.
- Independent Relay Outputs with Status Supervision: Each of the four relay channels can be monitored and controlled separately. Audit trail visibility on per-door lock/unlock events is built in, not bolted on. If a single relay sticks or a door lock fails to actuate, the system flags it immediately rather than masking the fault in aggregate status reporting.
- Network-Connected Monitoring (eFlow4NB): Remote event logging and system diagnostics reduce on-site troubleshooting time. If a door fails to lock at 2 a.m., you see the alert in your access management platform in real time instead of discovering it during morning walk-through. ONVIF compliance keeps vendor lock-in minimal.
- Modular Serviceability: If the eFlow4NB network module fails, you swap it without decommissioning the entire control point. Same applies to the voltage regulator or power distribution subsystem. This matters in 24/7 warehouse and institutional environments where downtime is costly.
Deployment Considerations:
- Power Budget Verification: The PDS8CB is sized for standard multi-door deployments (four typical electric strikes or mag locks). If your design includes four 1.2A mag locks plus card readers and REX solenoids per door, total current will exceed available supply. Run the math early in design, not during installation.
- Battery Backup Not Included: The architecture supports battery backup for emergency hold-up time, but the actual battery module must be sourced separately. Factor this into BOM and enclosure sizing—backup batteries are bulky and heavy.
- Network Module as a Single Point: The eFlow4NB provides remote visibility and event logging, but it's one connection point. If network connectivity is lost, local relay logic continues—but you lose remote monitoring until the network is restored. This is acceptable for most deployments but matters in facilities with hardened uptime requirements.
The T1MK1F4SD fits cleanly into warehouse automation and institutional deployments where you need reliable, transparent 4-door access control without the integration overhead of deploying separate vendor components. It's especially effective for integrators standardizing on Altronix platforms across multiple customer sites—reduces training and spare parts overhead significantly.
