Altronix T1RSH1F4 4-Door Rack Power Controller

Altronix T1RSH1F4 4-Door Access Control Power Integration Kit

Overview

The Altronix T1RSH1F4 is a compact 24-inch rack-mount integration solution designed for multi-door access control deployments requiring consolidated power distribution and relay control. This Trove1R platform kit delivers power conditioning and fail-safe/fail-secure relay management in a single form factor, eliminating the need for separate cabinet installations and reducing overall system footprint. The T1RSH1F4 supports one iStar Edge processor, making it suitable for small-to-medium access control systems requiring centralized wiring management and reliable power backup architecture.

Key Features

• Dual-voltage power supply: 12/24 VDC at 4A output with 115V input for flexible integration into existing facility electrical infrastructure
• Four relay outputs: Independently configurable fail-safe or fail-secure door strike outputs with individual fusing for circuit protection and isolation
• iStar Edge compatibility: Single processor support enables local intelligence and decision-making at the cabinet level
• MM4S module included: Multimode relay module for enhanced input/output flexibility and additional control logic
• Tamper switch: Built-in cabinet-level security monitoring to detect unauthorized access attempts
• Z-bracket external wiring provision: Facilitates clean cable management and field termination without internal chassis routing
• Comprehensive hardware package: All mounting hardware, fasteners, and sub-assemblies included for immediate deployment
• Industry-standard 24-inch rack format: Direct integration into existing server and networking cabinet infrastructure

Integration and Compatibility

The T1RSH1F4 is engineered as a dedicated access control platform supporting Altronix and Software House ecosystem components. Single iStar Edge processor support enables localized access control decision-making, reducing dependency on remote servers for door strike actuation and alarm response. The inclusion of the MM4S module provides additional input/output capacity for integrating supplementary sensors, door position switches, or auxiliary relay logic. Dual power conditioning (12VDC and 24VDC at 4A) accommodates a wide range of electromagnetic lock types, motion sensors, and control devices common in commercial and institutional access systems.

I've evaluated the Altronix T1RSH1F4 during planning for a mid-sized access control retrofit across multiple facility zones. This kit consolidates power distribution and relay control logic in a way that significantly reduces cabinet clutter and simplifies field wiring compared to distributed relay modules.

Technical Highlights:

• Fused relay outputs: Each of the four outputs carries independent fusing, which prevents a single door strike failure from cascading to other doors. This is critical in multi-door environments where a single fault can lock down the entire entrance.
• Dual voltage supply: The 12/24 VDC @ 4A flexibility means you can run both electromagnetic locks and solenoid-based hardware from a single power plant, reducing the need for secondary power supplies.
• iStar Edge integration: Local processor support allows door control decisions to execute at the cabinet without network latency, which improves response time under congestion or WAN outages.

Deployment Considerations:

• Verify that your iStar Edge configuration supports single-processor mode before committing to this form factor; some larger multi-building deployments may require redundant processor architecture.
• The 4A output per voltage rail is appropriate for small-to-medium installations (typically up to four standard electromagnetic strikes). High-current applications may require external power distribution modules.
• Place the tamper switch in an accessible but secure location within the cabinet to ensure monitoring staff can verify alarm conditions during commissioning.

For integrators standardizing on Altronix platforms in smaller branch offices or satellite locations, the T1RSH1F4 delivers reliable, compact power and control without the footprint penalty of larger distributed systems. Specification compliance and fusing architecture are sound.
