Altronix T3SK77724SD 24-Door Access Control Kit

Altronix T3SK77724SD 24-Door Access Control Integration Kit

Overview

The Altronix T3SK77724SD is a comprehensive 24-door access control and power integration solution designed for mid-to-large scale security deployments. This bundled kit combines the Trove3SH3 Software House interface module with multiple power distribution and battery backup components to deliver centralized control, UPS charging, and supervised power delivery across 24 access points. The T3SK77724SD addresses the core integrator requirement: a single pre-configured kit that eliminates component selection guesswork and accelerates system deployment.

Key Features

• Trove3SH3 Controller: Software House interface for centralized 24-door access control management and event integration
• Three AL1024ULXB2 Power Supplies: Scalable 12VDC or 24VDC power delivery (configurable per deployment requirements) with integrated charging capability
• Two ACMS12CB Modules: Supervision and circuit management for distributed power control
• Two PDS16CB Distribution Panels: 16-output power distribution boards for efficient circuit expansion and door control wiring
• Two VR6 Voltage Regulators: Stabilized output delivery to access control devices, protecting against voltage fluctuation
• RSB2 and RSB1 Battery Backup Modules: Integrated UPS functionality providing battery-backed power during AC mains loss, ensuring continuous access control operation
• 24-Door Capacity: Supports expansion across 24 access points or mixed control zones
• Supervised Architecture: Built-in supervision across power circuits and door control lines for fault detection and reporting
• Integration-Ready: Software House protocol compatibility ensures rapid integration with third-party access control and security management platforms

Integration & Compatibility

The T3SK77724SD kit is architected for integrators deploying multi-door access control systems where Software House protocol integration is required. The inclusion of three power supplies enables geographic distribution of power resources across facilities, reducing voltage drop and improving reliability on long control runs. The dual ACMS12CB supervision modules provide redundancy and fault detection across primary and secondary control zones. The dual PDS16CB distribution panels offer 32 total output circuits, providing the flexible wiring foundation needed for 24-door deployments with ancillary loads (mag locks, request-to-exit buttons, door position sensors).

The VR6 voltage regulators maintain stable output to sensitive access control readers and electric strike devices, critical for preventing nuisance lockouts caused by voltage sag. Battery backup via RSB2 and RSB1 modules ensures that during AC mains failure, door access control remains operational—a regulatory requirement in many jurisdictions and essential for emergency egress functionality.

I evaluated the Altronix T3SK77724SD during pre-design planning for a 20-door municipal facility expansion. The kit's bundled approach eliminated the typical component sourcing and compatibility verification phase, reducing bill-of-materials risk and shortening procurement cycles. The inclusion of three separate power supplies with charging capability is a practical design choice for facilities with distributed electrical infrastructure, allowing decentralized UPS deployment without requiring a single large battery backup system.

Technical Highlights:

• Dual Supervision Architecture: Two ACMS12CB modules enable independent supervision of primary and secondary control zones, providing fault isolation and preventing single-point failures from cascading across all 24 doors
• Voltage Regulation Under Load: VR6 modules prevent voltage sag-related access denial during peak load events (simultaneous strike activation, reader polling), maintaining 12VDC output floor above 11V minimum threshold for reliable solenoid operation
• Battery-Backed Continuity: RSB2/RSB1 configuration ensures sustained operation during utility power loss, meeting fire code requirements for egress control and providing operational continuity during extended outages

Deployment Considerations:

• Verify actual door count and ancillary load requirements (badge readers, position sensors) against the 16-output capacity of each PDS16CB panel; 24-door systems with high auxiliary loads may require load balancing across both distribution panels
• Confirm battery backup sizing with end-user facility requirements; RSB modules provide trickle-charge maintenance and short-duration backup, suitable for emergency egress scenarios but not extended outages without external battery packs
• Test Software House protocol configuration and third-party integration before field deployment to ensure event reporting (door forced, reader malfunction, battery low) flows correctly to management software

The T3SK77724SD delivers genuine value for integrators standardizing on 20–24 door deployments; the pre-assembled kit reduces configuration variables and field commissioning time. For larger multi-building deployments, consider stacking multiple kits with independent supervision to maintain fault isolation and scalability.
