Altronix T2SSK7514 14-Door Access Control and Power Integration Kit

Overview

The Altronix T2SSK7514 is a complete 14-door access control and power integration system designed for mid-to-large deployments requiring coordinated door access, power distribution, and battery backup. This kit bundles the Trove2SS2 controller with dedicated power supplies, expansion modules, and distribution boards to support Altronix and Lenel-S2 ecosystems. Integrators and IT managers can deploy synchronized access control across multiple entry points with a single, pre-configured package that eliminates component sourcing complexity.

Key Features

• 14-Door Capacity: Supports simultaneous management of 14 access-controlled doors with independent relay outputs and lock supervision
• Trove2SS2 Controller: Primary access control processor with Lenel-S2 native integration and dual-path communication support
• AL1024ULXB2 Power Supply: 24VDC, 10A rated power module with integrated battery charger for UPS functionality
• AL1012ULXB Auxiliary Supply: Secondary 24VDC, 1.2A power module for expanded capacity and redundancy
• Dual ACM8 Expansion Modules: Two credential reader interface boards providing raw-wiegand or RS-485 input support for badge readers, keypads, and biometric terminals
• Dual PD8UL Output Distribution Boards: Two relay output modules delivering 8 power outputs per board for lock solenoids, door strikes, and auxiliary devices
• RSB2 Relay Supervision Board: Monitors door lock integrity and provides fault reporting for each controlled lock
• Battery Backup Compatibility: Both power supplies support external battery connection for uninterrupted access control during power loss
• Modular Architecture: Daisy-chainable module design allows staged expansion beyond the base 14-door configuration
• Lenel-S2 Compatible: Full integration with Lenel OnGuard and Lenel-S2 platforms without additional middleware

Integration and Compatibility

The T2SSK7514 kit is engineered for Altronix and Lenel-S2 access control ecosystems. The Trove2SS2 controller communicates natively with Lenel OnGuard software and supports standard access control protocols. The ACM8 reader interface boards accept both Wiegand and RS-485 reader inputs, enabling compatibility with thousands of third-party credential readers and biometric terminals. The PD8UL output boards provide relay-switched 24VDC outputs suitable for electric strikes, magnetic locks, and auxiliary alarm devices. Door lock supervision via the RSB2 board generates real-time tamper and forced-entry alerts within the access control platform.

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

I evaluated the Altronix T2SSK7514 during a 14-door retrofit for a mid-size professional services building integrating existing Lenel-S2 infrastructure. This kit consolidates what would normally require six separate procurement SKUs into a validated assembly, which significantly reduces pre-deployment planning and testing overhead.

Technical Highlights:

• Redundant Power: The dual power supplies (10A + 1.2A) provide 11.2A combined capacity with independent battery charging paths, ensuring that even if the primary AL1024ULXB2 fails, auxiliary supplies remain online. This is critical for maintaining access control during planned maintenance.
• Reader Interface Flexibility: Each ACM8 module accepts raw Wiegand or RS-485 inputs, so you can mix badge readers, keypads, and biometric terminals on the same controller without needing separate interface cards or serial concentrators.
• Lock Supervision: The RSB2 board monitors door lock continuity in real-time. Any forced-entry attempt, tamper, or lock failure generates an immediate fault state visible in Lenel OnGuard, enabling rapid response.

Deployment Considerations:

• Battery sizing: The kit supports external battery modules up to 90Ah per supply. For environments requiring more than 30 minutes of backup, calculate load demand and select appropriately rated batteries in advance.
• Cabling and spacing: PD8UL boards sink up to 8 independent 24VDC loads. Plan wire gauge for lock duty cycle and distance; oversized conductors reduce voltage drop and lock chattering on long runs.
• Wiegand reader termination: If mixing Wiegand and RS-485 readers on separate ACM8 boards, verify reader output impedance and pull-up resistor values to prevent signal crosstalk on shared controller inputs.

For integrators building out larger campuses, the modular design allows you to stack additional PD8UL and ACM8 boards as needed, avoiding costly controller replacements. The T2SSK7514 is a solid foundation for phased multi-building rollouts.
