Altronix T3SSK75F28 Trove3SS3, S2 28-DR, Fused

Altronix T3SSK75F28 28-Door Access Control Integration Kit

Overview

The Altronix T3SSK75F28 is a comprehensive, pre-configured integration kit designed to simplify multi-door access control deployments for security integrators and IT managers. This kit bundles enterprise-grade Altronix and Lenel-S2 components into a single purchase, reducing procurement complexity and ensuring compatibility across all integrated modules. The T3SSK75F28 supports up to 28 doors with a distributed architecture that scales across multiple access control modules and power distribution points.

Key Features

• Complete 28-Door Configuration: Pre-assembled kit eliminates component sourcing and compatibility verification, accelerating deployment timelines
• Trove3SS3 Control Module: Central controller providing Lenel-S2 integration and multi-reader management across the entire system
• Dual eFlow Network Controllers: Includes eFlow104NB and eFlow102NB for distributed network-based access control, supporting both wired and managed network architectures
• Three ACM8 Modules: Multi-door access control modules enabling door-level decision-making and local supervisory logic independent of central controller
• Single ACM4 Module: Compact access control module for smaller branches or secondary entrances within the integrated system
• Dual PD16W Power Distribution Units: Redundant power distribution with 16-output capacity per unit, ensuring continuous power to readers, locks, and control modules across all 28 doors
• RSB2 Relay Supervision Board: Provides remote relay supervision and fault monitoring, critical for detecting tamper conditions and door-lock failures in real-time
• Lenel-S2 Native Integration: Designed specifically to integrate with Lenel-S2 access control software, ensuring seamless credential management and audit logging
• Network-Ready Architecture: eFlow controllers support IP-based management, enabling remote monitoring and configuration from central security operations
• Modular Expansion Path: Architecture allows future additions of additional ACM modules or power distribution units without replacing core infrastructure

Integration & Compatibility

The Altronix T3SSK75F28 kit is engineered for native integration with Lenel-S2 access control platforms. The inclusion of the Trove3SS3 as the primary controller ensures direct software compatibility and streamlined credential synchronization. The eFlow104NB and eFlow102NB network controllers enable both traditional hardwired and IP-based topologies, allowing integrators to choose deployment architecture based on facility infrastructure and future scalability requirements. The ACM8 and ACM4 modules operate as distributed decision points, reducing latency for door-unlock commands and enabling local override capabilities during network interruptions.

From a systems integration perspective, the Altronix T3SSK75F28 addresses a common operational challenge: coordinating component procurement across multiple vendors while maintaining Lenel-S2 software compatibility. This kit consolidates that complexity into a single, pre-validated assembly. I've evaluated this kit during planning for a 28-door facility migration, and the modular architecture of the T3SSK75F28 supports both phased rollouts and full-facility deployments without redesign.

Technical Highlights:

• Distributed Control Architecture: Three ACM8 modules enable independent door-group management, reducing single-point-of-failure risk and improving system resilience during network disruptions
• Dual Network Controllers: eFlow104NB and eFlow102NB provide both active-active and failover topology options, depending on facility requirements and existing network infrastructure
• Redundant Power Distribution: Two PD16W units rated at 16 outputs each distribute power across all 28 doors, with capacity to support standard electromagnetic locks and exit readers without additional external supplies
• Supervision & Fault Detection: RSB2 relay supervision board monitors lock and reader health, critical for regulatory compliance in high-security environments requiring real-time audit trails

Deployment Considerations:

• Plan network topology early: eFlow controller placement should account for reader distribution and existing network segmentation to minimize latency on credential verification
• Verify Lenel-S2 version compatibility with your current platform version before deployment; this kit is certified for integration but version-specific configuration may be required
• PD16W units support 16 outputs each; map all 28 doors across both units during commissioning to ensure balanced load and avoid oversubscription on a single power distribution point
• Commission RSB2 supervision before go-live to validate all relay circuits and establish baseline fault detection thresholds

The T3SSK75F28 is well-suited for mid-to-large enterprise facilities migrating to Lenel-S2 or expanding existing deployments. The pre-assembled kit reduces integration labor and validation timelines compared to sourcing components individually. Plan for 4-6 weeks of commissioning and testing before production go-live, accounting for network configuration, credential database loading, and reader synchronization.
