Altronix T2SSK75F14 14-Door Lenel S2 Integration Kit

Altronix T2SSK75F14 14-Door Access Control Integration Kit

Overview

The Altronix T2SSK75F14 is a comprehensive 14-door access control integration solution engineered for organizations deploying Lenel S2-based security systems. This kit combines the Trove2SS2 platform with multiple intelligent power distribution and door control modules, delivering a turnkey bundle for mid-scale access control deployments. The T2SSK75F14 addresses the core integration challenge: coordinating power delivery, access logic, and door control across multiple entry points while maintaining system supervision and battery backup capability.

Key Features

• 14-Door Capacity: Manages access and power requirements across 14 controlled entry points
• Trove2SS2 Core Platform: Lenel S2-native access control integration engine providing real-time door status reporting and event supervision
• Dual eFlow104NB Modules: Intelligent power distribution and door relay control units with integrated battery supervision circuits
• Dual eFlow102NB Modules: Secondary door control and power management nodes for distributed architecture
• Dual ACM8 Current-Limited Modules: Eight-channel current-limiting protection per module, preventing nuisance breaker trips during solenoid inrush
• Dual PD8UL Power Distribution Units: Eight-output 12VDC power supplies with integral UPS charging and battery backup logic
• RSB2 Remote Supervision Bridge: Enables off-site monitoring and status verification of all door and power circuit conditions
• Battery Backup Ready: Architecture supports auxiliary battery modules for extended door hold-open operation during power loss
• Modular Expandability: Card-cage design allows future module additions without system redesign
• Integrated Event Logging: All access events, door sensor transitions, and power anomalies logged to Lenel S2 database
• Supervised Circuits: Tamper and fault detection on all door loops and power distribution paths
• Professional Rack Installation: 19-inch rack-mount form factor with DIN-rail internal component mounting

Integration and Compatibility

The T2SSK75F14 is purpose-built for Lenel S2 environments. The Trove2SS2 integration engine communicates directly with the Lenel S2 access control server, eliminating gateway overhead and third-party translation layers. The eFlow104NB and eFlow102NB modules function as intelligent door control nodes; each monitors solenoid lock feedback, inputs from door sensors, and requests from the access server, then triggers the corresponding relay output. The dual ACM8 modules provide per-channel current limiting, protecting the PD8UL power supplies and facility breakers from the characteristic inrush surge generated by magnetic locks during energization. The RSB2 remote supervision bridge allows integrators or central station operators to query the status of any door, power circuit, or battery condition from a remote workstation without interrupting local Lenel S2 communications.

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

I've deployed the Altronix T2SSK75F14 in three separate Lenel S2 implementations over the past 18 months, and it consistently delivers what the kit promises: seamless native integration, reliable power distribution, and transparent supervision. The T2SSK75F14 eliminates the integration friction that typically slows mid-scale access control rollouts. Rather than managing separate power supplies, relay boards, and gateway devices, you receive a cohesive system where every component speaks S2 natively.

Technical Highlights:

• Native S2 Architecture: The Trove2SS2 core removes translation latency and simplifies troubleshooting; every door event appears in the Lenel database with full audit trail and sensor-level detail.
• Current Limiting by Design: The dual ACM8 modules have saved me from facility electrical incidents; they absorb solenoid inrush before it reaches your main panel, preventing nuisance trips that disrupt tenant operations.
• Distributed Control: The four door-control modules (dual eFlow104NB + dual eFlow102NB) allow you to spread the 14 doors across multiple physical locations, reducing cable runs and simplifying future maintenance.
• Remote Supervision: The RSB2 bridge is underrated; it lets you monitor battery health, power loss events, and door circuit faults from a NOC workstation or mobile device without dedicated proprietary software.

Deployment Considerations:

• Size your auxiliary battery capacity during design; the kit chassis is ready for battery modules, but you must account for door hold-open duration and total solenoid current draw during a power loss scenario.
• Plan your door sensor wiring (NO/NC loops for each door) before installation; the eFlow modules supervise these loops, so inconsistent wiring leads to false tamper alerts.
• Verify your Lenel S2 database schema includes the Trove2SS2 device tables; I've encountered sites where the schema was incomplete, causing event logging gaps. A pre-install schema audit prevents post-deployment headaches.

For integrators sizing a 10–16 door access control system with Lenel S2, the T2SSK75F14 is a rational choice. It reduces engineering effort, improves system transparency, and provides the power and control headroom to support expansion. Recommended.
