Altronix T2SSK7F8 8-Door Access Control & Power Integration Kit
Overview
The Altronix T2SSK7F8 is a complete 8-door access control and power management solution engineered for mid-scale security deployments where independent door control, real-time event reporting, and centralized power supervision matter. This kit bundles the Trove2SS2 access control processor, eFlow104NB power module with battery backup, ACM8 8-channel control interface, VR6 voltage regulator, PDS8 power distribution system, and RSB1 relay supervision module — all pre-configured to work as a single platform under Lenel-S2 access control software. For integrators and facility managers running 4–8 doors across a single building or campus zone, the T2SSK7F8 eliminates the complexity of mixing standalone door controllers and disconnected power supplies by consolidating access logic, power budgeting, and circuit monitoring into one enclosure.
Key Features
- 8-Door Independent Control: Each of the eight doors operates on its own access control circuit, so one jammed door or failed reader doesn't cascade into facility-wide lockout. You get per-door status reporting and troubleshooting visibility.
- Lenel-S2 Native Integration: The Trove2SS2 controller communicates directly with Lenel-S2 platform modules, meaning credential updates, access policy changes, and access attempt logging flow in real time without polling delays or middleware translation layers. Deploy faster and reduce integration risk.
- eFlow104NB Power Module with Battery Backup: Delivers 24VDC regulated output with integrated UPS charging and supervision. During mains power loss, battery-backed circuits keep doors in fail-secure or fail-safe state (your choice per door) and support emergency egress override without a separate battery cabinet. Reduces rack footprint and wiring labor.
- ACM8 8-Channel Access Control Interface: Each channel independently manages electric strikes, magnetic locks, request-to-exit sensors, and door position switches. Supervision circuits detect tamper attempts or sensor disconnection, triggering real-time alerts rather than silent failures.
- VR6 Voltage Regulator: Stabilizes 24VDC output across all eight door circuits, preventing voltage sag that would cause credential readers to drop offline or mag locks to release unexpectedly under load. Especially important in installations where multiple doors are accessed simultaneously.
- PDS8 8-Output Power Distribution System: Each door gets its own fused power channel with individual status indication. If door 3's strike fails, door 7 still operates normally. Fusing prevents cascade failures and makes isolation troubleshooting straightforward — swap a single 24VDC fuse rather than power down the entire system.
- RSB1 Relay Supervision Module: Continuously monitors relay contacts for mechanical wear, contact corrosion, or circuit faults. Real-time reporting alerts you to pending maintenance before a relay fails silently, avoiding unplanned downtime during business hours.
- Unified Event Logging: All eight doors report credential attempts, access grants, denials, door position changes, and power faults to a single audit trail. Simplifies compliance investigations and post-incident forensics.
- Wall or DIN-Rail Mounting: Kit components fit standard electrical enclosures, allowing installation alongside existing HVAC, fire, or building automation panels without dedicated access-control-only cabinets.
- Emergency Egress Support: Battery-backed circuits enable automatic door unlock on mains power loss (configurable per door) plus manual override capability, so occupants never face a dead-locked exit during an outage.
Integration and Compatibility
The T2SSK7F8 is purpose-built for Lenel-S2 environments and does not integrate with competing access control platforms. The Trove2SS2 processor expects native S2 credential formats, policy rules, and database structures. If your facility uses Genetec, Salto, Paxton, or other non-Lenel platforms, this kit is not the right fit. For Lenel-S2 deployments, the kit eliminates the need to source power supplies, distribution panels, and relay modules separately — all critical components are bundled, tested, and pre-wired. The ACM8 module provides eight isolated door circuits, each rated for standard 24VDC solenoid loads (electric strikes, mag locks). Heavy-draw accessories such as turnstiles or bollards may require external relay modules and should be reviewed with the system designer. The eFlow104NB power module includes supervised battery charging, so backup battery capacity (typically a 12Ah or 24Ah 24VDC sealed lead-acid unit purchased separately) can be added without additional charger circuitry. The VR6 regulator maintains output voltage stability under transient load changes, reducing credential reader dropouts during multi-door access events. The PDS8 distribution system isolates each door's power with individual 2A fuses, rated for standard electromagnetic strike and mag-lock solenoid currents; over-current faults trigger immediate circuit isolation and status indication on the panel.

Frequently Asked Questions
Q: Is the Altronix T2SSK7F8 compatible with access control platforms other than Lenel-S2?
A: No. The Trove2SS2 processor is designed exclusively for Lenel-S2 integration. If your facility uses Genetec, Salto, Paxton, or another non-Lenel platform, you will need a different access control kit.
Q: What happens to the doors if mains power is lost?
A: The eFlow104NB module includes battery backup with supervised charging. During a power loss, battery-backed circuits keep doors in either fail-secure (locked) or fail-safe (unlocked) state based on your per-door configuration. An automatic egress override ensures emergency exits unlock, and manual override buttons allow authorized personnel to unlock specific doors if needed.
Q: Can I expand the kit to control more than eight doors?
A: The T2SSK7F8 is fixed at eight doors. For larger deployments, consult with your Lenel-S2 system integrator about daisy-chaining additional eight-door modules or using larger centralized controllers.
Q: Do I need to purchase a separate battery for backup power?
A: Yes. The eFlow104NB module includes the charger and supervision circuitry, but the actual backup battery (typically a 12Ah or 24Ah 24VDC sealed lead-acid unit) must be purchased separately and connected to the module's battery terminals.
Q: What happens if a door's power circuit exceeds the fuse rating?
A: The PDS8 power distribution system includes individual 2A fuses for each door circuit. If a door's load (strike, mag lock, reader) draws more than 2A, the fuse will open, isolating that door's power and lighting an indicator on the panel. This prevents the power failure from affecting other doors. Verify that your selected strike and reader hardware draw under 2A per door during peak operation.
Q: Can I use the T2SSK7F8 outdoors?
A: The T2SSK7F8 is designed for indoor enclosure installation (wall or DIN-rail mounted in an electrical cabinet). Outdoor deployment would require a weatherproof electrical enclosure and field-hardened connection hardware, which must be specified separately.

The Altronix T2SSK7F8 is a solid middle-ground choice for Lenel-S2 shops running 4–8 doors in a single facility or campus zone. The bundle structure — combining the Trove2SS2 processor, eFlow104NB power module with supervised battery charging, and the PDS8 8-output distribution system into one kit — eliminates the guesswork of mixing standalone components. You're not jury-rigging a generic 24VDC supply into an access control setup; the T2SSK7F8 is purpose-built for this exact use case.
Technical Highlights:
- eFlow104NB Battery-Backed Power Module: Includes supervised charging and UPS capability, so backup battery capacity (purchased separately) integrates without extra charger boards or external relay supervision. During mains loss, the module maintains 24VDC to all eight door circuits while the RSB1 relay supervision module logs the outage in real time. This design reduces enclosure clutter and simplifies commissioning.
- PDS8 8-Output Isolation with Per-Door Fusing: Each door gets its own 2A fuse and status indicator. If a strike solenoid shorts or a reader draws excessive current on door 3, only that circuit opens — doors 1, 2, 4–8 remain powered. Troubleshooting becomes surgical rather than facility-wide panic. Verify your strike and reader hardware draw under 2A per door under peak load before installation.
- VR6 Voltage Regulation Across All Eight Channels: Stabilized 24VDC output prevents credential reader dropouts during simultaneous multi-door access events. In high-load scenarios (simultaneous badge swipes at multiple doors during shift change), voltage regulation keeps readers responsive. Without this, early-generation access control kits would see readers flake out under sustained load.
Deployment Considerations:
- Lenel-S2 Only: The Trove2SS2 processor will not interoperate with Genetec, Salto, Paxton, or other non-Lenel platforms. Verify your facility's VMS and access control stack before purchasing. If you're migrating to Lenel-S2, this kit accelerates deployment; if you're locked into another platform, keep shopping.
- Per-Door Load Budget: The PDS8 individual fusing is a feature, not a limitation, but it enforces a discipline: each door's strike, mag lock, and reader combination must total under 2A. High-draw accessory loads (turnstiles, bollards, dual-solenoid strikes) may exceed this and require external relay modules — confirm with your hardware vendor during design review.
Deploy the T2SSK7F8 in Lenel-S2 environments where you need clean power distribution, per-door circuit isolation, and battery-backed egress across 4–8 doors. For single-door quick-installs or 20+ door campuses, look elsewhere. For a medium-scale Lenel shop that wants to skip the component sourcing and integration labor, this kit pays for itself in setup time alone.
