Altronix T3M77LCK3D Trove3 Multi-Power Access Control and Camera Power Kit

Overview

The Altronix T3M77LCK3D is a pre-configured, large-format power and access control distribution kit built around the Trove3 wall-mount enclosure. It consolidates dual UL Listed power supplies, multiple PTC-protected distribution boards, an 8-output access control module, and a relay strike board into a single lockable steel housing — the kind of pre-engineered assembly that cuts field wiring time on multi-door, multi-camera commercial deployments where running separate enclosures per power zone is not practical. This kit is listed in the Altronix catalog as the T3MK77L16S/K3 configuration and carries the part number T3M77LCK3D.

The assembly ships as a complete, matched component set. Every board, supply, and mounting bracket is sized for the Trove3 chassis, so there is no retrofitting or custom-cutting — power integration work starts at wiring, not at layout. For integrators managing multi-story access control buildouts or warehouse camera grids, the T3M77LCK3D removes the pre-build engineering step entirely.

Key Features

• Dual AL1024ULXB2 Power Supplies (×2): Two UL Listed 12VDC/24VDC multi-output power supplies with battery backup capability are included, giving the installation redundant or zone-separated power paths. Running two independent supplies inside one enclosure means a single supply fault does not take down all connected devices — critical on multi-door access deployments where lock power loss equals an unsecured door.
• Dual ACMS8CB Access Control Modules (×2): Each ACMS8CB provides 8 individually fused, PTC-protected outputs specifically matched to electric locks and access control readers. Two units in this kit support up to 16 independently protected access control output circuits — enough for an 8-door deployment with readers on every door, all from a single enclosure.
• Dual VR6 Voltage Regulator Boards (×2): The VR6 modules provide regulated, filtered DC outputs for sensitive electronics such as IP cameras and card readers that cannot tolerate supply ripple or voltage sag under load. Including two units gives the installer dedicated regulated rails for cameras separate from the lock power circuits — a best practice that prevents lock-strike inrush from disturbing camera power.
• Dual PDS8CB Power Distribution Strips (×2): Each PDS8CB is an 8-output PTC-protected DC distribution strip with individual circuit breakers. Two units add up to 16 individually protected camera or device circuits — each on its own breaker, so a single shorted run does not pull down the entire zone.
• RSB2 Relay Strike Board (×1): The RSB2 provides 2 relay-switched outputs for controlling electric strikes, magnetic locks, or other switched loads under access control command. Relay outputs handle higher-current strike loads cleanly without routing that current through the panel's logic circuitry.
• Trove3 Enclosure with TM3 Bracket (×1 each): The Trove3 is a large-format, steel, key-locked wall-mount enclosure purpose-built for Altronix Trove-series module stacking. The TM3 bracket mounts inside the Trove3 to support the power supply and distribution boards in their correct mechanical positions. A single lockable enclosure for all power, distribution, and relay hardware satisfies physical security requirements without a custom rack or separate cabinet.
• PTC Overcurrent Protection on All Output Circuits: Polymer positive-temperature-coefficient (PTC) devices on distribution outputs self-reset after a fault clears — no manual re-fusing required. On camera grids with dozens of outputs, this matters: a technician does not need to carry spare fuses or revisit the enclosure after a wiring fault is resolved.

Integration and Compatibility

This kit is designed for deployment within the Altronix Trove ecosystem and is compatible with standard 12VDC and 24VDC access control panels, electric strikes, magnetic locks, and IP cameras operating within the voltage and current ratings of the included AL1024ULXB2 supplies. The ACMS8CB modules interface directly with major access control panel brands. The VR6 regulated outputs are appropriate for PoE-independent IP cameras, intercoms, and card readers requiring clean DC. For camera deployments using PoE switches rather than direct DC feeds, consider pairing this kit with a managed PoE switch for the IP camera layer while using this kit's outputs for access control hardware and analog cameras.

The dual-supply architecture supports zone separation — one AL1024ULXB2 can feed access control hardware while the second powers surveillance devices, keeping the two power domains electrically isolated. Consult the AL1024ULXB2 datasheet for maximum current per output and battery backup sizing guidance before finalizing your load calculations.

For multi-building or campus-scale deployments where a single Trove3 kit is not sufficient, this kit can serve as a zone node in a distributed power architecture. Review the access control system design guide for zone-sizing and power-budget recommendations.

Frequently Asked Questions

Q: What is the T3M77LCK3D, and what does the kit number indicate?

A: The T3M77LCK3D is the catalog part number for the Altronix T3MK77L16S/K3 kit — a pre-configured Trove3 enclosure assembly including dual AL1024ULXB2 power supplies, dual ACMS8CB access control modules, dual VR6 regulator boards, dual PDS8CB distribution strips, and one RSB2 relay board. The kit number encodes the specific module combination Altronix ships as a matched set.

Q: How many access control output circuits does the T3M77LCK3D support?

A: The two ACMS8CB modules provide 8 individually protected outputs each, for a total of 16 access control output circuits. Combined with the two PDS8CB strips (16 additional circuits), the kit can support large multi-door and multi-camera installations from a single enclosure.

Q: Can the T3M77LCK3D power both access control hardware and IP cameras?

A: Yes. The dual AL1024ULXB2 power supplies support zone-separated power feeds — one supply can be dedicated to electric locks and readers via the ACMS8CB modules while the second powers cameras via the VR6 regulated outputs and PDS8CB strips. This separation prevents inrush from lock strikes from affecting camera power stability.

Q: Are the output circuits fused or resettable?

A: The PDS8CB and ACMS8CB modules use PTC (polymer positive-temperature-coefficient) overcurrent protection, which is self-resetting — once a fault clears, the circuit restores automatically without manual re-fusing. The ACMS8CB also includes a circuit breaker for the overall module.

Q: Is battery backup supported in this kit?

A: The AL1024ULXB2 power supplies included in this kit support battery backup. Batteries are not included and must be sourced separately; size them per Altronix's battery backup calculation guidelines based on your total connected load and required backup duration.

Q: Does this kit include the Trove3 enclosure, or do I need to order it separately?

A: The Trove3 enclosure and TM3 mounting bracket are both included in the T3M77LCK3D kit. All components are pre-matched to fit and mount within the Trove3 chassis — no separate enclosure purchase is required.

Eden Phillips

The T3M77LCK3D is one of those kits I recommend when an integrator is scoping an 8-door commercial access buildout and wants to avoid the 'one enclosure per floor' sprawl problem. You're getting two AL1024ULXB2 supplies — both UL Listed with battery backup support — plus dual ACMS8CB modules that deliver 16 total individually PTC-protected access control output circuits, all inside a single lockable Trove3 steel chassis. That's a meaningful reduction in wall penetrations, conduit runs, and inspection surface compared to distributing those same components across multiple smaller enclosures.

Technical Highlights:

• Dual Power Supplies (AL1024ULXB2 ×2): Two independent UL Listed supplies inside one enclosure allow zone-separated power domains — run access control hardware off one supply and surveillance devices off the other, so a lock-strike inrush event does not cause voltage sag on the camera rail.
• 16 PTC-Protected AC Output Circuits (PDS8CB ×2): Each of the two PDS8CB strips provides 8 individually protected DC outputs with self-resetting PTC devices. A shorted camera run pops its own circuit; everything else stays online, and the circuit resets automatically once the fault clears — no truck roll to re-fuse.
• RSB2 Relay Strike Board: The included RSB2 handles 2 relay-switched strike or mag-lock outputs, keeping high-current switched loads out of the panel logic circuitry and reducing contact wear on the access control panel's own relay outputs.

Deployment Considerations:

• Battery backup is supported by the AL1024ULXB2 supplies but batteries are not included in the T3M77LCK3D kit — calculate your load and backup duration before ordering batteries, and verify the Trove3 enclosure has adequate physical space for the battery form factor you select.
• The VR6 regulated output boards are appropriate for voltage-sensitive devices such as card readers and analog cameras, but IP cameras drawing significant current should be load-checked against the VR6's per-output current rating before wiring — do not exceed rated output to avoid thermal limiting.

This kit is well-matched for a mid-to-large commercial office or healthcare facility buildout — specifically the 6-to-10-door access control scenario where consolidating all power hardware into a single IDF-cabinet-level enclosure is both a physical security requirement and a maintenance convenience. It is not the right fit for a 1-or-2-door installation where a single smaller supply and distribution board would be oversized and overpriced.
