Altronix T2MK5F8 Access Control Power Distribution Kit with Battery Backup

The Altronix T2MK5F8 is a UL294-listed, 12VDC/10A power distribution kit designed for commercial access control and surveillance installations that need clean, fused, battery-backed power across multiple field devices. Combining the TROVE2M2 enclosure, TMV2 power supply, and an integrated 12AH backup battery, the T2MK5F8 packages what would otherwise be three separate line items into a single, pre-assembled unit — reducing installation time and simplifying code-compliant commissioning on door controllers, readers, electric strikes, and camera runs.

Overview

Centralized access control power is one of those infrastructure decisions that shows up in every service call and every inspection. The T2MK5F8 is built around that reality: one enclosure, one AC input, one battery connection, and eight individually fused 12VDC outputs ready to terminate. The TROVE2M2 enclosure is sized at 27.25" × 21.5" × 6.5" — large enough to accommodate field wiring and the 12AH battery without crowding, and deep enough to keep conduit entries organized. At 39.6 lb. fully assembled, it wall-mounts as a fixed installation rather than a rack panel, which suits IDF closets, electric rooms, and above-ceiling control spaces in commercial buildings.

The Altronix power supply line is purpose-engineered for physical security infrastructure, and the TMV2 module inside this kit reflects that: UL294 listed for access control power, cUL listed to CAN/ULC-S319-05 for Canadian installations, and CE marked for European Conformity. If your project spec requires agency-listed power on the access control circuit — and most commercial projects do — this unit checks that box without requiring a separate variance or field-engineering workaround.

Key Features

• 12VDC @ 10A Regulated Output: Ten amps at 12 volts gives you meaningful headroom across eight outputs — enough to run a multi-reader door controller, several electric strikes, and a couple of IP cameras on the same distribution point without approaching the supply's ceiling. Load budget each output against your device draw; the 3.5A/250V per-output fusing protects downstream devices and prevents one failed load from collapsing the bus.
• Eight Individually Fused Outputs (3.5A/250V each): Fused distribution at the output level means a shorted field device blows its own fuse without interrupting power to the remaining seven circuits. On a 20-door access system where every output feeds a critical entry point, that fault isolation is the difference between one door going down and an entire wing losing power during a live event.
• Integrated 12VDC/12AH Battery Backup: The onboard 12AH battery sustains connected loads through AC outages — essential for UL294-compliant access control installations where continuity of egress hardware is a code requirement. Runtime depends on total connected draw; lighter loads (readers, low-current strikes) will see substantially longer backup windows than full-load deployments.
• 120VAC/60Hz Input with 5A/250V Input Fusing: Standard North American single-phase AC input means no step-down transformer or special circuit required — connect to a standard 15A or 20A branch circuit. The 5A input fuse provides upstream protection for the power supply module itself.
• UL294 Listed: UL294 is the access control power equipment standard required by most AHJs and commercial specs. Listing to this standard means the T2MK5F8 has been independently tested for performance and safety in access control applications — not just a generic power supply repurposed for the job. The cUL listing (CAN/ULC-S319-05) extends that compliance to Canadian projects.
• Operating Range 0°C to 49°C: Covers IDF closet and electrical room environments where temperatures can climb, but does not qualify for unheated exterior enclosures in cold climates. Plan accordingly if you're deploying in a space that drops below freezing in winter.
• TROVE2M2 Enclosure: The TROVE series enclosure provides a dedicated mounting surface for the TMV2 module and battery with pre-punched knockouts for conduit entry. Cabinet organization matters on high-density access installs — field techs pulling wire to 8 outputs need room to terminate and label cleanly, and the TROVE2M2 is sized to allow it without stacking cables.

Integration & Compatibility

The T2MK5F8 fits naturally into any 12VDC access control or surveillance camera infrastructure. Compatible downstream devices include electric strikes (both fail-safe and fail-secure rated within output current limits), electromagnetic locks, door controllers, card readers, request-to-exit sensors, and 12VDC-input IP cameras that aren't PoE-powered. Pair with an access control panel and your preferred reader technology — the power supply is agnostic to reader protocol and controller brand.

For larger deployments requiring more outputs or higher aggregate current, Altronix's broader power supply family includes 16-output and higher-amperage variants. The T2MK5F8 is the right scope for single-floor or single-zone deployments of roughly 4–8 doors where all loads live within practical cable run distance of a single enclosure.

Frequently Asked Questions

Q: What is the UL listing for the T2MK5F8, and what does it cover?

A: The T2MK5F8 is UL294 listed, which is the standard for access control system power equipment. It is also cUL listed to CAN/ULC-S319-05 for Canadian installations and CE marked for European Conformity. UL294 listing is the requirement most commercial AHJs and project specs cite for access control power sources.

Q: How many devices can the T2MK5F8 power simultaneously?

A: The T2MK5F8 provides eight individually fused 12VDC outputs. Each output is protected by a 3.5A/250V fuse. The total supply current is 10A at 12VDC, so the combined draw across all eight outputs must not exceed 10A. Budget each output individually against your device's rated current draw.

Q: What battery does the T2MK5F8 use, and how long will it run on backup power?

A: The T2MK5F8 integrates a 12VDC/12AH sealed lead-acid battery. Runtime depends entirely on the total current draw of connected devices. Lightly loaded installations (readers and low-current strikes) will sustain longer backup windows than fully loaded deployments. Calculate: backup hours ≈ 12AH ÷ total load in amps.

Q: Can the T2MK5F8 be used in outdoor or unheated enclosures?

A: The T2MK5F8 is rated for 0°C to 49°C operating temperature. This covers conditioned and semi-conditioned interior spaces such as IDF closets and electrical rooms, but does not qualify for unheated outdoor or exterior enclosures in climates where temperatures fall below freezing. The storage temperature range extends to -20°C to 70°C.

Q: What are the physical dimensions and weight of the T2MK5F8?

A: The assembled T2MK5F8 measures 27.25" × 21.5" × 6.5" (W × H × D) and weighs 39.6 lb. Plan for two-person installation and ensure your mounting surface can support the weight, particularly with the 12AH battery installed.

Q: Does the T2MK5F8 support Canadian and European projects?

A: Yes. The T2MK5F8 carries cUL listing to CAN/ULC-S319-05 for Canadian installations and CE marking for European Conformity, in addition to its primary UL294 listing for U.S. projects.

The T2MK5F8 is a unit I recommend specifically when an integrator needs a UL294-listed, battery-backed power solution in a single wall-mount package and doesn't want to engineer the enclosure, supply module, and battery as three separate BOM line items. The 10A aggregate at 12VDC with eight fused outputs is a solid match for a 4–6 door access zone, and the 12AH battery keeps the math simple for AHJ backup-time documentation.

Technical Highlights:

• UL294 + cUL Dual Listing: Both U.S. and Canadian code compliance from a single SKU — no variant sourcing for cross-border commercial projects. The CAN/ULC-S319-05 cUL listing is frequently overlooked until the AHJ inspection, and finding out at that point is expensive.
• 8 × 3.5A Fused Outputs: Per-output fusing at 3.5A means a shorted strike or reader on one circuit doesn't collapse the entire distribution bus. On a live commercial site, that isolation is the spec that keeps a service call from becoming a security incident.
• 0°C to 49°C Operating Range: Covers virtually every conditioned mechanical and electrical room scenario, but this ceiling matters — a non-climate-controlled exterior closet in summer in the American Southwest can easily exceed 49°C, which puts this unit out of spec. Verify the install location before specifying.

Deployment Considerations:

• At 39.6 lb. with the 12AH battery installed, this is a two-person wall mount. Factor that into your labor estimate, particularly in overhead or tight-space installations where maneuvering a 40 lb. enclosure requires staging.
• The 5A input fuse on the 120VAC side means you need a clean, dedicated branch circuit — do not share with high-inrush HVAC or motor loads. A nuisance fuse trip on the input side drops all eight outputs and the battery charger simultaneously.

The T2MK5F8 is best positioned for mid-size commercial tenant buildouts — a 4–8 door office floor or a single-level retail or healthcare suite where all access hardware is within reasonable home-run distance of a single IDF closet. It's the clean, code-compliant choice when the spec calls for UL294 power and you want the enclosure, supply, and battery resolved in one procurement line.
