Altronix T1DMK34D TROVE1 Series Power Supply and Module Enclosure Kit
Overview
The Altronix T1DMK34D is a UL294-listed, wall-mount power supply enclosure kit purpose-built for integrated access control and surveillance installations that demand a clean, code-compliant power distribution chassis. At its core, this kit delivers 12VDC or 24VDC selectable output at 6A continuous — enough headroom to drive multiple access control devices, door hardware, and peripheral devices off a single, supervised source. The enclosure accommodates up to four DMP 734/734N expansion modules, making it a natural fit for DMP-based installations where you need panel and power in one raceable box rather than scattered wall-mount hardware.
For security integrators running Altronix power distribution products across commercial deployments, the T1DMK34D eliminates the guesswork of sizing enclosures and sourcing separate power supplies — the kit ships as a matched assembly rated and listed for the application.
Key Features
- Selectable 12VDC or 24VDC Output at 6A Continuous: The ability to switch output voltage at the supply — rather than at the load — simplifies installations where door strikes, mag-locks, or readers differ between 12V and 24V requirements. At 6A continuous, there is ample current for mixed hardware loads without derate concerns under typical access control head counts.
- Eight Individual Supervised Outputs: Eight discrete outputs mean you can assign, fuse, and monitor each load independently rather than daisy-chaining devices onto shared runs. On a multi-door deployment, this translates directly to fault isolation — a single shorted lock or reader doesn't pull the entire distribution circuit. Each output supports individual PTC protection, so an overload on one circuit doesn't take down adjacent doors.
- Dual 7AH/12VDC Battery Capacity: Two 7AH batteries provide standby reserve for UL294-compliant battery backup, keeping access control hardware alive through power interruptions. At typical access control load levels, this supports multi-hour standby runtimes — confirm your specific load budget against the 6A output rating when sizing hold-up time.
- AC Fail and Battery Supervision via Form C Contacts: Both AC loss and battery health are reported via Form C contacts, which gives your panel or monitoring system a dry-contact input it can act on — triggering alarms, logging events, or escalating to a central station. This is not a soft-alarm output; it's a physical contact change you can wire to any panel with a supervised zone input.
- UL294, cUL (CAN/ULC-S319-05), and CE Listings: UL294 listing means the unit has been third-party evaluated as an access control power supply — not just a generic power supply with a UL mark on the transformer. For AHJ inspections and insurance requirements on commercial access control systems, this is the listing that matters. The cUL listing extends compliance to Canadian installations under ULC-S319-05.
- Up to Four DMP 734/734N Module Capacity: The enclosure is mechanically and electrically configured for DMP 734 and 734N expansion modules — up to four units. For DMP panel integrators, this means the T1DMK34D functions as a self-contained expansion chassis, centralizing both power and module real estate in one inspectable enclosure rather than distributing modules across auxiliary hardware.
- Conduit Knockout Configuration: One 1-1/2-inch conduit and nine 1-inch/3/4-inch knockouts give installers flexibility for raceway entry from multiple directions without field-drilling the enclosure. On retrofit jobs where conduit routing is dictated by existing pathways, having nine smaller knockouts available versus a single fixed entry significantly reduces installation time.
- 0°C to 49°C Operating Range: The operating temperature envelope covers standard interior mechanical room and utility corridor environments. This is not a rated outdoor or unheated space enclosure — plan accordingly for installations in unconditioned areas that may approach or exceed 49°C in summer months.
Integration and Compatibility
The T1DMK34D is specifically designed to house DMP 734 and 734N expansion modules — up to four per enclosure. If your deployment uses DMP intrusion or access control panels and you need centralized expansion capacity co-located with a listed power source, this is the purpose-matched enclosure. The 18 x 14.5 x 4.62-inch interior dimensions and conduit knockout pattern should be confirmed against your local conduit routing plan before ordering. Input is 115VAC, 60Hz at 3.5A maximum draw, so a standard 20A branch circuit will support multiple units on the same circuit if your load calculations permit.
For installations requiring access control power supplies compliant with UL294, the T1DMK34D integrates into a broader Altronix TROVE series ecosystem alongside compatible enclosures and module kits. When planning the overall power architecture for a multi-door deployment, reference a access control planning guide to align battery standby requirements, output load per door, and supervision wiring to your panel's input capabilities.
Frequently Asked Questions
Q: What output voltages does the T1DMK34D support?
A: The T1DMK34D provides selectable 12VDC or 24VDC output at 6A continuous maximum. Voltage selection is made at the supply, allowing you to match the output to your specific door hardware requirements.
Q: How many DMP modules can the T1DMK34D enclosure accommodate?
A: The enclosure supports up to four DMP 734 or 734N expansion modules, making it a purpose-built chassis for DMP-based access control and intrusion installations that need co-located power and expansion capacity.
Q: What certifications does the T1DMK34D carry?
A: The T1DMK34D is UL294-listed for access control power supplies, cUL-listed under CAN/ULC-S319-05 for Canadian installations, and carries CE marking for European conformity.
Q: What battery backup capacity does the T1DMK34D include?
A: The kit supports two 7AH/12VDC batteries for UL294-compliant standby power. Actual hold-up time depends on connected load — calculate your total current draw against the 6A output rating to determine runtime.
Q: How are faults reported on the T1DMK34D?
A: AC fail and battery conditions are each reported via Form C dry contacts. These can be wired to any supervised zone input on a compatible panel or monitoring system for alarm reporting and event logging.
Q: What is the operating temperature range for the T1DMK34D?
A: The T1DMK34D is rated for 0°C to 49°C (32°F to 120°F) operating temperature. It is designed for conditioned interior environments and is not rated for outdoor or unheated spaces that may exceed this range.
The T1DMK34D is the kit I reach for on DMP-centric commercial access control jobs where the AHJ wants a UL294-listed power source in the same inspectable enclosure as the expansion modules — it eliminates the common field improvisation of mounting a generic supply next to an unlisted module rack. The 6A continuous output at selectable 12 or 24VDC handles a realistic multi-door load without running close to the thermal limit, and the dual 7AH battery provision satisfies standby requirements without a separate battery cabinet cluttering the telecom room.
Technical Highlights:
- Eight PTC-protected individual outputs: Fault isolation per circuit is the practical payoff here — on an eight-door deployment, a wiring fault at door six doesn't disable doors one through five. That's a runtime and liability argument you can make directly to the end user.
- Form C supervision contacts for AC and battery: Both fault types deliver a physical contact change, not a software flag. Wire these to your panel's supervised zones and the monitoring station picks up AC loss or a degraded battery without any additional relay hardware in the loop.
- UL294 and cUL (CAN/ULC-S319-05) listings: UL294 is the specific listing for access control power supplies — it covers the full product, not just a component on the board. This passes AHJ review on commercial projects in both US and Canadian jurisdictions without requiring a variance letter.
Deployment Considerations:
- Confirm conduit routing against the knockout pattern before rough-in — the nine 1-inch/3/4-inch knockouts give flexibility, but the single 1-1/2-inch knockout limits large-conduit entry to one path. Plan your home-run accordingly.
- The 49°C upper operating limit is the spec to watch in mechanical rooms with poor ventilation or in southern climate installs — a summer ambient of 45°C leaves almost no margin before you're outside the rated envelope. Verify HVAC conditions before mounting.
The T1DMK34D is the right specification for a DMP panel upgrade or new commercial build-out where the low-voltage contractor needs a single, UL294-listed assembly that consolidates power, module expansion, and battery backup into one wall-mount enclosure — and where the AHJ inspection plan depends on a listed product, not a field-assembled equivalent.
