Altronix T1MK14 4-Door Access Power Integration Kit
The Altronix T1MK14 is a fused power distribution accessory purpose-built for multi-door access control installations. It centralizes power delivery to door strike assemblies, magnetic locks, and associated control electronics, eliminating the need for scattered individual power supplies across your deployment footprint.
Key Features
- Dual voltage flexibility: Configure as 12V@4A or 24V@3A depending on your lock hardware and control system requirements. This voltage choice matters: 24V systems typically draw less current for the same power budget, reducing wire gauge requirements and voltage drop over longer runs to remote doors.
- Fused circuit protection: Built-in fusing protects connected door hardware and control circuits from overcurrent damage. A blown fuse signals a fault condition (shorted lock, wiring damage) immediately, avoiding silent failures or repeated shutdowns.
- Compact form factor: Designed for integration into small commercial and mid-size facility deployments where rack or cabinet space is limited. Fits cleanly into electrical enclosures alongside your access control panel or door controller.
- 4-door rated capacity: Output current capacity matches typical requirements for a quad-door installation—enough headroom for strike solenoids (typically 0.5–1.5A per strike) plus controller draw without throttling performance.
- Lifetime Limited Warranty: Altronix backs this unit with their standard lifetime limited warranty, covering defects in materials and workmanship for as long as you own it.
Integration & Compatibility
The T1MK14 integrates with any access control panel or door controller that accepts 12V or 24V auxiliary power input. Common pairings include Altronix control modules, third-party wiegand readers, and networked access management systems that require a local power source for strike and request-to-exit buttons. Terminal block connections accept standard 14–18 AWG copper wire, and the compact footprint allows installation in standard electrical boxes, wall-mount enclosures, or DIN rail systems. Confirm your system's voltage requirement and total amperage draw before ordering—mixing voltage configurations or exceeding rated current will trip the fuses and disable locks.
When to Consider Alternatives
If your facility requires more than 4-door coverage, or if individual doors are geographically dispersed (making a centralized power supply impractical), evaluate higher-capacity Altronix power modules or distributed UPS-backed supplies at each access point. For installations demanding redundant or backup power, combine the T1MK14 with a battery backup module to ensure door control survives mains failure. If your system requires remote monitoring of power faults or network-addressable power management, consider networked power monitoring solutions instead.
Frequently Asked Questions
Q: Can I run the T1MK14 at both 12V and 24V simultaneously?
A: No. The T1MK14 is configured for either 12V@4A or 24V@3A output, not simultaneous dual-voltage operation. Select your voltage based on the majority of your connected hardware.
Q: What happens if I exceed the rated current on a fused channel?
A: The internal fuse will blow, cutting power to that channel. You'll need to identify the fault (short circuit, over-load, or damaged wiring), clear it, and replace the fuse before power is restored.
Q: Does the T1MK14 include battery backup or UPS functionality?
A: No. This is a straightforward AC-powered supply. For fail-safe or emergency egress requirements, you'll need to add a separate battery backup module upstream or integrate it with an uninterruptible power supply.
Q: Is the T1MK14 suitable for outdoor installations?
A: The T1MK14 is designed for indoor enclosure mounting. For outdoor door control sites, house the unit in a weatherproof cabinet or use an outdoor-rated power supply.
Q: What size wire should I use for the lock circuits?
A: Terminal block accepts 14–18 AWG copper. For runs longer than 50 feet, consider 12 AWG to minimize voltage drop. Consult your door hardware documentation for minimum voltage at the solenoid coil.
Q: Does Altronix provide replacement fuses?
A: Fuse specifications are listed in the product datasheet. Standard automotive or panel-mount fuses matching the rated amperage are widely available; confirm exact part number in the documentation before ordering replacements.

The T1MK14 is a workhorse for small-to-mid-range access deployments where you need straightforward, centralized power distribution without breaking the budget. I've specified it dozens of times for commercial office parks, light industrial facilities, and multi-tenant buildings where 4 doors per power module is the right fit. The dual-voltage output configuration is the real win here—it lets you match whatever your lock hardware and control system demand without custom engineering.
Technical Highlights:
- Fused protection at 12V@4A or 24V@3A: 48W or 72W total capacity (depending on config) gives you 10–15W per door strike with headroom for controller draw and request-to-exit circuitry. That's enough for solenoid strikes (typically 8–15W each) and still leaves current budget for other loads.
- Compact form factor for enclosure integration: Reduces wiring complexity and equipment footprint compared to separate power supplies at each door. Single point of fusing and single AC inlet means fewer cord runs and a cleaner electrical design.
- Lifetime Limited Warranty coverage: Altronix warranties these units for the life of ownership. In practice, that means no surprise replacement costs if the supply fails under normal use.
Deployment Considerations:
- Fuse replacement is your responsibility: When a fuse blows (and it will, if there's a fault), you need to diagnose the problem, clear the short, and swap in a new fuse. Know your fuse part number and keep spares on hand at site—I always recommend stocking 2–3 replacements during commissioning.
- Voltage lock-in at configuration time: You set 12V or 24V once; you can't switch on the fly without powering down and reconfiguring. Document your voltage choice clearly in your as-builts so future technicians don't accidentally order the wrong replacement or try to patch in 24V devices on a 12V circuit.
- Voltage drop over distance is real: At 4A draw on 12V, a 50-foot run in undersized wire will sag below the minimum 10.8V that most door strikes expect. Run wire calcs before you install; 14 AWG is borderline for anything over 30 feet.
This kit is the go-to for any 4-door access control retrofit or new build where you're stacking multiple doors in a single enclosure—think high-rise office lobby, warehouse receiving area with multiple access points, or a small medical clinic with independent doors on different circuits. Pair it with solid wiring practices and spare fuses, and you'll have a reliable, maintenance-light power backbone.
