Altronix T2AXK3F8ADQ 8-Door Access Control Power Integration Kit
The Altronix T2AXK3F8ADQ is a factory-assembled, eight-door access control power kit built specifically for Axis Communications controller deployments. It bundles a Trove2AX2 enclosure with TAX2 backplane, eFlow6NB power supply/charger, VR6 voltage regulator, LINQ8ACMCB networked access power controller, and PDS8CB dual-input power distribution module — everything needed to power up to eight doors from a single 21.5"W x 27.25"H x 6.5"D enclosure. If you're integrating Altronix and Axis access control products, this kit eliminates the guesswork of component selection and dramatically reduces field wiring time.
Key Features
- 24VDC @ 6A Continuous Output: The eFlow6NB delivers regulated, filtered 24VDC at 6A continuous — enough headroom to drive eight door controllers plus auxiliary loads without voltage sag under surge conditions. A 1A unswitched auxiliary output handles supplemental devices.
- Integrated 12VDC Voltage Regulator (VR6): The onboard VR6 steps the 24V bus down to 12VDC at 6A continuous with surge suppression built in. Dual-voltage output from a single supply means you can mix 12V and 24V readers, locks, and peripherals on the same enclosure without a second power source.
- Networked Power Control via LINQ8ACMCB: Eight PTC-protected outputs are individually software-programmable — fail-safe, fail-secure, or auxiliary mode per output. High/low voltage and current monitoring per port means you'll catch a failing lock or shorted wire before it takes down a door. Outputs can be grouped to trigger from a single input event.
- Dual-Input PDS8CB Distribution Module: Each of the eight distribution outputs is individually selectable to follow 24V or 12V input, and any output can be switched off for servicing without cutting power to other doors. Per-output LEDs (green = 12V, red = 24V) give technicians instant visual status at the panel.
- Battery Backup with Deep-Discharge Protection: The eFlow6NB charges 12VDC/12AH sealed lead acid or gel batteries (up to four within the enclosure; larger 40AH/65AH banks require a separate enclosure). AC loss triggers instantaneous failover. The supply shuts down DC outputs before battery voltage drops below 70–75% of nominal — preventing deep discharge that kills lead acid batteries.
- AC and Battery Supervision: Form C dry contacts report both AC failure and battery fault conditions — wire directly to your FACP or head-end panel for monitored power status without additional supervision modules.
- 120VAC / 60Hz Input, 5A/250V Fused: Standard US single-phase input with 3.5A draw at full load. The 5A input fuse protects upstream wiring. CE compliance confirms the design meets European safety standards as well.
- Trove2 Enclosure with TAX2 Backplane: The Trove system pre-positions boards and manages wiring channels, reducing layout errors and cutting installation time. The TAX2 backplane is purpose-built for the Axis A1810-B controller — up to one A1810-B fits in this enclosure for true single-box eight-door deployments.
Integration and Compatibility
The T2AXK3F8ADQ is designed around the Axis A1810-B network door controller. The TAX2 backplane aligns Altronix power and the Axis controller on a common mounting surface, reducing point-to-point wiring to structured, labeled connection blocks. For deployments running access control systems with Axis hardware, this kit removes integration ambiguity between power and controller. The LINQ8ACMCB accepts 5VDC–24VDC wet inputs (with 10k resistor) as well as NO, NC, and open-collector sink triggers — compatible with a wide range of request-to-exit and door position switch types. Review the Altronix Altronix power and access catalog for compatible enclosure expanders and battery cabinets if your site needs more than 12AH runtime. Pair with a PoE switch for the Axis controller's network uplink — the controller itself is not powered through this kit's DC outputs.
Frequently Asked Questions
Q: How many doors can the T2AXK3F8ADQ support in a single enclosure?
A: The kit supports up to eight doors in a single Trove2AX2 enclosure when paired with one Axis A1810-B controller. The LINQ8ACMCB and PDS8CB each provide eight individually controlled, PTC-protected outputs.
Q: What battery types and capacities are supported?
A: The eFlow6NB charges sealed lead acid or gel type 12VDC batteries. Up to four 12AH batteries fit within the enclosure. Larger 40AH or 65AH batteries require a separate Altronix battery enclosure.
Q: Can individual door outputs be shut off for servicing without cutting power to other doors?
A: Yes. Both the LINQ8ACMCB and PDS8CB allow individual outputs to be set to OFF independently, so you can service one door circuit without disrupting the remaining seven.
Q: What input voltage does the T2AXK3F8ADQ require?
A: The kit requires 120VAC, 60Hz at 3.5A. It is intended for standard US single-phase circuits and includes a 5A/250V input fuse.
Q: Does the kit provide supervision for AC and battery failure?
A: Yes. The eFlow6NB includes Form C dry contacts for both AC failure and battery fault supervision, suitable for connection to a FACP or monitoring panel.
Q: What are the operating temperature limits?
A: The T2AXK3F8ADQ is rated for operation from 0°C to 49°C (32°F to 120°F), with storage rated from -20°C to 70°C. Relative humidity tolerance is 85% ±5%.
The T2AXK3F8ADQ is one of the cleaner eight-door power solutions I've put hands on. The LINQ8ACMCB's per-output current and voltage monitoring is the feature that separates this from a basic distribution panel — when a lock solenoid starts drawing high, you know before the door fails, not after a service call.
Technical Highlights:
- Dual-Voltage Architecture: 24VDC at 6A from the eFlow6NB feeding the LINQ8ACMCB, with the VR6 stepping down to 12VDC at 6A simultaneously — both rails are PTC-protected at 9A input and 2.5A per output, so a shorted lock won't cascade.
- Networked Output Control: Eight programmable outputs on the LINQ8ACMCB support fail-safe, fail-secure, or auxiliary modes per port, with timer events and multi-input triggering — this is access power management, not just distribution.
- Battery Failover: Instantaneous AC-loss failover with deep-discharge protection shutting down at 70–75% of 24V nominal protects your battery investment and maintains door uptime through power interruptions.
Deployment Considerations:
- The Trove2AX2 enclosure accommodates exactly one Axis A1810-B controller — verify your door count hits eight or plan a second enclosure before spec'ing this kit at larger sites.
- Batteries are sold separately; budget for four 12AH units inside the enclosure, or a dedicated Altronix battery cabinet if your hold-time requirement exceeds what four 12AH cells provide at 6A draw.
This kit is the right call for commercial office or healthcare buildouts running Axis A1810-B with a mix of 12V and 24V electric strikes — the dual-rail architecture and per-door software control eliminate the relay boards and secondary supplies that inflate labor costs on those projects.
