Altronix EFLOW6NXV 12/24VDC 6A Fire Alarm Power Supply with Enclosure
Overview
The Altronix EFLOW6NXV is a supervised, dual-voltage power supply engineered for fire alarm and access control applications where 220VAC mains power is the local standard. Delivering up to 6A of regulated DC output at either 12VDC or 24VDC, this unit ships pre-installed in an XL enclosure sized to house a battery backup alongside the supply itself — making it a self-contained power station rather than a bare board that still needs a cabinet. If you're commissioning a fire alarm panel in a facility running 220VAC distribution, the EFLOW6NXV is purpose-built for that environment.
Altronix has long focused on power distribution for the commercial security and life safety market. Browse the full Altronix power supply catalog for the broader EFLOW family and related distribution modules.
Key Features
- 220VAC Input with Wide Range Tolerance (198–256VAC): The EFLOW6NXV accepts input from 198VAC to 256VAC at 50/60Hz — that ±12% swing around nominal covers the real-world voltage sag common in older commercial buildings and international installations without tripping the supply offline. You won't need a separate line conditioner for typical facility fluctuations.
- 6A Output at 12VDC or 24VDC: Six amps of continuous regulated output is enough headroom to power a mid-size fire alarm power supply zone or a distributed access control head-end with room for expansion. Selecting 12VDC or 24VDC at commissioning lets you match the panel's native bus voltage rather than adding a conversion stage.
- 1A Auxiliary Output: The onboard 1A auxiliary output is sized for ancillary devices — notification appliances, auxiliary relays, or supplementary sensors — fed separately from the main 6A rail. Isolating these loads keeps a misbehaving peripheral from dragging down your primary panel power.
- Integrated SLA/Gel Battery Charger: The built-in charger supports both sealed lead acid and gel-type batteries, so you're not locked into a single battery chemistry. Standby battery backup is a code requirement on virtually every supervised fire alarm installation; having the charger on-board rather than as a plug-in module reduces wiring complexity and potential failure points.
- XL Enclosure Included: At 4.50 × 12.25 × 15.50 in, the XL steel enclosure provides genuine interior volume for a battery alongside the supply board. That's the difference between a product that ships ready to mount with a battery inside and one that requires a separate cabinet procurement step — relevant when you're scheduling a one-day rough-in and can't wait on a second delivery.
- FAI (Fire Alarm Interface) Design: The FAI designation signals that this supply is designed to interface directly with fire alarm control panels — supervision inputs, trouble outputs, and current-limited outputs that meet the expectations of listed fire alarm systems. This is not a generic CCTV or access power supply repurposed for life safety; the feature set is built around fire alarm panel integration from the start.
Integration & Compatibility
The EFLOW6NXV is designed for deployment alongside fire alarm control panels requiring a supervised, listed power supply with battery backup. The dual-voltage output (12VDC or 24VDC selectable) covers both common panel bus voltages. The FAI interface is suited for integration with conventional and addressable panel architectures where a separate, supervised power supply is required by the panel manufacturer or local AHJ. Battery compatibility spans sealed lead acid and gel-type chemistries — confirm battery AH rating and enclosure fit before ordering batteries separately, as the XL enclosure dimensions (15.50 in height) determine maximum battery size. For installations requiring multi-channel distribution from a single supply, pair this unit with an Altronix power distribution module appropriate to your output voltage.

Frequently Asked Questions
Q: What input voltage does the EFLOW6NXV require?
A: The EFLOW6NXV requires 220VAC input and accepts a range of 198VAC to 256VAC at 50/60Hz. It is not designed for standard 120VAC North American mains — verify your facility's power distribution before ordering.
Q: Can the EFLOW6NXV output both 12VDC and 24VDC simultaneously?
A: No. The output voltage is selectable at 12VDC or 24VDC — the unit operates at one voltage at a time. Select the voltage that matches your fire alarm panel's power input specification before installation.
Q: What type of batteries does the EFLOW6NXV support?
A: The integrated charger supports sealed lead acid (SLA) and gel-type batteries. Flooded or lithium chemistries are not listed as compatible — use only SLA or gel batteries to maintain proper charge regulation and avoid overcharging damage.
Q: Does the EFLOW6NXV include the enclosure?
A: Yes. The EFLOW6NXV ships with the XL steel enclosure measuring 4.50 × 12.25 × 15.50 in. The enclosure is sized to accommodate the supply board and a standby battery — no separate cabinet is needed.
Q: What is the auxiliary output rating on the EFLOW6NXV?
A: The auxiliary output is rated at 1A. It is intended for ancillary loads such as notification appliances or auxiliary relays, isolated from the main 6A output rail.
Q: Is the EFLOW6NXV suitable for 120VAC installations in the United States?
A: No. The EFLOW6NXV is rated for 220VAC input only. For 120VAC North American installations, Altronix offers other EFLOW variants designed for that input voltage. Confirm your local mains voltage before specifying this model.
The EFLOW6NXV is the model I specify when the job site is running 220VAC distribution and the panel integrator needs a listed, supervised supply that arrives with its enclosure already sorted. The 198–256VAC input tolerance is the spec I lean on most — on older commercial and industrial sites, you can see sustained low-voltage conditions that would take a narrower-tolerance supply offline during a fire event, which is exactly the wrong time for a power fault.
Technical Highlights:
- 6A Main Output: Six amps at 12VDC or 24VDC covers most mid-size fire alarm zone power budgets with margin for panel expansion — size your battery AH to match your required standby duration against this draw.
- 1A Auxiliary Rail: Keeping ancillary notification loads on the separate 1A output prevents a shorted sounder from pulling down panel power — a wiring discipline that's easy to enforce when the supply separates the rails for you.
- Integrated SLA/Gel Charger in XL Enclosure: The XL cabinet (15.50 in tall) gives you room to fit a meaningful standby battery inside the same enclosure — eliminating the external battery cabinet that often becomes a compliance question during AHJ inspection.
Deployment Considerations:
- Confirm your facility mains is 220VAC before ordering — this supply has no 120VAC tap and cannot be field-converted. The EFLOW6NXV is the wrong choice for standard North American 120VAC panel rooms without a step-up transformer in the circuit.
- Output voltage is set at commissioning (12VDC or 24VDC) — it does not auto-sense or switch dynamically. Mismatching the output to the panel bus voltage will damage connected equipment, so double-check the panel spec sheet before wiring.
This unit is well-suited to international facility deployments — manufacturing plants, warehouses, or commercial buildings in 220VAC regions — where the AHJ requires a supervised, battery-backed fire alarm power supply with an on-board charger and a code-ready enclosure, all in a single orderable SKU.
