Altronix EFLOW104NXV 24VDC 10A Fire Alarm Disconnect Power Supply/Charger

Overview

The Altronix EFLOW104NXV is a single-output 24VDC power supply and battery charger built for international and commercial security installations where 220VAC is the standard mains voltage. It delivers a regulated 24VDC at up to 10A — enough headroom to drive access control panels, door hardware, or camera power distribution — while integrating fire alarm disconnect, battery backup management, and LinQ2 network reporting in a single wall-mount enclosure. For integrators working on commercial sites in 50/60Hz regions or U.S. facilities with 220VAC infrastructure, the Altronix surveillance power line offers a mature platform that eliminates the need for separate charger modules or external supervision relays.

Key Features

• 220VAC Input (198–256VAC Working Range): The EFLOW104NXV accepts a wide input voltage window — 198VAC to 256VAC — which absorbs common mains fluctuations without nuisance shutdowns. On sites with marginal utility supply or long wire runs from the panel, that 58V tolerance window is the difference between a stable installation and constant service calls.
• 24VDC @ 10A Output: Ten amps at 24VDC gives you meaningful capacity for multi-door access control runs, electric strikes, or aggregated camera power nodes. Most single-door controllers and their associated hardware draw well under 3A; this unit can serve three or four controlled points while leaving margin for inrush on lock release.
• 1A Unswitched Auxiliary Output: The auxiliary output remains live regardless of the main DC bus state, which is useful for powering a supervision relay, a reader held in bypass mode, or low-draw ancillary loads that shouldn't drop during a controlled shutdown event.
• Built-In Battery Charger — 1.54A Max: The onboard charger supports sealed lead-acid and gel-type batteries at up to 1.54A, with automatic switchover to standby the instant AC fails — no interruption, no momentary dropout. The enclosure accommodates two 12VDC/12AH batteries (sold separately), so you can build your runtime buffer inside the same cabinet rather than adding an external battery shelf.
• Fire Alarm Disconnect (FAI) — Supervised, Latching or Non-Latching: The supervised FAI circuit responds to a normally open or normally closed trigger and includes a 10K EOL resistor, making it compatible with standard fire alarm panel supervision loops. The notification trigger is selectable for 30 seconds (factory default) or 2 hours — useful when you need to suppress nuisance trips during scheduled maintenance windows. This is why the EFLOW104NXV belongs in any commercial power supply shortlist for fire-integrated security systems.
• AC Fail and Battery Supervision (Form C Contacts): Discrete form C contacts for both AC fail and battery fail/presence give the upstream panel or PSIM two independent dry-contact signals to monitor. You're not dependent on proprietary protocol support — standard hardwire supervision into whatever panel you're using.
• Low Power Shutdown — Deep Discharge Protection: If battery voltage drops below 70–75% of nominal, the unit shuts down the DC output terminals to prevent deep discharge damage. Sealed lead-acid batteries that are deep-cycled repeatedly fail early; this protection extends standby battery service life meaningfully on sites with frequent or extended power interruptions.
• Overvoltage and Short Circuit Protection: Both output protection modes are onboard, so a field wiring fault or a failed load doesn't cascade into supply damage. On large access control installations with dozens of field devices, this matters — a short on one home-run shouldn't take out the entire power node.
• LinQ2 Ready: The EFLOW104NXV is designed for the optional Altronix LinQ2 network communication module, which adds remote monitoring, diagnostics, and reporting of power supply status over IP. For enterprise deployments where a technician rolling a truck to check a power supply is not acceptable, LinQ2 integration means you get visibility into AC fail, battery state, and output current from your NOC.
• NDAA, TAA, BAA, and CE Compliant: The EFLOW104NXV carries NDAA Section 889 compliance, TAA compliance for GSA schedule use, BAA compliance for domestic content requirements, and CE marking for international deployments — a combination that qualifies it for federal, municipal, and international commercial projects without procurement exceptions.

Integration and Compatibility

The EFLOW104NXV integrates directly into access control systems requiring 24VDC power with fire alarm interlock — common in commercial buildings where life-safety codes require door hardware to release or lock on fire alarm. The supervised FAI with EOL resistor connects to standard NAC or auxiliary supervised circuits. LinQ2 module compatibility (accessory, sold separately) adds IP-based power monitoring for larger deployments managed through a PSIM or BMS platform. The wall-mount BC400 enclosure includes 1.125
