Altronix EFLOW104NX16 24VDC Power Supply/Charger
Overview
The Altronix EFLOW104NX16 is a 24VDC regulated power supply and charger designed for security system integration in institutional and commercial installations. This unit delivers 10A continuous output through 16 independently fused distribution circuits, providing redundant power paths to distributed security devices. The EFLOW104NX16 operates from standard 120VAC 60Hz mains input and includes integrated battery backup charging capability with battery presence supervision, making it suitable for applications requiring maintained power to critical access control, video surveillance, and intrusion detection infrastructure.
Key Features
- 16 Fused Outputs: Independently fused distribution channels allow circuit-level protection and isolation, reducing downtime from single-device faults.
- 24VDC @ 10A Rated Output: Sufficient capacity for mid-scale security installations with multiple downstream devices and sensors.
- 120VAC 60Hz Input Compatibility: Operates directly from standard North American mains power without transformer requirement.
- Battery Backup Charging: Integrated charger supports battery backup modules, enabling critical system operation during mains interruption.
- Battery Presence Supervision: Automatic monitoring confirms battery module connectivity and readiness without manual verification.
- Fire Alarm Disconnect: Hardwired disconnect protocol ensures safe de-energization during fire alarm activation, meeting life-safety code requirements.
- Auxiliary Output: Dedicated auxiliary terminal pair supports secondary load or signaling requirement independent of primary fused circuits.
- UL Listed: Certified for safety and performance in U.S. and Canadian installations.
- BC400 Enclosure: Compact steel cabinet design suits wall mounting in equipment rooms, telecommunications closets, and secure facilities.
- LinQ2 Ready: Firmware and interface support Altronix LinQ2 cloud management platform for remote status monitoring and diagnostics.
- FAI Compliant: Meets Fire Alarm Interface standards for integration with monitored fire alarm control panels.
Integration & Compatibility
The EFLOW104NX16 functions as a power distribution hub within larger security architectures. Its 16 fused outputs allow independent circuit assignment to access control readers, door locks, video encoders, IP intercoms, or motion sensors without shared load risks. The fire alarm disconnect interface provides automatic power removal on alarm activation, a requirement in many jurisdictions for life-safety compliance. Battery backup capability transforms this supply into a maintained-power system capable of sustaining critical devices during mains power loss. The LinQ2 integration allows remote monitoring of output status, battery health, and fault conditions from centralized management dashboards, reducing on-site troubleshooting overhead for multi-site operators.
Deployment Context
This supply class is typically deployed in educational institutions, corporate campuses, healthcare facilities, and government buildings where security infrastructure spans multiple zones and requires both granular control and redundancy. The 10A total capacity suits installations with 20–60 distributed devices, depending on individual device power demand. The EFLOW104NX16 works in parallel with backup power (UPS or battery modules) to ensure that critical pathways, door access, and surveillance recording remain operational during power events. Proper load balancing across the 16 circuits maximizes available capacity per circuit and minimizes nuisance fuse trips.
Ted PerryPerspective based on aggregated IP Security Depot and affiliated engineering team experience.
I have specified the Altronix EFLOW104NX16 on multiple campuses and municipal facilities where distributed access control and surveillance require resilient, supervised power architecture. The combination of 16 independent fused circuits and battery backup charging transforms a basic supply into a fault-tolerant power backbone. The EFLOW104NX16 has proven reliable in installations where a single power loss can trigger immediate lockdowns or loss of recorded evidence.
Technical Highlights:
- Fire Alarm Integration: Hardwired disconnect ensures safe, code-compliant de-energization during emergencies without relying on networked commands or battery depletion.
- Battery Presence Supervision: Eliminates the need for manual battery verification rounds; the supply alerts administrators to missing or depleted backup modules before an outage occurs.
- 16-Circuit Distribution: Each fused output can be assigned independently, reducing cascading failures and allowing phased upgrades without system-wide shutdown.
Deployment Considerations:
- Load balance across the 16 outputs to keep individual circuit current under 2A per circuit; this reduces fuse nuisance trips and extends device lifespan.
- Pair the EFLOW104NX16 with a battery module rated for at least 4–6 hours of autonomy if life-safety devices (door locks, emergency lighting) are connected.
- Verify that your fire alarm control panel supports FAI protocol before installation; some legacy systems require additional wiring modules.
- Use LinQ2 monitoring to track output voltage and battery charge cycles; this data aids predictive maintenance and identifies aging battery modules.
For integrators managing multi-site security deployments, the EFLOW104NX16 offers the right balance of capacity, resilience, and supervisory clarity. Plan for dedicated battery backup and ensure local team training on fire alarm disconnect procedures.
