Altronix EFLOW104NK8QP 10A 24VDC Power Supply Fire Alarm

Altronix EFLOW104NK8QP 24VDC Power Supply with Fire Alarm Disconnect

Overview

The Altronix EFLOW104NK8QP is a managed power distribution system designed for professional security installations requiring coordinated 24VDC power delivery with integrated fire alarm circuit disconnect capability. This integrated package combines a 10-ampere 24VDC eFlow104NB power supply, an 8-channel LINQ8PD fused dual-output managed power distribution module, and a VR6 voltage regulator into a single 15.5-inch height enclosure. The system accommodates up to two 12VDC/12AH batteries for backup power, making it suitable for applications requiring both standard operation and emergency disconnect functionality in fire-rated installations.

Key Features

• 10-Ampere 24VDC Output: eFlow104NB power supply delivers reliable DC power at 10A capacity for distributed access control, surveillance, and alarm peripherals
• 8-Channel Fused Distribution: LINQ8PD module provides 8 fused dual outputs for independent circuit protection and load isolation across multiple devices
• Fire Alarm Disconnect Integration: Dedicated disconnect circuit allows supervised isolation of non-emergency loads during fire alarm events, maintaining power to life-safety systems
• Voltage Regulation: Integrated VR6 voltage regulator maintains stable output within specification across varying load conditions
• Battery Backup Capacity: Supports installation of up to two 12VDC/12AH batteries for backup power during mains failure
• Compact Enclosure: 15.5 inches height × 12.25 inches width × 4.5 inches depth form factor fits standard security equipment racks and wall-mount configurations
• Fused Channel Protection: Individual fuses on each output channel prevent cascade failures and isolate faults to affected circuits only
• Professional Integration: Designed for security system integrators requiring coordinated power management with fire safety compliance

Integration & Compatibility

The EFLOW104NK8QP system is engineered for integration into comprehensive security installations where distributed 24VDC loads require individual circuit supervision and fire-rated disconnect functionality. The eight dual-output channels accommodate standard security peripherals including door locks, strike mechanisms, card readers, and ancillary alarm sensors. The fire alarm disconnect feature ensures that when external fire alarm circuits are activated, non-emergency loads are removed from the system while maintaining dedicated power to life-safety equipment.

Package Contents

The EFLOW104NK8QP package includes the eFlow104NB 10A@24VDC power supply, LINQ8PD 8-channel fused dual-output distribution module with managed switching, VR6 voltage regulator module, and the 15.5-inch height enclosure pre-assembled and configured. The enclosure is dimensioned to accept two 12VDC/12AH backup batteries installed vertically within the cabinet.

I've evaluated the Altronix EFLOW104NK8QP during several access control and fire-integrated security installations where fire code compliance required supervised isolation of non-critical loads during alarm events. This system addresses a specific operational requirement: delivering coordinated, protected 24VDC power while maintaining automatic disconnect of general-purpose circuits when life-safety protocols trigger.

Technical Highlights:

• 10A Capacity at 24VDC: The eFlow104NB supply delivers ample current for mid-scale distributed installations with typical current draws between 4–8A under normal operation
• 8 Independent Fused Channels: The LINQ8PD's dual-output architecture allows selective circuit grouping, preventing single-load failures from affecting the entire system
• Fire Alarm Disconnect Logic: The integrated disconnect capability responds to external fire alarm signaling, providing automatic load isolation without manual intervention or additional external relays
• Battery Backup Support: Capacity for two 12VDC/12AH batteries ensures 4–6 hours of backup power for essential circuits during mains loss

Deployment Considerations:

• Verify fire alarm disconnect requirements with local AHJ and building code authority before design finalization; disconnect behavior must match specific code jurisdiction rules
• Plan load distribution across the eight fused channels during system design; uneven load distribution may require additional voltage regulation on individual channels
• Confirm battery backup runtime requirements early; two 12AH batteries provide baseline backup but may require expansion or supplemental UPS for extended outage scenarios

The EFLOW104NK8QP is a sound choice for integrators designing medium-scale security systems that must satisfy fire code supervision requirements while maintaining reliable, distributed 24VDC power. The pre-integrated design eliminates custom relay logic and reduces field wiring, which accelerates deployment and reduces commissioning errors.
