Whether you're upgrading legacy fire panels or deploying new installations, the FX808326 provides the stable voltage foundation your safety systems require.

With built-in protection circuits and wide operating temperature tolerance, this module eliminates common power-related failures that compromise alarm system integrity. Its 6.25-ampere maximum output handles demanding configurations including multiple detection loops, notification appliances, and auxiliary control circuits within a single compact footprint.

Core Capabilities & Technical Advantages

→ Precision Voltage Regulation: Maintains stable 24VDC output with minimal ripple (≤150mV peak-to-peak), preventing false alarms and ensuring consistent detector sensitivity across all connected zones.

→ High-Efficiency Power Conversion: Achieves ≥85% efficiency rating, reducing heat generation and operational costs while supporting environmentally conscious facility management goals.

→ Multi-Layer Circuit Protection: Integrated overvoltage, short-circuit, overload, and thermal shutdown safeguards protect both the module and downstream fire alarm components from electrical faults.

→ Wide Input Voltage Tolerance: Accepts 230VAC ±10% input (207-253V range), compensating for utility grid fluctuations common in industrial and remote locations without requiring external voltage regulators.

✓ Tool-Free DIN Rail Installation: Standard 35mm DIN-rail mounting enables rapid deployment and hot-swap replacement during maintenance windows without specialized tools or panel modifications.

✓ Extended Environmental Range: Operates reliably from -10°C to +55°C ambient temperature, suitable for unheated equipment rooms, outdoor enclosures, and harsh industrial environments.

Industry-Specific Application Scenarios

Commercial Office Complexes: Powers centralized FlexES fire alarm panels serving multi-floor buildings with distributed smoke detectors, manual pull stations, and audible/visual notification devices. Solves the challenge of maintaining code-compliant power backup for 24-hour occupancy facilities.

Manufacturing & Warehouse Operations: Supports fire detection systems in high-bay industrial spaces where ambient temperatures fluctuate and electrical noise from machinery can disrupt sensitive electronics. Delivers clean, regulated power that maintains detector accuracy despite harsh conditions.

Healthcare Facilities: Ensures continuous operation of life-safety systems in hospitals and clinics where power interruptions could delay emergency response. Meets strict healthcare electrical codes requiring supervised power supplies for fire alarm infrastructure.

Educational Institutions: Provides reliable power for campus-wide fire alarm networks spanning multiple buildings, supporting both legacy and modern detection technologies through consistent voltage delivery.

Retail & Hospitality: Enables 24/7 fire protection in shopping centers, hotels, and entertainment venues where public safety regulations mandate redundant power architectures and continuous system monitoring.

Technical Specifications & Selection Guide

Selection Criteria: Calculate total current draw of all connected devices (detectors, modules, notification appliances) and ensure the sum remains below 6.0A to maintain 20% safety margin. For systems requiring >120W continuous load, consider parallel redundant configuration or higher-capacity models. Verify input voltage matches local utility standards (230VAC for European/Asian installations).

Advanced Integration & System Expansion

The FX808326 integrates seamlessly into distributed fire alarm architectures, supporting both standalone panel configurations and networked multi-building systems. For enhanced reliability, pair with uninterruptible power supply (UPS) modules to maintain operation during utility outages. The module's low electromagnetic interference (EMI) profile ensures compatibility with sensitive communication equipment and networked control systems.

When designing redundant power schemes, this unit can be combined with automatic transfer switches or diode-isolated parallel configurations to achieve N+1 redundancy. Its compact form factor allows installation in space-constrained electrical cabinets alongside other fire alarm system components without requiring oversized enclosures.

Delivery Timeline & Service Commitment

Standard Lead Time: In-stock units ship within 2-3 business days via express courier services. Typical delivery to major commercial centers: 5-7 business days (domestic), 10-15 business days (international).

Custom Configuration: Special voltage variants or extended temperature range models available with 3-4 week lead time for orders of 10+ units.

Frequently Asked Questions

Can the FX808326 power non-Honeywell fire alarm panels?
Yes, this is a universal 24VDC regulated power supply suitable for any fire alarm control panel or industrial equipment requiring 24-volt DC power within the 150-watt capacity limit. Verify your panel's voltage and current specifications match before installation.

What happens if connected load exceeds 150 watts?
The integrated overload protection circuit will limit output current to prevent damage. The module will enter current-limiting mode, potentially causing voltage drop. For loads exceeding 120W continuous, we recommend upgrading to a higher-capacity model or implementing a dual-supply configuration.

Is battery backup integration supported?
While the FX808326 does not include internal battery charging circuits, it can be paired with external battery backup modules or UPS systems designed for 24VDC fire alarm applications. Consult your fire alarm panel documentation for approved battery backup solutions.

How do I calculate if this module meets my system requirements?
Sum the current draw of all devices: smoke detectors (typically 50-200μA standby, 30-50mA alarm), notification appliances (strobes: 60-195mA, horns: 15-30mA), and control modules (20-100mA each). Ensure total remains below 6000mA with 20% safety margin (4800mA maximum recommended continuous load).

What maintenance does this power supply require?
The FX808326 is a solid-state device requiring minimal maintenance. Recommended annual inspection includes: visual check for dust accumulation, verification of terminal connections, output voltage measurement (should read 24.0-24.5VDC), and thermal inspection using infrared camera to detect abnormal heating.

Can this module operate in outdoor environments?
The IP20 rating limits use to indoor protected environments. For outdoor installations, house the module in a weatherproof NEMA 4X or IP65-rated enclosure with adequate ventilation to prevent condensation and maintain operating temperature range.
