SIEMENS S54430-C26-A1 Fire Alarm Power Supply & Battery Charger
Product Dimensions:
The Siemens S54430-C26-A1 (commonly known by its part number PSC-12M) is a high-capacity Main Power Supply and Battery Charger Module designed specifically for Siemens advanced fire alarm systems, including the Desigo CC, FireFinder XLS, and Cerberus PRO (XLS) series.
Product Detailed Description
The PSC-12M (S54430-C26-A1) serves as the primary power hub for a fire alarm control panel enclosure. It converts primary AC mains power into regulated DC power to operate the control panel, network modules, and connected system cards while simultaneously maintaining and charging standby batteries. It features built-in microprocessors that continuously monitor power quality, battery health, and ground fault conditions.
Technical Parameters

Product Advantages
- High Output Capacity: Delivers a robust 12-Amp filtered DC output, providing ample power for large-scale, multi-loop commercial fire alarm networks.
- Intelligent Battery Management: Uses microprocessor control to adjust charge rates dynamically based on battery condition and temperature, extending battery life and preventing overcharging.
- Comprehensive Diagnostics: Constantly monitors primary AC status, battery presence/voltage, earth ground faults, and internal fuse states, reporting diagnostic data directly to the main panel CPU.
- Universal Input Support: Supports both standard 120 V AC and 220/240 V AC inputs, making it versatile for domestic and international installation standards.
Important Considerations (Precautions)
- Battery Sizing: Ensure the standby batteries connected to the PSC-12M are within the supported 15 Ah to 100 Ah range; using under- or over-sized batteries can cause false trouble signals or improper charging.
- Power-Limited vs. Non-Power-Limited Wiring: Maintain strict physical separation (typically at least 0.25 inches or 6.35 mm) between high-voltage AC mains input and low-voltage power-limited field wiring inside the enclosure.
- AC Mains Isolation: Always turn off the dedicated primary AC breaker prior to connecting, disconnecting, or performing maintenance on the power supply module.
- Heat Dissipation: Ensure the control cabinet’s ventilation slots are unobstructed, as power supply modules generate noticeable heat during heavy charging cycles.
Product Applications
The PSC-12M is essential for life safety and fire protection infrastructure:
- Fire Alarm Control Panels: Serving as the core power engine in Siemens FireFinder XLS, Cerberus PRO Modular, and Desigo Fire Safety systems.
- High-Rise Commercial Buildings: Supplying clean, uninterrupted power to multi-node panels and emergency voice evacuation systems.
- Hospitals & Educational Campuses: Powering campus-wide, networked life safety nodes requiring large battery backup capacity.
- Industrial Facilities: Providing reliable system power in large manufacturing plants where power quality must remain stable during high ambient electrical noise.
