Siemens PS-35 Power Supply for System 3
The Siemens PS-35 is a power supply module for the legacy Siemens System 3 fire alarm platform. It delivers regulated DC power to System 3 panel components. As a result, the panel can run reliably under both normal and alarm conditions.
The PS-35 carries Siemens catalog number 500-884950. Specifically, it is a genuine Siemens replacement component for System 3 installations. Furthermore, OEM-quality power supplies matter on legacy platforms because the platform is no longer supported by new-build alternatives.
How the Siemens PS-35 Fits the System 3 Panel
First, the PS-35 supplies regulated DC to the panel’s electronics and field devices. Then, on AC loss, the BC-35 battery charger and transfer switch hands off to battery backup. Therefore, the PS-35 and BC-35 together form the primary power subsystem for Siemens System 3 panels. In addition, this pairing preserves the original Siemens power architecture for the platform.
Key Features
- Siemens catalog number 500-884950
- Regulated DC power for the Siemens System 3 platform
- Designed to pair with the BC-35 battery charger / transfer switch
- Genuine Siemens replacement component for legacy System 3 installations
- For facilities still operating original Siemens System 3 fire alarm panels
Important Compatibility Notes
System 3 is a legacy Siemens platform. Therefore, this PS-35 is intended for like-for-like replacement in an existing System 3 panel. However, it is not a drop-in for FireFinder XLS, Cerberus PRO, or other current Siemens platforms — those use different power architectures. Our team can help confirm whether your panel is actually System 3 before you order.
