The Siemens MS-501 is a modular system component (module/card) used within Siemens Cerberus PRO and FireFinder XLS intelligent fire alarm systems, with backward compatibility into MXL legacy infrastructure. It integrates into the modular system architecture as a field-replaceable component, preserving compatibility with the installed head-end.

Compatibility

• Component of UL 864 listed Siemens fire alarm systems
• Cerberus PRO and FireFinder XLS platforms with MXL legacy backward compatibility
• Installed and configured per Siemens documentation
• Verify revision and panel build before replacement

Key features

• Field-replaceable system component for modular architecture
• Integrates with the installed control and signaling infrastructure
• Supports backward compatibility into MXL legacy installations
• Serviceable without re-engineering the head-end
• Maintains supervision and reporting of the host system
• Matched to the panel build and firmware revision

Interface, control, and zone modules connect conventional or third-party field wiring, outputs, and supervisory circuits into the addressable system, extending control and monitoring without re-engineering the head-end. Confirm module class against the panel build.

Verify panel/device family compatibility before ordering.
