Siemens FDM225 RG Manual Call Point with Glass Plate

The Siemens FDM225 RG Manual Call Point with Glass Plate is an addressable manual call point equipped with a frangible glass plate element for immediate emergency fire alarm initiation. Developed by Siemens for Sinteso and Cerberus PRO fire detection systems using FDnet/C-NET addressable communication, the unit features a durable red plastic enclosure designed for standard indoor surface or flush installations. It utilizes a breakable glass plate operating element for direct, unmistakable emergency triggering, an integrated line separator (isolator) to protect loop communication against short-circuit faults, electronic soft-addressing, an internal red status LED for polling and alarm confirmation, screw terminal connections, and seamless integration with Siemens addressable control panels.
