Siemens XTRI-S Addressable Short Circuit Isolator

The Siemens XTRI-S is a compact, addressable short circuit isolator module designed for use with Siemens Cerberus PRO and Desigo Fire systems. This device is essential for maintaining system integrity by automatically isolating short circuits on the Signaling Line Circuit (SLC) loop, preventing a fault from taking down the entire system.

Engineered for reliable fire protection, the XTRI-S ensures continuous communication and fault isolation, making it a critical component for robust commercial fire alarm systems.
