Siemens ST-50 Isolator Module

The Siemens ST-50 Isolator Module is an essential component designed to protect the integrity of the addressable Signaling Line Circuit (SLC) in a fire alarm system. This module automatically isolates sections of the circuit in the event of a short-circuit, preventing the fault from taking down the entire system.

Engineered for reliable fire safety, the ST-50 ensures system uptime and continuous monitoring, making it a critical device for commercial building fire protection.
