Siemens FS-250 Signal System Equipment Enclosure Fire Alarm

The Siemens FS-250 Signal System Equipment Enclosure is a UL-listed, metal enclosure designed to house FS-250 fire alarm system modules and related accessories in commercial installations, providing a fixed mounting solution for field devices in a code-compliant housing. It is offered in two standard configurations—CAB2 Two-Row Enclosure and CAB3 Three-Row Enclosure—giving installers the choice of footprint and internal arrangement to fit the FS-250 components as specified by Siemens. Optional accessories such as the FS-SAU2 annunciator unit and the FS-RU2 serial relay unit are designed to mount inside the enclosure, enabling extended annunciation and signaling capabilities for FS-250 systems. Installation should be performed by qualified personnel according to Siemens FS-250 enclosure guidelines to ensure proper fit, wiring clearance, and compliance with fire-safety regulations.
