The Sigma Si range of status indicators provides comprehensive status information for Sigma XT/XT+ extinguishant release control systems. Each model features high-brightness LEDs to clearly display system conditions including Manual Only, Automatic and Manual, Hold Operated, Disabled, Imminent, and Released. Optional models include zonal fire indicators and a common fault indicator for enhanced monitoring.
For installations requiring local control of Automatic/Manual mode or manual extinguishant release, certain units are fitted with these controls. All models feature monitored inputs for remote connection of Automatic/Manual mode and Hold switches, ensuring seamless integration with the main control system. A large LED display provides a countdown timer showing the seconds remaining until extinguishant release.
