# F&G Control Systems #system-component #control-system #safety Fire and Gas (F&G) Control Systems are integrated safety systems that monitor, detect, and respond to fire and gas hazards in industrial facilities. ## Components - **Detectors**: Fire and gas sensors - **Control Panels**: Central processing units - **Alarm Devices**: Visual and audible alarms - **Outputs**: Emergency shutdown, fire suppression activation - **Communication**: Integration with other systems ## Key Features ### SIL Certification - Should be SIL 2 certified minimum - Ensures reliability and safety - Compliance with IEC 61508/61511 - Critical for worker and asset protection ### Communication Capabilities - Multiple protocols: Modbus, Profibus, Ethernet, HART - Integration with ESD systems - Connection to fire suppression systems - Interoperability with automation systems ### Detector Integration - Compatible with wide variety of detectors - Fire detectors (smoke, heat, flame) - Gas detectors (point, open path) - Alarm devices ## Architecture - Centralized or distributed - Redundant systems for critical applications - Networked detectors - Remote monitoring capabilities ## Functions - Continuous monitoring - Alarm generation and annunciation - Emergency response activation - Data logging and reporting - Integration with safety systems ## Standards Compliance - IEC 61508: Functional safety - IEC 61511: Process industry safety - NFPA standards - Local regulations ## Related Concepts - [[Safety Integrity Level - SIL]] - [[IEC 61508]] - [[IEC 61511]]
