What Are Fire and Gas Safety Systems ?

Fire and gas safety systems continuously monitors for abnormal situations, such as a fire, or combustible or toxic gas release within the plant. They provide early warning and mitigation actions to prevent escalation of the incident and protect the process or environment.

A typical fire and gas safety system comprises detection, logic control, and alarm and mitigation functions. Logic solver is the central control unit of the overall fire and gas detection and control system. The controller receives alarm and status or analog signals from field monitoring devices required for fire and gas detection. The controller handles the required actions to initiate alarms and mitigate the hazard.

Normally, a fire and gas system combines fire and gas detectors, conventional and analog addressable fire panels, clean agent and inert gas fire suppression systems, and a SIL 3-certified fire and gas logic solver into a consistently designed and executed solution. An integrated system provides common tools, operating interface, and networking, resulting in a common platform with independent systems.

Gas Detectors are broadly divided into 2 types, flammable gas detectors and toxic gas detectors, and fire detectors are divided into 3 types, smoke detectors, heat detectors, and flame detectors.
