Reliability-operational analysis of fixed gas fire extinguishing equipment integrated with fire signalling systems

Fire protection of server rooms and data processing centres, located in public buildings, uses fire extinguishing equipment known as fixed gas fire extinguishing devices (SUG-G). The extinguishing medium (gas in tanks) should be stored at a location indicated in the fire scenario and in the technical contractor project for SUG-G. SUG-G is intended to extinguish a fire in its initial stages and to prevent fire spreading. The fire signalling central station (CSP) receives a fire signal from a group of sensors located in the protected premise and notifies the Fire Brigade (PS), whilst the fire extinguishing control room automatically starts the gas extinguishing process. Such use of a signalling and extinguishing system results in a redundant system. This improves reliability of the fire signalling system (SSP), which is responsible for safety inside the building.
