- Abstract:
- This paper analyzed the definition of preaction system, the sprinkler opening time test of Tianjin Fire Research Institute of the Ministry of Public Security, and the selection of fire alarm system based on Code for Design of Sprinkler Systems (GB 50084-2017) and Manual for Design of Sprinkler Systems, and verified the feasibility of preaction automatic sprinkler system for fire control and extinguishing in high and large space buildings. A single chain preaction sprinkler system could be used on the premise that image type flame detectors were equipped and a reasonable water filling time was set (the recommended value is less than 90 s) in civil buildings and factories with large spaces according to table 5.0.2 specified in GB 50084-2017.
