(7) Automatic water spraying fire extinguishing system is set up in this project. The setting place of fire danger rating for the dangerous level (Level 1), automatic sprinkler system design for wet type automatic water spraying fire extinguishing system, system uses a central water spray, head selects ZST-20 series of standards rapid response of glass ball sprinkler.
(8) The engineering anti smoke exhaust design to use the combination of natural and mechanical smoke exhaust, each layer of smoke preventing zoning in the span of fireproof subarea based on partition, underground layer 2, the first floor, two thousand three hundred forty-five each of the three fire partition. In the basement of the fire room, a pressurized air supply system is set up, and the fan is arranged on the ground.
(9) The fire automatic alarm system of the project is two level, and the centralized alarm system is set up. In the underground equipment room, water pump room and other relative humidity is higher in the choice of intelligent smoke detector, the first floor and above the floor of the room and the public places, choose intelligent smoke detector. Each fire partition set up a manual alarm button arranged at both ends of the corridor, the central corridor, stairs and other regions, installed on the wall, away from the bottom (floor) surface height of 1.3 ~ 1.4 m, and clearly marked.
