G. The project with the fire hydrant system is a low-pressure pump and tank water supply system. The hotel part of its water for the fire hydrant 33.6L / s, fire water volume of 18m3, arranged a ground water pump adapter, and set a fire hydrant on the flat roof of the roof.
H. The project fire danger rating for Class I in danger. Wet automatic sprinkler system, the system of water pipes in a ring shape, with the sides of the center uses water pipes water supply arrangement. Independent of wet alarm valve, and equipped with alarm control device. Automatic sprinkler system sprinkler strength 6L / minm2, active area of 160m2, arranged nozzle spacing 3.6m. The most unfavorable point nozzle working pressure of P0 = 0.05MPa. Hotel sprinkler system Total system flow 30.78L / s.
I. place this project as a whole Extinguisher A fire danger rating as a serious risk level, each matching a fire extinguisher set point ammonium phosphate dry powder portable fire extinguisher.
J. This project uses natural combination of smoke and smoke way. Part of a hotel room can be opened outside the window, naturally smoke, equipped with mechanical exhaust stairwell.
K. automatic fire alarm system to protect this project grade level, the use of the fire alarm system control center form. System with the fire control room, fire emergency radio, manual fire alarm buttons. Smart smoke detector, which are used in the form of point-type fire detectors arranged.
