EASY INTRODUCTION TO FIRE FIGHTING SYSTEM IN A BUILDING

1.             .
   
       Fire fighting Sprinkler system is simple. Consisted of Pumps. Storage Tank, must have a reservoir. Sprinkler system also has FHC (Fire Hose Cabin
   
2.  or Fire Department connection, Usually given at stairs ,  at Landings i.e landing Valves. Fire fighter do flexible connection with them. Its normally Dry system, because it’s for Fire Brigade. Its dry system .
3.                  Fire sprinkler system is standby and its wet system. 24 hours pressurized, whenever a bulb get heat it burst and sprinkler ooze out pump will sense it and will start.  Normally for TANK STORAGE is calculated for  Half Hour system of sprinkling time is designed so that Fire Extinguisher may reach.
4.                 Fire Alarm system is also must. When ever there is a signal and there is chance people can run out escape. Fire Alarm advantage further is , that when there are sensitive system like FM 200 or CO2 systems,is attached , for such areas , the extinguishing powder is humanly unfriendly, so people can escape prior to its activation , 30 sec delay is there . Extinguishing gases finishes the gas, if humans are there , human can die at the spot, so fire alarm initially rings, and cylinder gas is released 20-30 seconds delay in solenoid valve, gas discharge and fire extinguishers, isolated areas , archive,server room, electronic rooms. FM 200 or CO2 dedicated panel also display the location where the fire has erupted.
5.           .       Fire sprinkler system is pressurized . Mall ,Offices ,domestic and Hospital  are low hazardous area, Medium and High are Power Plants , industrial area etc. In software it’s given value accordingly . Always there is 8 bar pressure in sprinkler system. 1bar = 14.5 psi  = 100000 Pascal. Pumps are designed in the way that at least the top building there should be at least 4 bar pressure in wet line.
6.            .    For Calculation of     1 Sprinkler = 12m²  area , for more , more sprinklers are installed.     
7.           .    Sprinklers are taken considering L X W  ( Height is normally assumed 3 meters).  For more than 3 meters height side sprinklers are installed in addition
