A fire sprinkler system is an active fire protection measure, consisting of a water supply system, providing adequate pressure and flow rate to a water distribution piping system, onto which fire sprinklera are connected. Over the year, fire sprinklers have become mandatory safety equipment in most part of India, in certain occupancies like newly constructed hospitals, schools, hotels and other public buildings, Industries, etc. Subject to the local building codes and enforcement. Sprinkler may be required to be installed to reduced potential property losses or business interruption. Each sprinkler activates independently when the predetermined heat level is reached. Because of this, the number of sprinklers that operate is limited to only those near the fire, thereby maximizing the available water pressure over the point of fair origin. Fire Sprinkler System have been the biggest breakthrough in fire protection in the last 100 years. Fire sprinklers are the most effective method of protecting lives and property. Sprinkler system are now recognized as being so effective they are being made mandatory in many situations.
