A fire sprinkler system is a system which releases water from sprinklers which are usually automatically activated when a rise in temperature is detected. These systems can commonly be found in commercial and industrial spaces such as offices, warehouses or factories. Sprinkler systems are also widely used around the world as a form of fire protection.
When a fire starts in a factory or warehouse leading to a rise in temperature, sprinklers are usually activated one sprinkler at a time.
Smaller fires usually require just a few sprinklers to extinguish and sprinklers are usually not triggered all at the same time.
Discharge rate and response time index or RTI of various types of sprinklers may vary.
