How Exactly Does a Fire Sprinkler System Work?

Fire sprinkler systems are vital in protecting your business, employees, and customers from fires. The system can reduce the risk of property damage, injuries and fatalities. Understanding how a fire sprinkler system works will help you decide on which is the right one for your property:




Fire sprinkler systems can detect a fire through rising temperatures and strategically placed heads with glass bulbs which contain a glycerol-based liquid. This liquid inside the bulb expands when the temperature in the room rises between 135 to 165 degrees Fahrenheit. Once this happens the glass breaks activating the sprinkler system.




Once the glass bulb breaks, the sprinkler will release water which comes through pipes. There are two different ways the water can be stored, wet pipes and dry pipes. With wet pipes the water is released as soon as the trigger breaks whereas in a dry pipe system the water is stored behind a valve that needs to be released before the water can flow through the pipes and out of the sprinkler head.


Pressurized sprinkling


Both the wet and dry pipe systems use pressurized air to distribute the water. In wet pipe sprinklers, pressure in the pipes ensures the water is delivered quickly. In dry pipe and pre-action sprinkler systems, pressurized air is used to fill the pipes instead of water filling them. When a fire is detected the air is released and the water will flow through the pipes.


Post fire


When the fire sprinkler system detects a rise in temperature each sprinkler head will activate only when the fire reaches that sprinkler. If you require a sprinkler system where all the heads go off at the same time you will need to install a deluge sprinkler system. This type of system will activate the water from each sprinkler head once the fire alarm goes off and is mainly used in buildings where flammable or combustible liquids are stored.


Testing and maintenance


In order to comply with the standards and regulations your fire sprinkler systems should be inspected and tested in accordance with NFPA 25. This will mean that you will have to undergo weekly or monthly testing of gauges, alarm devices and control valves as well as bracings, pipes, fittings, and signings. Also every five years, an internal inspection is required.
