Seven Types of Sprinkler Systems
Did you know that there are seven different types of sprinkler systems used in commercial buildings? Or that heat causes a system to activate? Below are the seven systems and how they work.
Wet Pipe System
This is the most common sprinkler system in commercial buildings. In this system water is continually moving through the pipes so that when the system is activated it is immediately released.
Dry Pipe Systems
This is the second most common sprinkler system. This is used in buildings which do not have heat. It is set up this way so that water does not sit in the pipes and freeze when the cold weather comes in. It would be counter intuitive. Air pressure is used instead of water. Once a sprinkler head is activated the air is released and water is moved through the pipes to be dispersed.
When this system is activated water is released from all sprinkler heads at the same time. These are usually placed in areas where there are high risks of fire.
This system is placed where you don't want it to have an accidental activation. This could be in museums or computer labs. There are also two types of pre-action systems, single interlocking and double interlocking.
Single interlockings design is similar to the dry pipe system. However when activated is converted into a wet pipe system to help reduce the delay of the was being distributed.
Double interlocking is similar in design to the deluge system. However this system has automatic sprinkler heads. You also need two detection systems to be activated.
Foam Water Sprinkler System
This system releases a mixture of water and foam when activated. This would be best in a science lab that deals with flammable liquids.
Water Spray System
This is similar to the deluge system, however it is designed to protect a certain area or piece of equipment.
Water Mist System
Is a system that used mist to cool and extinguish fires in older historic homes or office buildings.
