What are the three types of sprinkler?
3 Types of Fire Sprinkler Systems
- Wet Fire Sprinkler System. A wet fire sprinkler system is one of the most common options on the market.
- Dry Fire Sprinkler System. A dry fire sprinkler system is filled with pressurized air, rather than water.
- Preaction Fire Sprinkler System.
What are the two main types of sprinkler systems?
Sprinkler system types
- Wet pipe systems. Wet pipe sprinkler systems are the most common system.
- Dry pipe systems. Dry pipe systems are installed in spaces where the ambient temperature may be cold enough to freeze the water in a wet pipe system, making a wet pipe system inoperable.
- Deluge systems.
- Pre-action systems.
What is a Class 4 sprinkler system?
Class IV — This class includes Class I, II, or III products and packaging containing a significant amount of Group A plastics (5-15 percent by weight or 5-25 percent by volume) stored in ordinary corrugated cartons with or without Group A plastic packing, which may be stored with or without the use of pallets.
What is the most common type of sprinkler system?
Wet pipe systems
Wet pipe systems are the most common type of fire sprinkler systems. These systems are filled with water from an automatic source, and when a sprinkler head is exposed to enough heat, the heat-sensitive element will release and water will be allowed to flow from that sprinkler.
What is the difference between NFPA 13 and 13R?
While NFPA 13 is applicable to a variety of commercial buildings—both residential and nonresidential—NFPA 13R is essentially only applicable to low-risk residential structures that consist of four stories or less.

Types of sprinkler systems • Wet • Dry • Deluge • Pre-action • Water Mist Wet Pipe Sprinkler Systems • A wet pipe sprinkler system uses automatic sprinklers attached to a piping system filled with water and connected to a water supply so that water discharges immediately from sprinklers opened by heat from a fire
What is a wet pipe sprinkler system?
• A wet pipe sprinkler system uses automatic sprinklers attached to a piping system filled with water and connected to a water supply so that water discharges immediately from sprinklers opened by heat from a fire • Most common type of system • Used for buildings where there is no risk of freezing
What is the difference between dry pipe and sprinkler systems?
When a sprinkler head is activated by the heat from a fire water flows immediately on to the seat of the fire. Dry pipe systems are installed in premises where there is a possibility of water in pipes freezing.
What are the requirements for sprinkler systems?
– Application of sprinkler types • Requirements may vary depending on type of system used • For any system, pre-lubed grooved couplings are recommended Wet Pipe Sprinkler System Requirements • Must be reliably heated. Overhangs and
