What are the four types of sprinkler systems?
Table of Contents
Today, there are four main types of sprinkler systems:
- Wet pipe.
- Dry pipe.
- Preaction.
- Deluge.
What type of sprinkler system would be in a heated warehouse?
Wet Pipe Sprinkler System This is the most common type of fire sprinkler system. The pipes in the facility constantly have pressurized water stored, ready to discharge upon activation. The sprinkler heads are activated by heat, and additional heads may be activated by heat and discharge, as well.
What types of fire sprinkler systems are most likely installed in this building?
Wet Pipe System Wet pipe sprinkler systems—or traditional fire sprinklers—are the most common across residential and commercial buildings.
What are the most common sprinkler designs typically found in commercial buildings?
Wet pipe fire sprinklers constantly have water in them. This allows for a quick reaction to a fire and is the most common type of sprinkler installed in buildings. A type of building that uses the wet pipe system is a high-rise or office building with a few floors.
What is a preaction sprinkler system?
Pre-action fire sprinklers are a dry sprinkler system, water is not contained in the pipes but is held back by a pre-action valve. Pre-action valves are electrically operated valve that is activated by heat, smoke or flame.
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 K factor for sprinklers?
discharge coefficient
The k-factor for a fire sprinkler is the discharge coefficient, or in normal human terms just relates to the amount of water that is permitted through the sprinkler. The k-factor is dependent upon the orifice diameter of the sprinkler – a low k-factor (such as K2.
Why is NFPA 13 important?
The purpose of NFPA 13 is to provide a reasonable degree of protection for life and property from fire through standardization of design, installation, and testing requirements for sprinkler systems (including private fire service mains) based on sound engineering principles, test data, and field experience.
