Study Notes
Sprinkler Systems
- Wet pipe systems are the most common and easiest to design and maintain.
- Wet pipe systems have water under pressure at all times, and discharge immediately when a sprinkler is activated.
- Dry pipe systems should be used when the temperature of the protected area is below 4°C to prevent freezing.
- Deluge systems are used for facilities that contain combustible or flammable liquids, and discharge large quantities of water over a large area in a short period of time.
- When a fire is detected in a deluge system, the valve opens, and water flows into the piping, discharging from all sprinklers in the system.
Preaction Systems
- Preaction systems are used in environments that house computer equipment or communication equipment, museums, and other facilities where inadvertent water discharge must be avoided.
- Preaction systems combine the benefits of dry pipe and deluge systems.
- The purpose of a preaction valve is to delay water flow into the piping until a fire is detected.
- The supplemental detection system in a preaction system provides additional detection capabilities to ensure that the system operates only when a fire is present.
Antifreeze Systems
- Antifreeze systems are used in areas where the temperature is below 4°C to prevent freezing.
- The purpose of antifreeze systems is to prevent freezing in the piping.
Dry Pipe Systems
- Dry pipe systems are used in areas where the temperature is below 4°C to prevent freezing.
- The purpose of a dry-pipe valve is to prevent water from entering the piping until a fire is detected.
Check Valves
- The purpose of a check valve in a sprinkler system is to prevent water from flowing backwards in the piping.
Applications
- Wet pipe systems are commonly used in office buildings, stores, manufacturing facilities, hotels, and health care facilities.
- Deluge systems are commonly used for facilities that store hydrocarbon products, such as propane.
- Preaction systems are used in environments that house computer equipment or communication equipment, museums, and other facilities where inadvertent water discharge must be avoided.
- Dry pipe systems are used in deep-freeze facilities where accidental preaction valve opening would cause frozen water pipes in a very short time.
