What does deluge mean in a fire sprinkler system?
A deluge fire sprinkler system, unlike most ordinary systems, mean that the sprinkler heads do not have individual heat-sensitive valves. The sprinkler heads in a deluge system have no valves of their own, meaning they are always open and water will be sprayed out of them when the supply valve is turned on. There are limited uses for deluge systems, such as in a tire storage warehouse where it is important to put out a fire quickly and the massive flow of water will not cause major damage.
What is the difference between deluge and other fire sprinkler systems?
In a deluge system the water comes out of all sprinkler heads at once, compared with most fire sprinkler systems in which each sprinkler head has its own heat-sensitive trigger. There are major design differences in how much water you need for a deluge system and what safety interlocks are built into the system to prevent accidental water damage.
What are the two basic categories of fire sprinkler systems?
Residential and commercial Wet and dry standby Manual and automatic Deluge and sprinkler-head-valved
Should fusible link sprinklers be used in a deluge system?
No, sprinklers in a deluge system are "open"; no valve in the sprinkler, and an automatic valve turns on the water to all open sprinklers when a fire condition is detected.
How a deluge valve system works?
A Deluge System can be activated by the following 1. Manually 2. Electrically (Fire Detectors) 3. Pheumatically (Glass Bulb Detectors) 4. Hydraulically (Glass Bulb Detectors) Each of these methodes (2 3 4) has a fire detection line that can activate the deluge valve Once the Detector operates the deluge valve will be activated, releasing (opening) the water supply to the system. Autommatic Fire Pumps can be activated by this proceedure and inturn extinguish/control the fire condition.
Does a fire alarm set off the sprinkler system?
Most standard fire sprinklers are activated by heat. There's a small bulb of liquid that keeps the water back in the pipes before a fire begins. When a fire breaks out, that liquid will heat up and eventually cause the bulb to burst, releasing the water from behind it.
What is a quick response fire sprinkler?
A quick response fire sprinkler is a fire sprinkler designed to react immediately upon sensing a fire. Typically quick response fire sprinklers are heat activated, where heat from a fire melts a fusible link that allows the fire extinguishant (usually water in the case of fire sprinklers) to put out the fire quickly. Fire sprinkler systems are an important part of a building's total fire protection system, which should also include fire alarms, fire extinguishers and, where appropriate, specialized fire suppression systems.
What is deluge system?
A Deluge System is a fixed fire protection system in which the pipe system is empty until the deluge valve operates to distribute pressurized water from open nozzles or sprinklers.Deluge systems are connected to a water supply through a deluge valve that is opened by the operation of a smoke or heat detection systemDeluge Fire Sprinkler Systems differ from conventional Fire Sprinkler Systems in the sense that all sprinkles or nozzles employed in the system are open and when water is released into the system it flows from all discharge devicesDeluge systems are used in places that are considered high hazard areas such as power plants, aircraft hangars and chemical storage or processing facilities. Deluge systems are needed where high velocity suppression is necessary to prevent fire spread.
Which is the ONLY type of fire sprinkler system that is installed so that all sprinklers are open and spray water when the system activates?
A "deluge" system floods the entire system when sensors detect smoke or heat, and the sprinkler heads do not have individual valves, as would be found in most systems.
How do fire sprinkler systems put out fires?
Fire sprinklers have two major components that operate in response to a fire: the fire sprinkler heads which are connected via a series of pipes to a fire pumps. Water pressure is kept in the head by a series of valves in the pump. and is kept in the heads by little vials of colored liquid. During a fire, the liquid inside the sprinkler heads heats up and starts to expand, eventually causing the vial to burst. Water that was kept in the pipes pours out of the sprinkler heads. The water pouring out of the sprinkler heads causes the pressure in the fire pump to drop. In response, the pump kicks on and pumps more water from the municipal water supply to keep the sprinkler flowing. NOTE: this is how "wet pipe" fire sprinklers, the most common types of fire sprinklers, work. Other sprinklers (dry pipe, deluge and pre-action) are slightly different.
What is the water flow on a fire protection system?
Depends on the system, and it's design. Most standard sprinkler systems are designed for a 30 gallon per minute rate for each sprinkler head. Standpipes and hose lines have other design criteria, as do deluge systems. They ALL take a LOT of water!
What is an example of sentence of deluge?
