What is a fire monitor used for?
A deluge gun, fire monitor, master stream or deck gun is an aimable controllable high-capacity water jet used for manual firefighting or automatic fire protection systems. Deluge guns are often designed to accommodate foam which has been injected in the upstream piping.
What is water monitor in fire fighting?
Monitors can be used to project water or fire fighting foam (or in some cases, even Dry chemical powders). Water monitors typically project only water, while Foam monitors can be used to project water as well as foam.
How does a fire water monitor work?
A monitor system is a fast acting fire protection system used primarily to protect against rapid fire spread in high risk areas. A monitor system controls the flow of water from a water supply to a monitor system using a valve unit and a control system where required.
Is standard for water monitor?
This standard lays down the requirements for stand post type or trolley/trailer mounted water/foam monitor of nozzle size: 63 mm, 75 mrn, 100 mm and 150 mm used for fire fighting at various flow rates. The water foam monitor shall be designed for minimum of 1.2 Nzmm’ rated pressure.
What is a water deluge system?
A deluge fire protection system has unpressurized dry piping and open sprinkler heads. The system is directly connected to a water supply and when the system is activated, a deluge valve will release the water to all the open sprinkler heads. The valve is opened when activated by a heat or smoke detection system.
Why is a water cannon called a monitor?
Lavish attention was paid to the design and specifications of the nozzle and companies began producing their competing appliances. The product names were various — Hoskin’s Dictator and Hoskin’s Little Giant are examples. But the name that stuck was the product name of the Craig Company — the Monitor.
What is a water mist system?
A water mist system is a fire protection system which uses very fine water sprays (i.e. water mist). The small water droplets allow the water mist to control, suppress or extinguish fires by: cooling both the flame and surrounding gases by evaporation.
What is the purpose of a deluge system?
Deluge systems are used in high hazard areas such as power plants, aircraft hangars, and chemical plants. These systems are very effective in hazardous areas because they release water or another fire suppressant to all the open sprinkler heads simultaneously.
Why deluge system is required?
Deluge systems are used in places that are considered high hazard areas such as power plants, aircraft hangars and chemical storage or processing facilities. Deluge Fire Sprinkler systems protect extra hazard occupancies that require significant amounts of water to cool and control the growth or development of a fire.
What are water cannons used for?
Water cannons are water hoses either connected to in-ground water supplies or mobile bladders (often on trucks). They propel streams of high-pressure water aimed at pushing back crowds or low-pressure streams intended to douse.
What is the meaning of water cannon?
A water cannon is a device that shoots a high-velocity stream of water. Typically, a water cannon can deliver a large volume of water, often over dozens of meters. They are used in firefighting, large vehicle washing, riot control, and mining. Most water cannons fall under the category of a fire monitor.
How does a fire water monitor work on an offshore platform?
Oscillating monitors utilize the firewater supply to drive a Pelton water motor to oscillate the monitor in a pre-set horizontal and vertical position without operator interface. Due to the close proximity of the monitor to a fire on an offshore platform the oscillating and remote control design has been preferred.
What can a fire monitor be used for?
Fire Monitors are industrial monitor devices used to deliver large water flows for fire fighting purposes in high risk or hazardous industries. Industrial fixed monitors can be controlled automatically by means of a remote control station.
How does remote control work on a fire water monitor?
Remote operation via remote control panel and electric motors allows an operator to control the monitor in a safe area. Oscillating monitors utilize the firewater supply to drive a Pelton water motor to oscillate the monitor in a pre-set horizontal and vertical position without operator interface.
How big does a fire water monitor need to be?
Firewater monitors are used where it is not practical or desirable for a traditional deluge system with overhead deluge nozzles. Firewater monitors have a large flow capacity (1500 lpm to 7000 lpm+), cover a large area (150m2 – 700m2), and their nozzles are adjustable from a jet to wide fog pattern.
