What is a firewater monitor?
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.
How many degrees a fire monitor can move?
Horizontal Rotation of 360 Degrees and Vertical Traverse of +90 Degrees and -45 Degrees.
How many types of fire monitors are there?
Today, there are two types of fire panels: Conventional fire alarm panel; Addressable fire alarm panel.
Are foam monitors different from water monitors?
Water monitors typically project only water, while Foam monitors can be used to project water as well as foam. The monitors projecting foam require special nozzles which allow for induction of foam concentrate (and in the case of aspirated foam nozzles, aereation of the foam solution).
What PSI Do you flow a deck gun?
80 psi
In the case of master stream nozzles, the standard pressure is 80 psi. Unfortunately, the deck gun discharge gauges on fire apparatus do not take their pressure readings at the tip or even at the base of the master stream nozzle.
What is master stream?
Master streams are an effective tool used to fight and suppress fire, especially in defensive situations or when distance must be maintained while pumping large volumes of water. Master streams, like those mounted on a truck or aerial device, are capable of delivering water anywhere from 500 to 2,500 gpms at 100 psi.
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.
Why did submarines have deck guns?
The main deck gun was a dual-purpose weapon used to sink merchant shipping or shell shore targets, or defend the submarine on the surface from enemy aircraft and warships. Typically a crew of three operated the gun, while others were tasked with supplying ammunition. A small locker box held a few ‘ready-use’ rounds.
What pressure do you pump a standpipe?
The minimum pressure while flowing the required standpipe flow (500 GPM from the hydraulically most remote standpipe and 250 GPM from each additional standpipe, up to a maximum of 1000 GPM for a fully sprinklered building) shall be 100 psi at any valve outlet while flowing 250 GPM through each valve.
