This system combines all the features of the wet pipe, dry pipe and deluge valve system and tends to be used in areas like museums for rare arts, books, antiques etc. Basic difference between a drencher and sprinkler system is that upon actuation all nozzles are activated simultaneously, while in sprinkler systems individual nozzles open one by one.
Drenchsr a building block with 3 or more refuge floors, the water tank capacity will be considered on a case by case basis. Drencher systems shall be installed on all refuge floors to cover all external wall openings.
Drencher water FFFS
If there are two refuge floors in abuilding block, the capacity of the water tank shall be calculated in accordance with the refuge floor with the larger external wall opening area. This type of system is useful where the entire area is affected by fire.
The water flow rate should be maintained not less than 10 litres per minute per square metreof the external wall openings. This page of partial functions have not been able completely to support help disabled persons’ software and the ysstem.
Application Fire protection for: When the fire activates the sprinkler rdencher, there is a drop in pressure that causes the water to flow into the pipes and out through the sprinkler heads. Upon manual or automatic actuation all nozzles are activated simultaneously, in contrary to sprinkler systems where individual nozzles open one by one only in the fire epicenter.
Drencher water FFFS These systems are used for sytem protection of technologies and objects where it is possible to use water as the extinguishing agent.
Fire Sprinkler & Drencher System
The valve will open to allow drenchre to enter the piping system, providing a constant water flow from all sprinklers. There are two types: They are intended mainly for extinguishing, cooling down, preventing the radiant heat from spreading, cooling down surfaces of buildings, steel structures and technological equipment.
The task for drencher water syetem is to prevent spreading of fire to other fire compartments and also they are intended to prevent the radiant heat from spreading and to cool down surfaces of buildings, steel structures and technological equipment. Fire Sprinkler Systems are designed to automatically contain and extinguish a fire. These systems are used for fire protection drencehr technologies and objects where it is possible to use water as the extinguishing agent. Uses both water and foam to spray through the sprinkler.
This system uses deluge valve in the water supply connection. The pipes in this system are filled with compressed air, which are connected to a water main or storage tank with a valve that keeps the water out of the pipes.
Foam Water Sprinkler System: Screening stream is created by screening nozzles with special blade-shaped splitter or nozzles with a slot hole. Drencher systems are used mainly to protect cable objects, building structures, technology equipment, outdoor oil-cooled transformers and stationary tanks for storing liquefied gases. Manual operating device s with operation instruction displayed nearby shall be provided on refuge floor at location s acceptable to the Director of Fire Services.
A deluge value set shall be installed close to the inlet for the drencher system. Independent water tank shall be provided for the drencher system of each building blockwith the capacity to operate for at least 30 minutes. When the heat from the fire gets to a certain temperature the fire sprinkler heads operate spraying water over the fire.

Functions Advantages Application References Servis. This system is charged with water that connects to the sprinkler heads, which activate automatically in case of a fire. They consist of water source, piping, control fittings and nozzles. Protects the window openings in brick wall or combustible cornices from radiant heat in adjacent premises, by discharging water over the entire surface dfencher the glazing or cornices.
Drencher system consists of water source, pump unit, distribution piping, control fittings, alarm device and special nozzles. Such system shall be installed in accordance with standards acceptable to the Director of Fire Services.
This type of system tends to be used in petrol storage, airports, etc.
