Wet Pipe System:
It is a system consisting of automatically operating water sprinkler heads, connected to a network of pipes filled with water
It is connected to a reliable water source, so that water flows directly from the head or heads that have been affected
By heat resulting from fire.
The wet system is used as an extinguishing system in occupancies and spaces where the temperature is low
Normal, i.e. not too cold or too hot (water temperature not less than 4°C and not more).
Above 70°C (or systems that require a pressure not exceeding 12.1 bar.
Dry Pipe System:
It is a system consisting of automatically operating water sprinkler heads, connected to a network of pipes filled with air or
Compressed nitrogen, in the event of a breakage of the bulb of one of the sprinkler heads as a result of a high temperature
The temperature of the space in which it is installed, this leads to an explosion of the compressed air or nitrogen present
In the network, it is followed by a flow of water that is present in the network between the pumps and the dry valve, where it opens
The dry valve is a result of the difference in pressure and thus the network is filled with water that flows from the sprinkler head or
Open sprinkler heads.
The dry system is used as an extinguishing system in occupancies and spaces prone to freezing, such as refrigerators
Freezers or in high-temperature occupancies, such as ponds (the water temperature is less than…
4°C or more than 70°C (or systems that require a pressure of more than 12.1 bar, as well as systems
The temperature of the water in the system exceeds 49°C
Preaction System 🙂
It is a system consisting of automatically operating water sprinkler heads, connected to a network of air-filled pipes
Compressed or uncompressed, with an automatic alarm system connected to a main control panel, so that…
Automatic alarm system components (heat, smoke or flame detectors) in the same protected area
With water sprinkler heads, and when the alarm system is activated, it sends a signal to the driver valve to allow this
The valve in turn allows water to pass through the pipe network and then flow from any sprinkler head or sprinkler heads
Open as a result of being affected by the heat in the space in which it is installed.
The pre-emptive system is used as an extinguishing system in occupancies where there is a risk of a sudden influx of water
As a result of sprinkler heads being exposed to factors other than temperature, or in occupancies containing objects
It is of high value as this system can be placed in computer rooms, laboratories, libraries and public buildings

Deluge System:
The system consists of open water sprinkler heads (without bulbs) connected to a network of pipes supplied from a source
Water through a valve called the flood valve, which is opened by the action of the alarm system located in the space
Itself is protected by a submergence system, where water flows into the pipes and exits from all piped heads
the system.
The complete submersion system is used as an extinguishing system in occupancies and spaces that require large quantities
of water to extinguish in a short time, and in jobs in which the speed of ignition of materials is high, such as
Liquefied gas tanks, flammable liquids, aircraft hangars, and electrical transformers, the warning system shall be
The one that operates the immersion valve is either mechanical using water or mechanical using air or
Using electricity.
