FIRE INSTALLATION

Fire Installation; It is established in order to keep the fire under control until the fire brigade intervenes in a fire that may occur, to ensure the safe evacuation of people from the environment, and to support the fire extinguishing personnel during the fire. Hazard Classification is made in buildings according to their characteristics and building activity status. Threaded fire pipes are generally used inside the building, and welded or grooved, coupling fire pipes from 2" onwards. Although the pipe system with grooved coupling is costly, it is preferred in some places because it is clean and safe. Insurance companies are now more meticulous about fire installation. In some projects, fire equipment is required to be UL/FM approved and NFPA compliant.Fire connection valve is used on facades exceeding 60m.Water type Fire extinguishing systems Sprinkler System / Sprinkler System; Established to extinguish the fire, provide cooling, and keep the fire under control until the firefighter arrives. are automatic extinguishing systems inside the building that spray water when it reaches the design temperature.In non-residential buildings with a building height exceeding 30.5 m, In all buildings with a building height exceeding 51.5 m, In parking garages larger than 600 m2, 2000 m2 It is used in public use areas larger than . ace is mandatory. As the area grows, it should be divided into zones. The valves used are with monitoring switches and can be connected to automation. Sprinkler installation includes Wet Alarm Valve, Butterfly Valve with Monitoring Switch, Test Drain Valve, Flow Switch. Fire cabinet; They are generally indoor manual fire extinguishing elements with 20m, 25m or 30m hose, tube or tubeless, flush mounted or surface mounted, cloth or rubber hose. 100 lt/min flow rate is calculated for 1 cabinet. There are also foamed types of fire cabinets. Fire Hydrant; It is an outdoor manual fire extinguisher. It is used with a hydrant cabinet with a hose (sahara type) next to it. Fusion welded HDPE pipe is usually installed between hydrants. Pipes are buried 80-100 cm deep in the field. According to fire hazard class min. 1900 lt/min flow rate is taken as basis. The distance between the hydrants can be 50-150 m depending on the fire hazard class. There are aboveground and underground types of hydrants and different sizes. Fire pump; A pump set consisting of 1 electric, 1 diesel and 1 jockey is used. If there is a generator strong enough to run one pump in the building, an electric pump can be used instead of a diesel pump. The Fire Booster set has an automated panel. Once a week the system should test itself. There is a water tank in the system with a capacity to supply the pump with uninterrupted water for 1 hour. Large water tanks are preferred for construction. Foamy, Gaseous Fire Extinguishing Systems; This type of extinguishing systems is preferred in places where the extinguishing ability of water is insufficient, there are substances that can react with water or where water should not be used. Hood extinguishing systems; It is used in kitchens. There are fusible wire sprinklers inside the hoods, these nozzles are connected to the CO2 tube with a copper pipe. Stair pressurization; The stairwell is pressurized for human escape. Fire doors should also be included in the project. Indoor Parking Ventilation; Mechanical Ventilation is mandatory in parking garages with a total area of more than 2000 m2. Smoke evacuation system is installed with 10 changes per hour. Suction is made both from the ground and from above. Jet fans; Jet fans can also be used as an alternative to the ducted smoke evacuation system in closed parking lots. They have radial and axial types. It is used in ventilation with low speed in normal time, it works at high speed in case of fire.
