Water Suppression Systems
Sprinkler systems are a simple yet effective method of fire protection for residential or commercial projects. The system consists of a water source and piping that connects it to sprinkler heads installed on the ceiling and walls. Pumps are used to transport water from the source to the sprinkler heads.
WHAT IS A SPRINKLER HEAD?
- The sprinkler head is a type of nozzle that opens with heat during a fire and sprinkles the water in the system onto the flames.
- It performs both extinguishing and detection tasks at the same time.
- Each Sprinkler head contains a heat-activated mechanism. The Sprinkler head opens when this mechanism is activated.
- Different Sprinkler detection mechanisms are designed around criteria such as application site and fire hazard class. This mechanism that keeps the sprinkler head closed can be a metal that melts at low temperatures and is made of a combination of bismuth, lead, tin, and cadmium, or it can be a small glass tube that explodes when the glycerine-based liquid expands in the event of a fire.
- Sprinklers are classified into three types that shoot in different directions: upright, pendent, and sidewall. Since they disrupt the visual design of the environment, pendent sprinkler heads are sometimes placed inside the suspended ceiling and covered with special covers that open in case of fire. These are called “Concealed Type Sprinklers”. Wall-mounted Sprinkler heads are placed at a high point on the wall and can protect larger areas than other Sprinkler types.
- Sprinkler heads are activated independently of each other. Only the sprinkler heads in the fire area are turned on.
- They need less water and are more efficient than fire hoses.
SPRINKLER SYSTEM TYPES
Automatic sprinkler extinguishing systems are divided into four different categories:
- Wet: In this system, which is commonly used in residential buildings, cold water is kept in the pipes under certain pressure and is discharged onto the fire as soon as the sprinkler heads are opened.
- Dry: A dry type activates later than a wet type and is used in unheated or unmanned locations where water may freeze. The pipes contain nitrogen or pressurized air instead of water which eliminates the possibility of water freezing in the pipes. Nitrogen and pressurized air are discharged first from the Sprinkler heads that are opened in the event of a fire, and then the fire pump begins to send the water in the tank to the system, and the water is discharged onto the fire.
- Deluge: They were designed exclusively for areas where a fire might spread too quickly. In these systems, sprinkler heads are always on. The system is activated by a separate mechanical or electrical detection system, and water is discharged from all Sprinkler heads in the system, not just those in the fire area.
- Pre-Action: They are used in locations where water can cause damage and where valuable items are stored (archives, museums, galleries, etc.). It is a kind of combination of Wet and Dry type systems. Double detection is used to prevent false detections.
