1. Wet Pipe Sprinkler System:
This is the most commonly used sprinkler system in commercial and residential buildings. As the name suggests, this system uses pipes that are constantly filled with water. When a fire breaks out, the sprinkler heads in the affected area automatically spray water, effectively controlling and extinguishing the fire.

2. Dry Pipe Sprinkler System:
In this system, the pipes are filled with pressurized air or nitrogen instead of water. The sprinkler heads are connected to the pipes via a dry valve that keeps the water from entering the pipes until a fire activates the sprinkler heads. When a sprinkler head is triggered, the dry valve releases the air, allowing water to flow through the pipes and onto the fire.

3. Pre-Action Sprinkler System:
This system is a combination of wet and dry pipe systems. It uses pressurized air or nitrogen in the pipes, but the sprinkler heads are not constantly filled with water. Instead, the system requires both a fire detection system and the activation of a sprinkler head for water to flow through the pipes. This makes it suitable for areas with valuable equipment or sensitive materials that may be damaged by accidental water discharge.

4. Deluge Sprinkler System:
In this system, all the sprinkler heads in a building are open and connected to water pipes that are constantly filled with water. The system is activated by a detection system, which opens a valve to release a large amount of water onto the entire area or room. This system is commonly used in high-risk areas such as chemical storage facilities and power plants.

5. ESFR (Early Suppression Fast Response) Sprinkler System:
This type of sprinkler system is designed specifically for high ceiling areas, such as warehouses. The sprinkler heads are spaced further apart compared to other systems and are designed to release a large amount of water at a high velocity, effectively controlling fire in a large area.

In conclusion, choosing the appropriate type of sprinkler system for a building depends on various factors, including building design, occupancy type, and fire risks. It is essential to consult with a professional engineer or fire protection expert to determine the most suitable type of sprinkler system for a specific building.
