There are several types of fire sprinkler systems, each designed to meet specific needs and building requirements:

Wet Pipe Sprinkler System: The most common type, where pipes are always filled with water. When a sprinkler head is activated, water is immediately released to suppress the fire.

Dry Pipe Sprinkler System: Used in colder environments where pipes are prone to freezing. The pipes are filled with pressurized air or nitrogen, and when a sprinkler head activates, the air is released, allowing water to flow.

Pre-action Sprinkler System: A combination of wet and dry systems. Water is only released after the system has been triggered by both a fire detection device and the activation of a sprinkler head. It is used in areas with sensitive equipment.

Deluge Sprinkler System: These systems have open sprinkler heads, and water is released when the system is activated by a fire detection system. Typically used in high-risk areas.

ESFR (Early Suppression, Fast Response): Designed to quickly suppress large fires in warehouses, it provides a higher flow of water.

Each system is suited for specific environments and risks.
