There are several types of fire sprinklers, each designed for specific fire suppression needs and building requirements. The primary types include:

Wet Pipe Sprinkler System:

Most Common: Water-filled pipes are always under pressure and immediately discharge water when a sprinkler head activates.
Advantages: Simple, reliable, and fast response time.
Best for: Offices, residential buildings, and warehouses.
Dry Pipe Sprinkler System:

For Cold Environments: Pipes are filled with pressurized air or nitrogen, and water only enters when the system is triggered.
Advantages: Prevents freezing in cold climates.
Best for: Unheated areas, such as attics or outdoor buildings.
Pre-Action Sprinkler System:

Two-Stage Activation: Requires both heat detection and sprinkler activation before releasing water.
Advantages: Reduces accidental activation, ideal for sensitive areas like data centers.
Best for: Museums, archives, and electronic equipment rooms.
Deluge Sprinkler System:

Open Sprinkler Heads: All sprinklers activate simultaneously when a fire detection system is triggered.
Advantages: Releases large volumes of water for high-risk areas.
Best for: Chemical plants, aircraft hangars.
ESFR (Early Suppression, Fast Response):

High-Flow: Designed to quickly suppress large fires, providing early detection and rapid water discharge.
Advantages: High flow rate for large-scale fires.
Best for: Large warehouses and storage areas.
Sidewall Sprinklers:

Wall-Mounted: Installed along walls, these sprinklers are ideal for narrow spaces where ceiling installation is not possible.
Advantages: Effective in spaces with limited ceiling height.
Best for: Corridors, hallways, and small rooms.
Each type of sprinkler system is chosen based on the building’s environment, potential fire risks, and local safety regulations to provide optimal fire protection.
