General Working Principle:

Detection: Fire detection devices sense heat, smoke, or flames and send signals to the control panel.

Activation: The control panel processes the signals and determines if a fire condition exists. If so, it activates the suppression system.

Discharge: The suppression agent is released through the piping system and discharged through nozzles towards the fire area. 

Suppression: The agent extinguishes the fire by removing one or more elements of the fire triangle (heat, oxygen, fuel).

Types of Fire Suppression Systems:

Wet Pipe Sprinkler System: Water is always present in the pipes, and sprinkler heads activate when exposed to heat.

Dry Pipe Sprinkler System: Pipes are filled with compressed air, and water is introduced only when a fire is detected.

Deluge System: All sprinkler heads are open, and water is released when the system is activated.

Foam System: Produces a foam blanket to smother the fire.

Gas Suppression System: Uses inert gases like carbon dioxide or nitrogen to displace oxygen.

Clean Agent System: Employs environmentally friendly agents to extinguish the fire without damaging equipment.

Additional Considerations:

System Design: The type of system and components are selected based on the specific fire hazards and requirements of the protected area. 

Maintenance: Regular inspections, testing, and maintenance are crucial for ensuring the system's effectiveness. 

Evacuation: Fire suppression systems are designed to control fires, but occupants should still evacuate safely when an alarm sounds.
