Note:

This calculator determines the **required number of FM-200 or NOVEC 1230 nozzles** based on the total hazard volume and the coverage capacity of each nozzle. Proper nozzle placement is essential to ensure even distribution of the suppression agent.

What is a Nozzle?

A **nozzle** is a discharge device that releases FM-200 or NOVEC 1230 into the protected area. Nozzles ensure **even distribution** of the agent, helping to quickly suppress a fire.

Why are Nozzles Important?

• Controlled Discharge: Regulates the flow and velocity of the agent.
• Even Coverage: Ensures the entire area receives proper protection.
• Compliance: Follows NFPA 2001 and ISO 14520 fire safety standards.

Where is this used?

This calculation is used in designing fire suppression systems for **server rooms, data centers, control rooms, industrial spaces,** and other enclosed areas where FM-200 or NOVEC 1230 systems are installed. Nozzles must be properly spaced to ensure the agent reaches all areas efficiently.

Why do we need this calculation?

• Ensures Proper Agent Distribution: Helps determine the optimal number of nozzles required for full coverage.
• Regulatory Compliance: Meets NFPA 2001 and ISO 14520 fire safety standards.
• Prevents Dead Zones: Ensures no areas are left unprotected.
• Optimizes Costs: Helps avoid unnecessary overuse of nozzles, reducing installation costs.

Understanding the Parameters:

• Net Hazard Volume (V): The total volume of the protected space where fire suppression is required (measured in cubic meters).
• Nozzle Coverage Area (N): The volume that a single nozzle can effectively cover, provided by the manufacturer (measured in cubic meters per nozzle).

What does the result mean?

The result indicates the **total number of nozzles required** to ensure proper distribution of the suppression agent. More nozzles are needed for **larger hazard volumes** or **low-coverage nozzles**, while fewer nozzles are required for **high-coverage nozzles**.
