Note:

This calculator helps determine how quickly a heat detector will respond to a fire. The response time is influenced by the detector's design and the movement of hot gases.

Understanding the Parameters:

• Response Time Index (RTI): A measure of how fast the heat detector responds to temperature changes. Higher values indicate slower response times.
• Hot Gas Velocity (V): The speed at which hot gases move in the environment, affecting how quickly the detector activates.

How the Calculation Works:

The response time of a heat detector depends on its RTI and the velocity of the hot gases. A higher gas velocity results in a faster response time, while a higher RTI indicates a slower response.

Enter the **RTI value** and **hot gas velocity** to calculate how quickly the heat detector will activate in case of a fire.
