What is the maximum Rate of Temperature Increase (RTI) for detectors?

The maximum Rate of Temperature Increase (RTI) for detectors is established to ensure that fire detection systems operate effectively while providing a balance between sensitivity and reliability. An RTI of 100 indicates that the detector is designed to respond optimally to changes in temperature that occur at this rate, allowing for early detection of potential fires without being overly sensitive to other temperature fluctuations.

Detecting a fire quickly when the temperature increases at or below this rate helps in preventing possible damage and ensuring safety. Setting the RTI too high could lead to late detection in critical situations, while setting it too low might result in false alarms from non-threatening temperature changes.

The other values do not represent the standard maximum RTI for effective fire detection systems, which is why they are not correct in this context. By maintaining the RTI at an appropriate level, fire detection systems can perform their essential role in safety and early warning effectively.
