What are the two main types of heat detectors?

The two main types of heat detectors are Fixed Temperature and Rate of Rise. Fixed Temperature heat detectors are designed to activate an alarm when the temperature reaches a pre-determined level. This type of detector is especially useful in environments where rapid temperature increases are likely to indicate a fire. Rate of Rise heat detectors, on the other hand, function by sensing a rapid increase in temperature over a given time period. They are effective in detecting fast-developing fires where an immediate response is crucial.

These types are fundamental in fire detection systems as they help in early fire detection, allowing for quicker response times and potentially saving lives and property. Understanding these mechanisms aids in selecting the appropriate heat detector based on the specific fire risk and environmental conditions, ensuring better fire safety management.
