What is the second type of fire detector?

The second type of fire detector is a heat detector. Heat detectors respond to changes in temperature, activating when a predetermined temperature is reached or if there is a rapid increase in temperature within a given area. This type of detector is particularly effective in environments where smoke or flame detection may not be feasible or could lead to false alarms, such as kitchens or industrial settings where normal smoke or steam may be present.

Heat detectors serve an essential role in fire safety by providing early warning in the event of a fire, allowing for timely evacuation and intervention. They are often used in conjunction with other detection systems, such as smoke detectors and flame detectors, to create a comprehensive fire detection strategy.
