Heat Detector

A heat detector is a device that is used to detect and respond to changes in temperature. It is commonly used in fire alarm systems to detect the presence of a fire or excessive heat. Heat detectors are designed to activate an alarm when the temperature in the surrounding area reaches a certain threshold.

There are different types of heat detectors available, including fixed temperature detectors and rate-of-rise detectors. Fixed temperature detectors are set to activate when the temperature reaches a specific level, typically between 135 to 190 degrees Fahrenheit (57 to 88 degrees Celsius). Rate-of-rise detectors, on the other hand, are designed to detect a rapid increase in temperature, such as the temperature rising more than 15 to 20 degrees Fahrenheit (8 to 11 degrees Celsius) per minute.

Heat detectors are often used in areas where smoke detectors may not be suitable, such as in kitchens or garages, where cooking fumes or exhaust fumes can cause false alarms. They are also commonly used in industrial settings where high temperatures are present, such as in manufacturing plants or storage facilities.

It is important to note that heat detectors are not a substitute for smoke detectors, as smoke detectors are more effective at detecting fires in their early stages. However, heat detectors can provide an additional layer of protection in certain environments where smoke detectors may not be suitable or reliable.
