To detect heat from/of a fire or something which is dangerously hot in cerrtain apllications. They are connected to fire alarm system where when the heat detector detects heat, it activates the fire alarm causing the need to evacuate. These type of devices are used in applications where smoke detectors would not be practicle. For example, kitchens, boiler houses etc.

What is the function of evaporator in refrigeration system?
an evaportor is to absorb heat in the room and to keep it cool,to release the hot air outside in the atmosphere
What is heat rejection?
The heat of rejection, also known as just heat rejection, is when heat leaves a system. How much heat is lost depends on the system and its functionality.
What is difference between path function and point function in thermodyanaMICS?
Path function: Their magnitudes depend on the path followed during a process as well as the end states. Work (W), heat (Q) are path functions.The cyclic integral of a path function is non-zero. work and heat are path functions.Point Function: They depend on the state only, and not on how a system reaches that state. All properties are point functions.The cyclic integral of a point function is zero. properties are point functions, (ie pressure,volume,temperature and entropy).
How is heat capacity a path function?
Heat capacity is NOT a path function. It is a STATE function. It depends on the phase of the material, the temperature and the pressure. Usually heat capacity is known at some particular condition and then a calculation is required to estimate it at the condition of interest. Performing these calculations should always result in the same final value no matter the path you took to get to the value - hence it is a STATE function rather than PATH. Path functions would be things like WORK and HEAT (for which the state function "heat capacity" might be used in the calculations)
What is the main function of a cooling unit in a refrigeration system?
The basic function of a cooling unit is to warm up the contents of the system.
What is a heat detector?
A heat detector is connected to a fire alarm system. It is designed to respond when the heat sensitive element has increased temperature due to a fire.
Do pets cause interference with ademco heat detectors?
I am not personally familiar with the ademco heat detector, but I have done some research and have found that this head detector is pet immune, and pets do not cause interference with this heat detector security system.
What is the function of diode detector?
the function of a diode detector is to detect stuff
What is the distance between heat detectors?
5M Detector to Detector
What is the function of a Chubb detector lock?
A Chubb detector lock has a integral security system which if attempted to be picked causes frustration for the criminal and alerts the owner of the lock that it has been tampered with.
What is the function of detector in UV spectrophotometer?
Detector converts optical signal to electric signal
How far is Ottawa from Vancouver appoximately?
first optical smoke / heat detector to second optical smoke/heat detector maximum distance.
What are the benefits of owning a heat detector?
A heat detector is a good addition to the smoke alarm. It will help to detect a heat source that is growing in case the smoke alarm in the home is not functioning.
Can you use a heat detector in dried sauna?
no
What is the most sensitive heat detector?
A Bolometer.
Why isn't heat a state function?
a state function basically asks "does it matter how I get there". Heat is not independent. It depends on the system and surrounding, as well as other factors.
Can a smoke detector sound from heat only?
Then it wouldn't be a smoke detector, but there are fire alarms that are triggered by temperature.
