The Development of Operation Algorithm of Heat Detector with Variable Response Parameters

It has been identified that there are objects where ambient air temperature changes not only as a result of a fire, but also due to the operation of technological equipment and harsh climatic conditions. These changes affect the timing of work for the fire detector. These facilities include boiler rooms, kitchens, dryers, vehicles, etc. The article substantiates the need to develop a heat detector that would change its response parameters and at the same time would not contradict the regulatory requirements for its class. There have been proposed algorithms for the operation of a heat detector which changes the value of the static response temperature and the rate of rise temperature at which it responds. The algorithm of operation analyzes the speed of raising the ambient temperature without information about the operating modes of technological equipment and sets new values of the response based on the analysis.
