- Abstract
- The equipment which is used for the automatic detection of the fire emergency to function as the automatic fire alarm is installed into the vital areas to perform the important duty of informing inside the building about the accident of the fire emergency. But the main purpose of such an automatic fire alarm system is to discover the fire emergency at the earliest stage and therefore, the part of the equipment known as the detector is very important so far as the detection of the fire emergency is concerned. This automatic equipment must have sensors like the eye and nose of the human to process or detect the smoke or even the heat, etc. to identify the fire emergency. However, the high-precision results of the equipment will certainly depend on its ability to distinguish and decide the fire emergency accurately to differentiate it clearly from the false situations. In any way, it is demanded from the equipment that it should distinguish clearly whether the smoke or heat is coming form the ordinary cooking place or from alarming place with the emergency fire. In many automatic fire alarm systems, discrimination is not achieved accurately and the operation of such signals in the detection-environment causes the false functioning of the fire alarm systems.
