The fire detection and warning systems are installed in order to detect a fire that will occur in living spaces early, to warn the people in that area about this situation and to evacuate people properly. In addition, the automatic extinguishing systems are installed in order to eliminate the fire hazard in specific special and/or important areas without expanding.
With the industrialization and the development of technology, early fire detection was possible and warnings were transmitted from one point to another by telegraph in the mid-1800s instead of hand bells or human voices. This process has been started with various electromechanical or electronic sound and/or light warning devices in modern times. The first detectors, bells and control panels were manufactured and started to be used in the USA in the late 1800s.
In the following years, some temperature sensors were used for safety purposes with automatic warning features that were not dependent on humans. These are temperature-sensitive devices such as solder alloy temperature detectors that melt at a specific temperature to open a contact, bimetallic temperature detectors formed by combining two different metal strips with different expansion coefficients, and electro-pneumatic temperature increase rate detectors.
After the 1970s, especially today, systems called conventional fire detection systems have started to be produced. The analogue addressable devices started to be used in the 1980s and the distributed intelligence systems with microprocessors started to be used after the 1990s.
