The main purpose of these systems is to quickly respond to the fire and then convert this early response into an audio and visual signal to alert individuals in the building, place, relief or fire center that there is a fire in its early stages, and the fire alarm is considered to mitigate the severity of fires and the damage resulting from them because they allow them to be controlled quickly through early warning, so alarm detectors of various kinds are designed according to the nature of the sites and the type of fire. The fire system consists of a control panel and detectors Fire, bells, call buttons, wire network and pipes that connect the system to each other.
What are the stages of fire?
The first stage "primary": The fire has no smoke or smell, it begins to form and is small in size and is not observed and uses flame detectors when the desired place is of paramount importance, such as oil depots, production places and manufacturing places.
The second stage: It is the one in which smoke begins to form and the fire begins to appear and smoke detectors are used.
The third stage: flames begin to appear and smoke rises, which is the stage in which the fire alarm is felt and heat detectors are used.
The fourth stage: in which the fire develops to its maximum degree and has a rapid spread and must be eliminated before it continues during this stage, and in this case the fire systems work to control the fire.
