BACKGROUND
[0002] Background description includes information that may be useful in
understanding the present invention. It is not an admission that any of the
information provided herein is prior art or relevant to the presently claimed
invention, or that any publication specifically or implicitly referenced is prior art.
[0003] According to high industrial development, there are fire hazards at
places such as general high-storied buildings and factories where a number of
persons are resident or work. Since such fire hazards are increasing and human
casualties or injuries and property damages are huge, sprinklers are installed at
places where a fire may break out in order to inject water into the places where a
fire broke out more rapidly to thus extinguish the fire and thereby prevent the life
and property from disaster in advance. In general, sprinklers are fire extinguishing
facilities that can be recognized as the most excellent extinguishing equipment, in
which sprinkler are installed on the ceilings or walls of an object to be fire
extinguished automatically detect whether or not a fire broke out and discharge
water or gas with a certain pressure, and automatically extinguish the fire.
[0004] However, since these sprinklers are activated in a manner that a
fire is detected by a single signal, malfunction may occur frequently. Further, once sprinklers are operated, the after-measures expenses should be paid highly. Thus, the more frequent malfunctions, the higher after-measures expenses. Accordingly, in many cases, sprinklers may be fabricated so that they do not operate. However, if an accident happens in the case that sprinklers are set so that they do not operate, tremendous damages may be caused. Therefore, we need a system that can accurately detect level of fire and when fire is found beyond a level only then sprinkler can be actuated.

[0005] Nowadays, every building have emergency door and window,
which are generally locked and opened at the time of emergency only. But at the time of emergency people used to be panic, and unable to use technique to open the emergency door. Therefore, a system is required that can open emergency door and window automatically to assist the user to come forth from the building easily.
[0006] There is, therefore, a need in the art to provide a system that can be
used in a premises to detect level of fire/smoke accurately and facilitates in controlling the fire/smoke and assists the person sucked in the premises also that overcomes the above-mentioned and other limitations of the existing solutions and utilized techniques.
