The devices then send a signal to the facu using one of two methods. A hard wire system or a generated signal conveyed by radio wave over a special. The designer must consider the size complexity and use of the building and the degree of detection and warning desired. The first assessment shows a detection layout with generic flame detectors with 25m detection distance to the 1ft pan fire with a generic risk volume grade requiring detection of a 50kw fire.

A fire detection system consists of manual and automatic alarm initiating devices that are activated by the presence of fire smoke flame or heat figure 14 6. Fire is continuous oxidation of combustible material in exothermic chain reaction between fuel and oxygen or oxidiser or air as catalyst when exposed to sufficient amount of heat or ignition source giving out smoke heat light energy in the form of electromagnetic spectrum and other by products. Multi detector combination of smoke and heat. F g systems include offshore petroleum exploration and production onshore oil and gas facilities refineries and chemical plants marine operations tank farms and terminals pipelines power plants mining and paper mills.

The detector locations are representative of a layout based on practical mounting locations. A fire alarm system should be designed to provide early detection and warning of a fire. Fire and gas detection system by ismail ali mohamed 2.
