The following system design process is intended to give a reasonable overview of all the areas of knowledge required for the successful design of a fire alarm system. Due to the complex nature of legislation and design standards relating to fire alarm system design, this course is not intended to be a comprehensive to all aspects of fire alarm design but rather a very useful source of background information to which further application specific detailed information can be added from other sources as required.  \nWhy have a fire alarm system?  \nThe answer to this question depends on the premises in question and the legal requirements. Your local fire marshal may require a fire alarm system based upon the occupancy of the building. Generally the legal requirement for a fire alarm system relates to the protection of life. In general fire alarm systems are installed to:  \n1. To provide for the safety of occupants in buildings, and to make provision for their evacuation or refuge during a fire or other emergency,  \n2. To provide fire department with early notification of a fire in a building and to direct them to the area of risk,  \n3. To reduce loss of property; the property may have considerable intrinsic value and the insurers either require a fire detection system or may incentives its use,  \n4. To reduce building damage; the building may be unoccupied for periods where equipment is still powered and the owner wishes to ensure that if anything goes wrong the fire department is called to the scene in a timely manner. Sometimes fire detection and alarm systems are used to compensate for structural fire protection shortcomings or to give special cover for items of high value,  \n5. To reduce the amount of business lost, and  \n6. Minimize risk to the public who attend unfamiliar properties. It is often a mandatory requirement by the Building Codes.  \nWhatever the reason, an automatic fire detection and alarm system generally provides a network of manual call points, heat and smoke detectors, and alarm warning devices over the area covered. Once activated, the devices send signals to the fire alarm panel which in turn activates audio and visual devices including lights and sounders. The system may also send its signal to an off site monitoring station.  \nRISK ASSESSMENT  \nThe first step in the design process is the risk assessment. It underpins the whole system strategy and therefore could be argued as being the most important stage. Risk assessment is the process of considering each part of a building from the point of view of what fire hazards exist within an area and what would happen in the event of fire or if explosion were to occur. This would normally be done when considering the building from the point of view of general safety. Clearly very small premises only require a first level of fire protection, such as safe construction, clear escape routes and a fire extinguisher. Equally obviously, large hotels will require a fully automatic fire detection and alarm system, multiple sets fire protection equipment and adequate emergency lighting and escape signage. The Risk Assessment process is to help building owners of buildings between these two extremes make adequate and appropriate provision. Building owners or operators will often want to employ the services of a professional risk assessor to ensure that the building is considered impar","cbCaij4hAEZMvcjW","https://ap.wps.com/l/cbCaij4hAEZMvcjW","pdf",363932,"English","# Why have a fire alarm system?\n# Risk assessment\n# Consult with all interested parties\n# Design process\n# Review of the Building\n# Fire compartments","[{\"question\":\"Why are fire alarm systems installed in buildings?\",\"answer\":\"They protect occupants by supporting evacuation or refuge, provide early notification to the fire department, reduce property and building damage, limit business interruption, and minimize risk to the public where required by building codes.\"},{\"question\":\"What does the risk assessment step involve?\",\"answer\":\"Risk assessment considers fire hazards in each building area and what would happen in the event of fire or explosion.
