Abstract
Selecting the proper fire detection and alarm systems requires a careful evaluation of all that the system is designed to accomplish as well as the hazard and the environment in which the detection system must operate. A detection system must fulfill two basic requirements. It must be sensitive enough to detect combustion within an acceptable and required time frame, and it must be reliable enough to not respond to non-fire activation sources. A determination of the proper detection system to use depends on a basic knowledge of the function of the different detectors, the hazard characteristics, and the four stages of combustion. It also must be pointed out that while some systems may be more sensitive to fire and smoke, they may not offer the unique advantage that sprinklers do – water where it is needed and when it is needed.
