Chapter 9 - Fire Alarm and Mass Notification Systems

Abstract

This chapter deals with fire alarm systems deployed in buildings. Fire alarm systems are the primary life safety system for every building; properly deployed, a fire alarm system reduces the probability of injury or loss of life and limits damage due to fire, smoke, heat and other factors. Because of their criticality, the codes, regulations, and standards affecting the design and installation of fire alarm systems are wide ranging and detailed. Their design and installation must involve qualified, licensed, experienced professionals, and, more important, the coordination and approval of the local authority having jurisdiction (AHJ). The two main organization addressing codes and standards for fire alarm systems are the National Fire Protection Association (NFPA) and Underwriters Laboratories (UL). Given their life safety nature fire alarm systems are starting to utilize IP-based functionality and should be integrated with other systems within a smart building. The integration to other systems plays a critical role in minimizing the effects of the fire. A fire alarm system will initiate communications to other building automation and security systems to facilitate evacuation from the building and containment of the fire.
