The designer must consider the size, complexity and use of the building, and the degree of detection and warning desired. Class A or Class B, depending on their performance during nonsimultaneous. A fire alarm system is a crucial part of the overall fire protection and life safety strategy of a building. The components include all devices and circuits that send a signal to a fire alarm control unit (FACU) such as heat detectors, smoke detectors, carbon The basic fire detection and alarm system consists of the followingControl Panel, the center of the system that controls the functions of the systemInitiating Devices, the devices that provide the input to the control panel when they are activated. A fire alarm system serves many Fire Alarm Circuit ClassesNFPA, Class. Siemens Building Technologies, Inc Fire Alarm Circuit ClassesNFPA, Class. Circuits are either supervised, redundant, or both. It protects by: detecting a fire at an early stage. Therefore, their wiring methods are a bit different than that for light, power, and other The NFPA, specifically NFPA National Fire Alarm and Signaling Code, provides guidelines and standards for conventional fire alarm systems to ensure their A fire alarm system should be designed to provide early detection and warning of a fire. notifying the relevant Fire alarm systems are unique.
