Which code addresses the application, installation, location, and maintenance of fire alarm systems?

The code that addresses the application, installation, location, and maintenance of fire alarm systems is NFPA 72. This standard, developed by the National Fire Protection Association, specifically focuses on the requirements and guidelines for fire alarm systems, ensuring they are effectively designed and maintained to provide adequate fire detection and alarm capabilities. It encompasses aspects such as system performance, environmental considerations, testing, maintenance, and personnel training, which are critical for the safety of lives and property in fire emergencies.

In contrast, the other codes listed do not pertain directly to fire alarm systems. For example, NIST 800-53 focuses on security and privacy controls for federal information systems rather than fire safety. ANSI A117.1 addresses accessibility and usability in building design for individuals with disabilities, rather than specifically handling fire alarms. ISO 9001 is a standard for quality management systems applicable to various industries, lacking specific guidelines related to fire safety or alarm system requirements. Thus, NFPA 72 stands out as the relevant code for fire alarm systems.
