Which NFPA standard lists system classifications for fire alarm systems?

The National Fire Protection Association (NFPA) standard that lists system classifications for fire alarm systems is NFPA 72. This standard, known as the National Fire Alarm and Signaling Code, outlines the requirements for the installation, performance, and maintenance of fire alarm systems, including classifications for different types of fire alarms and their functionalities. Understanding these classifications is crucial for ensuring that fire alarm systems are designed to meet specific safety needs and operational requirements.

NFPA 70 pertains to electrical installations and the National Electrical Code, which does not address fire alarm system classifications. NFPA 25 deals with the inspection, testing, and maintenance of water-based fire protection systems, which is not relevant to fire alarm systems. NFPA 101 is the Life Safety Code, focusing on building occupancy and safety, but it does not specifically classify fire alarm systems. Therefore, NFPA 72 is the appropriate standard for this topic.
