Which code governs the installation of fire alarm systems?

The installation of fire alarm systems is governed by NFPA 72, which is also known as the National Fire Alarm and Signaling Code. This code provides specific requirements for the design, installation, performance, and maintenance of fire alarm systems, ensuring that they provide effective warning and notification in the event of a fire emergency.

NFPA 72 covers a wide range of systems and components, including their location, spacing, and placement to ensure optimal detection and alarm functionality. Adherence to this code is crucial for compliance with fire safety regulations, and it helps in minimizing risks associated with fires by ensuring that alarm systems function as intended to alert occupants in a timely manner.

In contrast, NFPA 70 refers to the National Electrical Code, which focuses on electrical safety and wiring requirements but does not specifically address fire alarm systems. NFPA 101 outlines life safety in buildings but does not deal with the technical specifics of fire alarm installations. NFPA 15 pertains to water spray fixed systems for fire protection and does not encompass fire alarm systems. For these reasons, NFPA 72 is the correct code that governs the specific installation requirements for fire alarm systems.
