Full title and description

NFPA 72®: National Fire Alarm and Signaling Code, 2022 edition — a consensus standard that establishes requirements for the application, installation, performance, and maintenance of fire alarm systems, emergency communication systems, and signaling systems to protect life and property.

Abstract

The 2022 edition of NFPA 72 provides comprehensive guidance for the design, installation, testing, inspection, and maintenance of fire alarm and emergency communication systems. It addresses detection, notification, emergency communications, supervisory and monitoring functions, system components, and performance criteria. The standard consolidates requirements intended to ensure reliable alarm signaling, prompt occupant notification, and effective interface with fire suppression and emergency response systems.

Scope

NFPA 72-2022 applies to the application, installation, performance, inspection, testing, and maintenance of fire alarm systems and emergency communications systems. It covers systems intended to detect and report fire or other emergency conditions, initiate occupant notification, support emergency communications, provide interface to suppression and building systems, and monitor supervisory and trouble conditions. The document addresses system components, notification appliances, control units, initiating devices, power supplies, circuits, wiring, recordkeeping, and documentation, and gives performance-based and prescriptive requirements for a wide range of occupancies and scenarios.

Key topics and requirements

• Requirements for initiating devices (smoke, heat, manual pull stations) and placement criteria.
• Notification appliance performance, audibility, visual signaling, and installation requirements for occupant notification.
• Emergency communication systems (ECS), mass notification integration, and voice evacuation requirements.
• Notification appliance circuit (NAC) design, power supplies, battery calculations, and survivability requirements.
• System supervision, monitoring, trouble signal handling, and connection to supervising stations or central stations.
• Requirements for inspection, testing, and maintenance schedules and procedures for system reliability.
• Installation practices for wiring, circuit supervision, separation, and compatibility with other building systems.
• Documentation, recordkeeping, system acceptance testing, and commissioning requirements.
• Criteria for special occupancies and hazards, and for integrating alarms with suppression, HVAC, elevators, and life safety systems.

Typical use and users

NFPA 72 is used by fire protection engineers, design and consulting engineers, electrical contractors, alarm system designers and installers, building owners and managers, facilities maintenance personnel, AHJs (Authorities Having Jurisdiction), insurance representatives, and testing/inspection service providers. It is applied in the design and acceptance of fire alarm and emergency communication systems for commercial, institutional, industrial, and residential buildings, and is commonly referenced in building and fire codes and in project specifications.

Related standards

Commonly coordinated standards include: NFPA 101 (Life Safety Code), NFPA 70 (National Electrical Code), NFPA 1221 (Installation, Maintenance, and Use of Emergency Services Communication Systems), NFPA 2001 (Clean Agent Fire Extinguishing Systems), and local building and fire codes. Manufacturer installation instructions and UL/ANSI product standards for fire alarm components (e.g., UL 268, UL 464, UL 1971) are also referenced for component performance and listing requirements.
