NFPA 731-2026

NFPA 731 Standard for the Installation of Premises Security Systems, 2023 edition

The purpose of this standard is to define the means of signal initiation, transmission, notification, and annunciation; the levels of performance; and the reliability of premises security systems. This standard addresses the integrity and reliability of cyber intrusion protection for equipment or systems network connected to the Internet of Things (IoT). This standard defines the features associated with these systems and also provides information necessary to modify or upgrade an existing system to meet the requirements of a particular application. This standard establishes minimum required levels of performance, extent of redundancy, and quality of installation but does not establish the only methods by which these requirements are to be achieved. This standard shall not be interpreted to require a level of premises security other than that required by the applicable codes and standards.
