NZS 4512:2021
Fire detection and alarm systems in buildings
Standard provides a complete specification for the design, manufacture, installation, documentation, and maintenance of building fire detection and alarm systems. It is intended that this revised and updated standard will continue to be cited by the Acceptable Solutions and Verification Methods for the New Zealand Building Code (NZBC), be used as a baseline for the development of Alternative Solutions, and also to facilitate approval of evacuation procedures and schemes under the Fire and Emergency New Zealand (Fire Safety, Evacuation Procedures, and Evacuation Schemes) Regulations 2018. This standard does not specify what type of alarm system or alerting device is required for a particular building. Instead, based on declared functional requirements determined by the system owner, it provides an integrated set of rules for the correct design, manufacture, installation, commissioning, documentation, and maintenance of the system. This standard is applicable to fire alarm systems in buildings, except for single station or interconnected smoke alarms for houses which are covered in NZS 4514.
