DZ 4512:2020 (Committee P4512/4514)
Fire detection and alarm systems in buildings
This standard provides a complete specification for the design, manufacture, installation, documentation, and maintenance of building fire detection and alarm systems, whether operated manually or automatically, in the event of fire. This edition is a full technical revision which, when finalised, will supersede NZS 4512:2010. The key areas that this revision has addressed are as follows: • Significantly expanded specifications and guidance for the design and use of visual alerting devices in anticipation of their increased use for alerting the deaf and hard of hearing. • Specific provisions for wireless-based detection and alarm technology, networked systems, and smoke detectors in ducts. • New requirements for power supplies to support the full alarm load, earth fault monitoring, and seismic performance. • New design requirements for the normal indicator, a standard cabinet key, enhanced EMC immunity, and labelling. • Acceptance of equipment complying with new overseas standards, including short-circuit isolators and input/output devices. • Changes to installation practice: increased zone sizes, reduced allowance for detector substitution, increased manual call point spacings, increased fault resistance in large alerting systems, and crimp-pin termination and identification of cables. • Clarification of cable diversity requirements, manual call point locations, requirements for line-type heat and beam-type smoke detectors, requirements for maintenance access, and Type 5 alerting and hush facilities. • Additional requirements for commissioning and routine testing, including an expanded escalation and resolution process for unresolved system impairments. • Significantly expanded requirements for system documentation, commissioning, inspection, and certification. • Numerous other changes and enhancements. This draft is available for public comment for a period of 8 weeks. All comments submitted during this period are reviewed by the standards development committee before the final standard is balloted on.
