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.

The draft is available for public comment for a period of eight weeks. This sign language translation of DZ 4512 will be distributed through relevant channels accessible to the Deaf community. All comments submitted during this period will be reviewed by the standards development committee before the standard is balloted on.

You can view or download the New Zealand draft standard on the Standards New Zealand website. The closing date for comments is 3 December 2020.
