Standards NZ Public Comment for Interconnected Residential Smoke Alarms

In BICSI Blog, BICSI Bytes, Featured, News by

Standards NZ recently issued a public comment on interconnected residential smoke alarms. This standard provides a specification for the selection, installation, commissioning, and maintenance of interconnected smoke alarms in houses (single household units).

This edition is a partial technical revision and supersedes NZS 4514:2009. Allowance has been made for long-life batteries and wirelessly interconnected smoke alarms. Changes have been made for ceilings with exposed framing members. Testing requirements have been simplified. The appendices have been edited and updated to provide more clarity and guidance on the selection and location of smoke alarms.

The public comment period closes on Wednesday 7 October 2020.
