Interconnected smoke alarms for houses
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.
