InterLINKED smoke alarms for houses

The Building System Performance branch of MBIE has sponsored access to view and print a single downloadable PDF copy of this standard at no charge. Standards New Zealand also offers this standard to be purchased as Hard Copy or Online Library subscription.

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.

Interlinked Smoke alarms

  • One smoke alarm installed in the room most frequently used for general daytime living purposes – this may be your living room.

OUR Intelligent Wireless Interlink Technology allows multiple units to be wirelessly interlinked to protect the whole household. When one alarm activates, the entire network activates. These alarms are the future of smoke and fire detection. In larger residences, they provide peace of mind knowing that a small fire emerging away from where people are sleeping will still provide an immediate close proximity warning allowing action to be taken before the fire gets out of control.
