NZSA – Building Code and Smoke Detectors


Installing Smoke Detectors in homes?

Changes to the Building Code take place next month that you need to be aware of.

Key points:

  • The adoption of interconnected smoke alarms as the minimum fire safety system in household units. Interconnected smoke alarms work by sending signals between the smoke alarms in a house. These can be wired or wireless.
  • Smoke alarms shall be located in ALL bedrooms, living spaces, hallways, and landings within the building.

Remembering of course – that Smoke alarms shall comply with at least one of the following: UL217 ; CAN/ULC S531 ; BS EN 14604 ; ISO 12239 ; or AS 3786

All wiring between the power supply and the smoke alarms shall be supervised. Power Supply and Backup shall comply with: NZS 4512 or AS/NZS 2201.1

  • Each smoke alarm should be tested at least once per month by activating the ‘test’ function.
  • Each smoke alarm should be inspected and cleaned every 6 months with a soft brush attachment of a vacuum cleaner (without disassembling).
  • A long life (minimum 10 years) non removable, sealed battery
