    • An alarm must be installed in each storey of the building. On storeys with bedrooms, the alarm is to be located between the bedroom and the remainder of the building.
    • Smoke alarms may be hard wired or battery operated.
  1. If your home was built before 1 July 1997 and you don’t already have smoke alarms installed, you now need to install a photoelectric smoke alarm – this can be 240 volt hard wired by an electrician OR a 10 year sealed lithium battery type.
  2. If your home was built or has undergone major renovations after 1 July 1997, it should already have 240 volt (hard wired) smoke alarms installed.
  3. From 1 May 2014, for new and renovated buildings, smoke alarms must be interconnected where there is more than one alarm.
  4. Smoke alarms must be installed in a Class 1a building on or near the ceiling in
    • any storey containing bedrooms
      • between each part of the dwelling containing bedrooms and the remainder of the dwelling; and
      • where bedrooms are served by a hallway, in that hallway; and
    • any other storey not containing bedrooms
  5. In a Class 1 b building, smoke alarms must be installed on or near the ceiling –

  1. Rental Properties:
    • From 1 May 2016 ALL smoke alarms in rental properties are required by law to be either mains powered or have a 10 year non-removable battery.
  1. Do not place Smoke Alarms in any of the following areas:
    • Places where the normal temperature can exceed 45oC or be below 5oC (e.g. attics; furnace rooms, directly above ovens or kettles etc.) as the heat & steam could cause nuisance alarms.
    • Near a decorative object, door, light fitting, window moulding etc., that may prevent smoke or heat from entering the Alarm.
    • Surfaces that are normally warmer or colder than the rest of the room (e.g. attic hatches). Temperature differences might stop smoke or heat from reaching the unit.
    • Next to or directly above heaters or air conditioning vents, windows, wall vents etc. that can change the direction of airflow.
    • ln very high or awkward areas (e.g. over stairwells) where it may be difficult to reach the alarm (for testing, hushing or battery replacement).
  2. Best Practice
    • Locate the unit at least 1m from dimmer controlled lights and wiring as some dimmers can cause interference.
    • Locate unit at least 1.5m and route wiring at least 1m away from fluorescent light fittings as electrical “noise” and/or flickering may affect the signals of interconnected models.
