Smoke Detector Requirements in Rental Property


Every year people die as a result of fires in the home. The majority of the fires occur at night when people are asleep. Most fires are preventable. Take precautions to protect yourself, your family and your home. 


Electricians Plus can design, supply and install the correct type of smoke detector for your home.


How to choose between brands and types 

There is no general-purpose smoke alarm for all locations. The correct choice is important to avoid false alarms, as excessive false alarms can lead to the householder disabling the smoke alarm.


There are two choices of smoke alarms:


240 Volt Smoke Alarms (Also called hard-wired smoke alarms)

A 240 volt smoke alarm is connected to a homeís electrical system and has battery back-up power supply.



  • Considered more reliable in the longer term
  • Early warning - occupants alerted in the shortest possible time
  • Uses a battery to provide back-up power if the AC power fails
  • Models can be interconnected which sound alarms in all connected units
  • Can come with a long life Lithium Battery - built-in and tamper proof
  • Power-on indicator
  • In some models a hush button - to stop nuisance alarms
  • Test button - to ensure correct operation
  • Tested by Scientific Services Laboratories to comply with AS3786
  • Some can be purchased with a rechargeable battery (non-replaceable)


  • More expensive
  • Need to be installed by a qualified electrician

9 Volt Smoke Alarms (Also called battery operated smoke alarms)

A 9 volt smoke alarm is stand alone and operated only by a battery.


  • Easy to install
  • Test button - to ensure correct operation
  • Low battery indication
  • In some models a hush button - to stop nuisance alarms
  • Battery missing indicator
  • Tested by Scientific Services Laboratories to comply with AS3786
  • Some models can be interconnected


  • Battery needs to be replaced regularly

Smoke alarms can be installed either stand alone or interconnected. Interconnection allows all smoke alarms to sound simultaneously should any one alarm activate. All occupants are alerted, maximizing the opportunity for escape. Childrenís bedrooms should have a smoke alarm, and be connected to the parentís bedroom because children sleep much sounder than adults. A significant percentage of residences fitted with smoke alarms remain unprotected due to depleted or missing batteries. So test them regularly!
