Legislation is pushing us toward interconnected photoelectric smoke alarms. You might now wonder, what are interconnected photoelectric smoke alarms? Let’s break that down and have a look at each element of them. 


Interconnected smoke alarms talk to each other. When one alarm detects smoke, it alerts the others. Which in turn alert you sleeping peacefully in your bed while a fire smoulders in another part of your home.

Don't be a fool. Change your smoke alarm battery annually.

The don’t be a fool campaign was launched back in 2012. Since then, April 1st has become associated as the day to swap out your old smoke alarm batteries. It’s an easy day to remember. If you didn’t swap your battery this April Fool’s Day, do it now.  

Your smoke alarm should be replaced if it is 10 years or older.

Wouldn’t that be wonderful?

These features aren’t all singular to Google Nest smoke alarms. If you checked out the caravan smoke alarm article, for instance, you’ll have seen that their detectors have a hush button. This button allows you to press it before you smoke up the house with the cooking, momentarily preventing the alarm going off. 

Modern smoke alarms have many features not dreamt of years ago and provide many reasons to upgrade. 

Reason Five: House fires

House fires in Australia are the largest cause of property loss, causing an estimated  $9.8 million in damage each year. Most of these fires begin in the kitchen.

To prevent electrical fires make sure your smoke alarms are in working order. There are a number of other ways to ensure your property is safe from potential electrical fires they include: 

  • Don’t overload powerpoints and powerboards
  • Regularly check electrical leads for damage
  • Never use faulty electrical leads or appliances
  • Roll your electric blanket – don’t fold
  • Where possible turn off all electrical appliances at the powerpoint
  • Turn off heaters when not at home and before going to bed. 
  • Provide adequate ventilation around all electrical equipment to avoid excessive heat build up.


The final major cause of house fires are cigarettes and candles.

  • Keep candles well away from curtains and always put candles out when you leave the room
  • Extinguish cigarettes properly before disposal
