Smoke alarms must be installed to ensure smoke can easily enter the alarm in the event of a fire, hence by avoiding dead air spaces.
Also keep away from areas that may lead to false alarms, such as areas prone to dust, insects or humidity/steam (i.e. bathroom).
Aim to also keep 1m away from A/C ducts and electrical noise sources such as LED lighting.
Home Insurance and Smoke Alarms
Smoke alarms play an integral role in home security and are a legal requirement right across Australia. That’s why insurance providers have made smoke alarms a prerequisite for obtaining home insurance. By not having the appropriate protection as determined by state government, an insurance provider may increase the price of premiums or choose to reject an insurance claim altogether.
