Smoke Alarm FAQs

  • What’s the difference between Ionisation and Photoelectric smoke alarms?

    Ionisation smoke alarms detect invisible smoke particles created by fast flaming fires. Photoelectric smoke alarms detect slow smouldering fires that create fumes and acrid smoke. It’s recommended that a combination of both Ionisation and Photoelectric smoke alarms should be installed in your home.

  • How often should I replace my smoke alarms?

    It’s recommended that all smoke alarms be replaced 10 years from the date of manufacture. Please check the product label on the back of the alarm.

  • My smoke alarm chirps every 30-40 seconds. Why?

    This is the low battery monitor. Your battery needs replacing.

  • I’ve replaced the battery, however the smoke alarm is still chirping. Why?

    The smoke alarm model Q1275 has a HUSH button on the cover that can be pressed when unintended smoke from cooking activates the alarm. This HUSH feature silences the alarm, temporarily de-sensitises the alarm circuit and chirps every 30-40 seconds for approx. 7 minutes. The alarm automatically resets itself after this time.

    Please note: dense smoke will override the HUSH feature and activate a continuous alarm.

  • My smoke alarm has activated but there is no fire. Why?

    Heat from things such as ovens and toasters can sometimes trigger smoke alarms. 
    If possible, re-locate the alarm away from the heat source.

  • Why didn’t my alarm activate when smoke was present?

    Check the battery and replace if necessary. If the battery is still working, air from an open window or air conditioner may have re-directed the smoke away from the alarm unit.
