Testing your smoke, heat, and carbon monoxide alarms ensures that all critical components – including the sensor, internal electronics, and sounder – are functioning correctly. An alarm that isn’t working properly may fail to alert you in an emergency, reducing your ability to escape safely. Regular testing helps identify faults early, so you can take action before safety is compromised.
How often should fire alarms be tested?We recommend testing all smoke, heat, and carbon monoxide alarms once a week. Weekly testing allows you to spot potential issues such as low batteries or fault warnings straight away. Making this a routine habit, perhaps on the same day each week, helps ensure your protection is always active and reliable.
Smoke and heat alarms can be tested using the same simple method:
If you hear the alarm and see the LED flash, you can be confident that everything inside the alarm is working as intended.
If your alarm doesn’t sound during testing, or if it starts beeping when it hasn’t been tested, this is a sign that something isn’t right. The battery may be running low, or the alarm could be approaching the end of its working life. Always refer to the user manual for guidance, but be aware that some issues indicate it’s time for a replacement rather than a repair. If issues persist despite checking the user manual, please contact our Customer Support Team.
This is also a good opportunity to review whether your current alarms still meet your needs. Older alarms may not offer the latest features, such as sealed-for-life batteries or interlinked technology, which can provide enhanced protection throughout your home.
Over time, sensors naturally degrade and become less responsive. On the base of an alarm is typically a replace by date; once this date is reached, the alarm should be changed to maintain effective protection.
