A Test Button Is Important, but It Is Not the Whole Check

Householders should test and clean smoke alarms regularly in line with current Queensland Fire Department and manufacturer guidance. A monthly test helps confirm the alarm can sound; gentle cleaning helps prevent dust and insects from affecting the sensing chamber. Never disable an alarm or remove a battery simply because it has activated unexpectedly.

A professional service goes further. We check the condition and age of the alarms, confirm the required locations remain covered and test whether every interconnected unit activates as intended. This is especially useful where alarms are hard to reach, the system contains several models or a property has changed since the alarms were installed.

Yes. Smoke alarms have a limited service life and Queensland requirements specify that compliant alarms must be less than 10 years old. Replace-by information is generally printed on the alarm or identified from its manufacture date and instructions.
