Smoke alarms are only guaranteed to work if they are serviced in accordance with the Australian Standard. This involves cleaning the smoke alarm (6-monthly) and replacing the battery (annually). We remove or detach the smoke alarm from its base, wipe down the entire alarm with cleaning wipes, then install a new battery. The alarm is then re-attached to its mounting base and tested with smoke to ensure it’s ready for use. Should the alarm fail the smoke test, we will supply a quote for its replacement.
