The alarm goes off for no obvious reason
■ Look for steam, cooking fumes, etc. which may be coming from the kitchen or
bathroom. Paints and other vapours can also trigger false alarms.
■ Check for any possible contamination from cobwebs or dust. If necessary, clean the
alarm as described in section 5.4.
■ Press the test/silencer button on the smoke alarm to stop the alarm (the red LED
on the alarm flashes quickly) – this will silence the smoke alarm for 10 minutes
(and all other alarms that are interlinked in the system).
■ Smoke alarms with radio modules beep for two seconds every four hours to indicate
that the battery of one device in the system is going flat. Check all alarms as described
in section 5.3.
■ Use house coding for radio alarms – refer to your radio module's operating
instructions. If the alarms are using the default factory settings, they may be
triggered by neighbouring alarms.
The alarm does not emit a warning sound when the test button is pressed
■ Check the age of the alarm – see the “Replacement Date” label on the side of
the device.
■ Ensure that the alarm is fully turned onto the mounting plate, i.e. that the battery is
connected. Note: If the smoke alarm still does not emit a warning sound, it must be
replaced as soon as possible.
