6. Interpreting signals
6.1.5 Silencing false alarms
Occasionally, smoke alarms can be activated by other triggers, such as dust, insects or
cooking fumes. If you are certain that it is a false alarm, press the large test/silencer
button (e.g. with a broom handle) to silence the alarm for 10 minutes – the red LED will
then flash every 8 seconds for 10 minutes.
6.1.6 Interlinked system sets off the alarm
You can tell which alarm has been set off by the red LED on it, which will be flashing
quickly. In an interlinked system, a remote control can make it easier to localise the
alarm. Once you have localised the device, follow the steps in section 6.1.5.
6.2 Fault indicators
6.2.1 Low battery
The battery will usually last for 10 years before it starts going flat. Check the date
on the side of the device to see when the alarm should be replaced. If the automatic
self-monitoring function identifies that the battery is going flat, the alarm beeps and
the red LED flashes (approx. every 32 seconds) at the same time to warn the user
(the yellow LED flashes on i series models). This indicates that the alarm must
be replaced.
