POSITIONING
Thermoptek smoke alarms are less prone
to false alarms from cooking fumes, and
are therefore suitable for locations near
kitchens. However like other types of
smoke alarms, thermoptek smoke alarms
can be susceptible to nuisance alarms from
steam and should not be located too close
to bathrooms and showers.
It is recommended that your FireAngel
smoke alarm is NOT to be tted in the
following locations:
• Bathrooms,shower-rooms,andothervery
damporhumidareas,wherethemoisture
cancauseunwantedalarms.
