Whether the point of attachment has been well selected acoustically can tested
by triggering a test alarm (see "Installation") while a genuinely sleeping person
is in the bedroom.
The smoke alarm has to wake the person! It may not just be
audible!
With the following rooms and places, installation of the smoke alarm
can be problematical:
• Kitchen/bathroom: kitchen steam from cooking or the high humidity in the
bathroom can trigger a false alarm.
• Garages: exhaust from the car, motor-bike or other combustion engines
can lead to a false alarm.
• Dusty and dirty rooms: the measuring chamber of the smoke alarm
contaminates very quickly. This makes for a very negative influence on
the measurement of smoke. The smoke alarm could, in case of a genuine
fire, fail to function!
• In the vicinity of windows, ventilators, fans, lamps, luminescent tubes,
halogen transformers, open fireplaces and all other places where the air
moves strongly, the recognition of smoke can be poor or late.
• The close vicinity to steel beams, large metal areas, metal doors etc. can
hinder the radiance or the reception of the radio signal appreciably.
• Tobacco smoke leads to frequent false alarms. The smoke alarm cannot
recognise whether it is just "harmless" cigarette/cigar smoke or a genuine
fire.
There are smoke alarms which possess a sensitivity setting. This
has the disadvantage, however, that in the case of a "genuine"
fire, the alarm is triggered too late which shortens the reaction time
immensely. The time available for extinguishing the fire or saving
persons or flight is much less!
