General information General information
Smoke alarm devices provide early warning
of smoke or fire, so that the residents of the
house and the apartment are able to react on
time, in particular, to leave the premises im-
mediately and to alert the fire brigade. Smoke
alarm devices do not prevent fires, nor do
they fight fires automatically. Smoke alarms
do not directly alert the fire brigade or other
emergency service. Smoke alarm devices are
not used to prevent fire damage, particularly
if no one is present when the fire breaks out.
The smoke alarm devices are subject to strict
quality controls during the manufacture. In
addition, a functional test is performed before
delivery. Nevertheless, unexpected malfunc-
tions may occur.
