General information

Smoke alarm devices provide early warn-
ing 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 immediately and to alert the
fire brigade. Smoke alarm devices do not
prevent fires, nor do they fight fires au-
tomatically. Smoke alarms do not directly
alert the fire brigade or other emergency
service. Smoke alarm devices are not used
to prevent fire damage and they cannot
in fact prevent it, especially when no one
is present in case of fire. The smoke alarm
devices are subject to strict quality con-
trols during the manufacture. In addition,
a functional test is performed before de-
livery. Nevertheless, unexpected malfunc-
tions may occur.
