Areas susceptible to draughts
For occurring smoke to be able to reach the
smoke alarm device, there may not be any
strong draughty influences around the instal
-
lation site (e.g. caused by air conditioner and
ventilation intakes, fans). In rooms with forced
ventilation, perforated ceilings that serve for
ventilation must be closed off within a radius
of 0.5 m around the alarm device.
The use of smoke alarm devices is gov-
erned by DIN 14676.

4.1 Area to be monitored
Use a device if at least one of the follow-
ing applies:
•
Monitoring area less than 60 m
2
,
and ceiling height of less than 6 m
•
Ceiling panels (height lower
than 20 cm) with joists (ceiling
surface less than 36 m
2
)

of the following applies:
•
Monitoring area greater than 60 m
2
•
Ceiling height greater than 6 m
•
High partial walls
•
Separating pieces of furniture

)
In rooms with beams (e.g., wooden
beams), the number and arrange-
ment of the devices depends on
the height of the joists and the
surface formed by the beams.
