Description
be attached to the ceiling in the
middle of the room, at a mini-
mum distance to walls, beams
and furniture of 50 cm (20 in-
ches). In L-shaped rooms the
smoke detector should be
installed on the mitred lines.
In large L-shaped rooms each
section is regarded as a
separate room.
In areas with sloping and
peaked roofs, the smoke alarm
must be mounted 90 cm from
the highest peak, since air does
not move in the slope/point.
This results in the smoke being
detected too late.
