The smoke detector automatically
checks that it is operating correctly
once a minute. It also automatically
readjusts the sensitivity of its
detection optics to suit its environ-
mental conditions.
The unit gives an early warning if its
energy capacity is low or if the
detection optics have become so full
of imperfections that readjustment is
no longer possible. This gives you
sufficient time to replace the smoke
alarm with a new unit.
Please ensure that the air inlets
located around the edge of the
smoke alarm are never blocked by
dust, dirt, paint of adhesive tape.
You should check that the unit is
functional on a regular basis, at least
once a month, by pressing the test
and stop button (IV) to activate a test
alarm. Check that the unit is free from
damage, that it is held tightly in place
and that the smoke inlet ribs (II) are
completely free from any foreign
