3. Notes upon renovation work

Only mount the smoke detector after completion of all works (reconst-
ruction, renovation etc.).
If smoke detectors were installed before the work is begun with, these
have to be either removed or covered up.
While the work is being carried out, the removed smoke detectors have
to be protected from dust or the like (e.g. store in a plastic bag).

Important:

Following the completion of all work required, the
smoke detectors have to be mounted again or the covers have to
be removed. A smoke detector which is not mounted or which is
still covered cannot fulfil its designated function and is therefore
ineffective.
The use of the smoke detectors in environments with high amounts of
dust and dirt can lead to a reduction in the service life expectancy of the
detectors due to more rapid contamination of the product.
