3. Warnings

Only mount the smoke detector after completion of all works (re-
construction, renovation etc.).
If smoke detectors were installed before the work is begun with,
EN
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.
