Special case: SD with deactivated environmental monitoring
If in extremely rare cases
(e.g. in extremely cramped
hallways) the environmen-
tal monitoring function of
the radio frequency smoke
detector had to be deactiva-
ted completely by Techem
during installation, this will
be stated clearly on a sticker
(“Jährliche Sichtprüfung” =
“Yearly visual inspection”)
on the user key.
!
In that case, the mandatory yearly check must be carried out
manually – as described on pages 24 and 25.
What should I do when renovating?
!
You may neither mask the smoke detector nor cover it. Moreover,
you may neither paint over the SD nor subject it to soiling due to
work which gives off large quantities of dust.
