If the PYROLINE
®
Con fire protection duct is used for maintenance of
electrical function, KS-E DE identification plates (item no. 7205423) must
be attached.
If, in the PYROLINE
®
Con fire protection duct, DC cables are routed with
the transformer to connect photovoltaic systems, then the identification
plates KS-BSKP DE (item no. 7214725) must be attached so that the
emergency services can identify the fire protection duct as a photovoltaic
duct.
The identification plates must be
– clearly visible,
– attached beneath the fire protection duct,
– at least in every storey,
– ideally in each construction segment
or room.

If cables are inserted later in the PYROLINE
®
Con BSK fire protection
duct,
– then the proper construction, as described in these instructions, must
be maintained,
– and the approved cable load may not be exceeded (see table).
