Description
Smoke exhaustion equipment is used to extract smoke from
the lift shaft and to ventilate it.
They can be installed in the vertical facade or in the roof
area. Only building products with approval as natural smo-
ke and heat exhaust ventilators (NRWG) according to DIN
EN 12101-2 may be used as smoke extraction openings. The
proof of usability under building law is the manufacturer’s
declaration of performance for the respective NRWG or the
abZ / aBG of the
L

system.
The electrically operated
louvre windows
have a frame of
65 mm. They are made of thermally separated aluminium
profiles with insulated inserts of glass or composite panels.
The number of louvres depends on the dimensions of the
louvre window. Customer specific solutions are possible.
The electromotive drives are operated with 24 V DC. Various
mounting frames for standard and special dimensions are
available for retrofitting the louvre windows.
The electrically powered
ventilation and smoke exhaus-
tion hoods
for the roof area are supplied as a ready-to-in-
stall building product. A motorised, thermally insulated
louvre window tested according to DIN EN 12101-2 is in-
tegrated horizontally into the vertical duct of the stainless
steel hood. The nominal sizes or structural openings depend
on the geometric smoke exhaustion area of the installed
louvre window. The electric motor drives are operated with
24 V DC. The hoods are fully resistant to rain and wind even
when the louvre window is open, and their design ensures
that they cannot be broken through.

Smoke exhaustion from the lift shaft via
the roof must be ensured regardless of
the wind direction. NRWG whose declar
ation of performance or product label in-
dicates their use in roof areas with cross-
wind effects are suitable for this purpose.
The electrical performance features of
the drives are given in the technical data
sheets of the respective louvre windows
or on the product labels.

On the
LSF 7000
Control Unit, the
override function is activated as stan-
dard in the event of a RWA emergency
release. After release, the drives are ac-
tuated at regular intervals over a period
of 30 minutes in the CLOSE direction and
then again in the OPEN direction in or-
der to open smoke exhaustion devices
that may have been blocked by the cold.
This function can be deactivated via the
LSF 7000
software.
