6.1 Smoke extract ducts
Construction of the duct
EK-JS smoke control dampers are allowed to be used
with sheet steel smoke extract ducts for individual sec-
tions that meet the following criteria:
Tested according to DIN EN 1366-9, 120 min. at 600
°C
Pressure level 3 according to DIN EN 1366-9 for
negative pressure down to -1500 Pa and positive
pressure up to +500 Pa
Smoke extract ducts with national general building
inspectorate licences
Smoke extract ducts can also be connected with a
national general building inspectorate licence or a
national general appraisal certificate. If the smoke
control damper is not exposed to mechanical forces,
the functional stability of the smoke control damper is
not affected (connection according to assembly and
operating manual of the smoke control damper). The
sizing of the smoke extract duct used remains the
responsibility of the system installer and the system
owner and must be approved with the respective
national authority.
