Flexible connector must be normal flammability and in case of fire
the grounding bonding should disconnet to guarantee the com-
plete separation between fire damper and connected air duct.
When flexible connectors made of conductive material (e.g. alumi-
num) are used, no additional grounding bonding is required.
Despite flexible connector installation, the fire damper must be in-
stalled in the construction support so that its weight does not affect
damper's installation position both during normal operation and in
case of fire.
It is recommended not to compress flexible connectors in the in-
stallation phase.
Flexible connector must be at least 100mm long and in order that
possible duct thermal expansions are balanced.
Take care that the flexible connector does not interfer with opening
/ closing movement of the blade.
Transfer Application (application not connected to air ducts on
„
one or both sides)
Following tests performed as per EN 1366-2, section 6.3.6 Standard,
it is possible to install the fire damper free from air duct from one or
both sides.
• Attention: fire resistance classification for transfer application is
conform to section Fire resistance classification according to EN
13501-3-2009 limited to EI 120S if the ducted classification is high-
er.
• End cap with mesh shall be mounted on the side not connected
to air duct.
• End cap with mesh is made from galvanized steel sheet and in-
cludes nuts and screws for fixing on fire damper.
• End cap with mesh is supplied loose from the fire damper.
