Installation and commissioning
Installation is carried out according to
the installation and operating manual.
Mortar-based installation:
– In solid walls and ceiling slabs
– In lightweight partition walls with metal support
structure and cladding on both sides
– In timber stud walls and half-timbered
constructions with cladding on both sides
– In fire walls with metal support structure
and cladding on both sides
– In shaft walls with or without metal support
structure and with cladding on one side
– On wooden beam ceilings
– On modular ceilings (Cadolto system)
Dry mortarless installation:
– In lightweight partition walls with metal support
structure or steel support structure and
cladding on both sides: with installation kit TQ
– In timber stud walls and half-timbered
constructions with cladding on both sides
and installation kit TQ
– In fire walls with metal support structure and
cladding on both sides with installation kit TQ
Standards and guidelines
– Construction Products Regulation
– EN 15650:2010 Ventilation for buildings –
Fire dampers
– EN 1366-2:2015 Fire resistance tests

Maintenance
– The functional reliability of the fire damper
must be tested at least every six months;
this has to be arranged by the owner of the
ventilation system; functional tests must be
carried out in compliance with the basic
maintenance principles stated in EN 13306
and DIN 31051. If two consecutive tests,
one 6 months after the other, are successful,
the next test can be conducted one year later
– A functional test involves closing the damper
blade and opening it again; with a spring return
actuator this can be done via remote control
– Fire dampers must be included in the regular
cleaning schedule of the ventilation system.
– For details on functional tests, maintenance
and inspection refer to the installation
and operating manual
