Damper installation
The dampers’ installation is always designated by the
particular ventilation project, which must comply with valid
standards. Damper distances from building constructions,
technological distributors and ventilation devices must be
such that the authorized mounting people will be able to
do the installation, functional tests, revisions and services.
There must be at least 200 mm space between two
dampers or between the damper and the wall or ceiling.
Usage and operation
The DKIR1 / DKIS1 is a part of a heat exhaust ventilation
system (SHEVS). The system helps to keep the exits
smoke-free, facilitates the job for re brigades, slows
down the spread of re. This system is created in larger
buildings, where the size and shape of the building do
not enable natural smoke exhaust when re occurs. The
damper is controlled by a servo-drive which, triggered
by an electric impulse from a smoke alarm or remote-
controlled by electric re signalization center, opens or
closes the damper blade according to the needs of the
SHEVS and according to the situation in relevant re
compartment. Servomotor closes or opens the damper
within 60 seconds.
Transportation, storage
and operation conditions
It is essential to transport the dampers by such means of
transport that provide a cover and secured on pallets. If
manipulation occurs during the transportation or storage,
dampers must be protected against damage and weather
conditions. Damper blades must be in the closed position.
It is recommended to store these products in a closed and
dry area with a temperature range from -10°C to 50°C.
