Exact damper function is provided under the following conditions:
a) maximum air flow speed 12 m/s
b) maximum vacuum up to 1000 Pa or overpressure up to 500 Pa
The dampers are ONLY suitable for installing in a vertical position, with the blade axis horizontal.
The dampers are designed for environments where they are protected against weather condi-
tions with class 3K5 climatic conditions e.g. without extremes of moisture, temperature, conden-
sation, humidity, ice formation, with a temperature limit of -30°C to 50°C.
In normal operation, the SEDM-L dampers remain closed. If necessary, in the event of a fire, the
SEDM-L dampers in the affected fire section will open completely so that the smoke can be
removed. When the smoke and heat removal dampers are activated, the dampers used for air
supply in the affected section open. The dampers used to supply air in the affected fire section
are installed at the ground. The dampers are controlled from the central control system on the
basis of signals, e.g. from smoke detectors. The use of cables with a certain fire resistance for the
supply voltage ensures that the actuator is supplied even in the event of a fire.
During ventilation, SEDM-L dampers in the smoke and heat extraction system are controlled by
a control system, it's possible to fully open, close or continuously control the flow. The SEDM-L
dampers, which are used for air supply, remain closed during ventilation.
