Smoke and heat removal system
■
In normal operation, 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.
Ventilation system
■
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.
