– 2 WSC 540, 4 motor groups in 3 smoke
zones, Master-Slave and Controlling/Controlled
smoke zone configuration
5.1 Description
In a building with a large atrium, all the atrium roof windows must open in case of fire. The façade windows
must open only in the part of the building, which is on fire.
Due to cable length limitation, half of the atrium windows are connected to one smoke panel (WSC1), which
is located in one part of the building. The other half of the windows are connected to another smoke panel
(WSC2), which is located in the other side of the building.
We are using two pcs. WSC 540 0SS0 0SS0 E3 to implement the required system.
Since the windows in the atrium are connected to two different smoke panels, the smoke zones with the
atrium windows will be implemented as a Master-Slave configuration, enabling the possibility of creating a
smoke area.
The two smoke zones, controlling the façade windows in each part of the building, will both be configured as
controlling zones of the atrium smoke zones. When activated the façade smoke zone, can then trigger the
atrium smoke zones.
