Control Panel WSC 204MH

Compact smoke control panel for control of ±24V DC window actuators with a total power consumption up to max. 4.8A for smoke extraction and daily comfort ventilation.

The smoke control panel is especially suitable for surveillance of smaller areas, e.g. staircases, smaller sport centres and restaurants.

By linking several smoke control panels in a master/slave system, the smoke control unit can also be used in larger buildings.


The smoke control panel opens the window actuators during smoke.
The panel is supplied in steel housing and is suitable for surface mounting.
