General Information; Connection Possibilities - Window Master WSC 204 Operating Manual/Technical Information

Option: Ventilation time module (time ventilation module WSA 303)
Automatic closing in the ventilation mode according to pre selected time (1 min. to 30 min.) after ventilation
OPEN or STOP was actuated Once this time has elapsed, the actuators close after ventilation „OPEN" or
ventilation „STOP". This function is not operative if the setting potentiometer is on the right-hand stop.
Option: Gab ventilation module (module WSA 304B) WSC 204 / WSC 204KP /
WSC 204MH
It is not always necessary for an electric actuator to open a ventilation unit (window or light dome) by its full
stroke. Sometimes, a small gap is sufficient for ventilation purposes. This module enables time-controlled
limitation of the actuator stroke (the opening time can on the potentiometer be set from 1 - 60 sec). Even re-
triggered in "OPEN" direction the window will not open further than set preset opening value
The module has no influence on the actuator when an "EMERGENCY OPEN" function is triggered. In this case
the actuator opens to its maximum stroke.
It is not possible to install both a WSA 303 and a WSA 304B module in one smoke control panel.
Wind/rain CLOSE
The actuators close when the wind/rain sensor has been activated (potential free contact in the sensor
switches).
As long as the sensor is activated, the ventilation function is out of operation and the green wind/rain LED
lights.
Activated alarm has 1. priority.
Option: Transmission of the wind/rain signal (module WSA 302)
The activated signal of the wind/rain sensor can be transmitted potential free to the next smoke control panel.
1 x change-over contact (max. load: 60V, 1A) with 3 pole connection terminal for potential free transmission
of the wind/rain trip.
CLOSE after a power failure
2 minutes after a power failure actuators opened for natural ventilation will automatically close.
In the event of alarm, this function will be out of operation.
