Smoke control unit
– Type: WSC 308 01
5
Technical function description WSC 308 01
Ventilation functions:
Ventilation OPEN:
With the dead man's circuit activated (SW2/2 = ON), the actuators only move open for as long as the OPEN
button of the ventilation button is kept pressed.
If no dead man's function is activated (SW2/2 = OFF), the actuators open after pressing the OPEN button
(self hold).
Display:
The ventilation open LED in the ventilation button is lit (only with LED integrated in the button).
Ventilation stop:
The actuators stop when both buttons are pressed.
Display:
The ventilation open LED in the ventilation button remains lit (only with LED integrated in the button).
Ventilation closed:
The actuators close after pressing the CLOSED button.
Display:
The ventilation open LED in the ventilation button has extinguished (only with LED integrated in the
button).
Option: Ventilation time module
Time setting between 1 and 30 min. Once this time has elapsed, the actuators clo
se after ventilation „OPEN“
or ventilation „STOP“. This function is not operative if the setting potentiometer is on the right-hand stop.
Wind/rain CLOSE:
The actuators close when the wind/rain sensor has tripped (potential free contact in the sensor switches). The
ventilation functions are out of operation as long as a tripped situation is pending.
Option: Transmission of the wind/rain signal
The trip signal of the wind/rain sensor can be transmitted potential free to the next smoke control unit
by plugging in the wind/rain relaying module.
Note: All ventilation functions are locked in the event of a power failure or when an alarm is triggered!
General information:
CLOSE after a power failure:
Opened actuators will automatically close via the ventilation system 2 minutes after a power failure.
The motor voltage will be deactivated after another 2 minutes.
In the event the smoke control system trips, this function will be deactivated.
EMC protection:
All inputs and outputs are protected from coupled in interferences.
Short-circuit protection:
All outputs are protected against short-circuit and overload.
Maintenance:
Smoke control systems must be maintained by the builder at least once per year.
The maintenance and check of the system must be documented in a test placard in the smoke control unit as
well as in a logbook.
