Cascading smoke control units:
The smoke control units can be cascaded by a monitored 2 wire connection from the alarm module of the
master smoke control unit to the smoke detector input of the slave central panel.
A malfunction in the cascaded smoke control units is detected via the 2 wire BUS cable. The malfunction is
only displayed in the corresponding smoke control unit and in the break glass unit connected to the master
smoke control unit.:
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
Timemodule WSA 303:
Time to be set
between 1 and 30 min. 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.
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.
The tripped signal is shown with the green wind/rain LED.
Alarm tripping has 1. priority.
Option: Transmission of the wind/rain signal
Module WSA 302:
The trip signal of the wind/rain sensor can be transmitted potential free to the next smoke control unit.
CLOSE after a power failure:
2 minutes after a power failure actuators opened for natural ventilation will automatically.
In the event of alarm, this function will be out of operation.
General information:
EMC protection:
All inputs and outputs are protected from coupled in interferences.
Short-circuit protection:
All outputs are protected against short-circuit and overload.
