Ventilation Functions - Window Master WSC 204 Operating Manual/Technical Information

Display:
The red alarm LED in the smoke control panel and the red LED in the break glass unit are lit.
The yellow malfunction LED in the break glass unit and the corresponding yellow malfunction LED in the
smoke control panel flash. The green operating LED stops lighting.
Option: Accumulative signalling of the alarm or malfunction signal (module WSA 301)
It is possible to send an alarm or malfunction signal potential free, by plugging in the alarm/malfunction
signalling module.
The sending of the alarm can be stopped. If this is done, the yellow LED on the module will lit.
Multi malfunction warning
1 x change-over contact (max. load: 60V, 1A) with 3 pole connection terminal for potential free transmission
to the BMS / panel etc.
2 pole connection terminal for 2 wire BUS cable for the feedback of malfunctions in cascaded control units to
the break glass unit connected to the master smoke control panel.
Alarm message
1 x change-over contact (max. load: 60V, 1A) with 3 pole connection terminal for potential free transmission
to BMS / panel etc., or as monitored 2 wire alarm cable for cascading control panels.
Jumper plugged in J1 = Only for the alarm transmission to the next smoke control panel (cascading).
Jumper plugged in J2 = pot.-free alarm contact (factory setting).
The transmitting can be interrupt. If so, it will be shown by the yellow LED.
Option: Cascading smoke control panels (module WSA 301)
The smoke control panels can be cascaded by a monitored 2 wire connection from the alarm module of the
master smoke control panel to the smoke detector input of the slave central panel.
A malfunction in the cascaded smoke control panels is detected via the 2 wire BUS cable. The malfunction is
only displayed in the corresponding smoke control panel and in the break glass unit connected to the master
smoke control panel (primary break glass unit type WSK 320).
Option: ASV connection (module WSA 306)
The smoke detector input can be used for receiving a signal from an external fire detecting system (ASV). This
requires a potential-free ASV contact and the ASV module WSA 306.
WSC 204 / WSC 204KP / WSC 204MH: ABA OPEN
To generate a trip (EMERGENCY OPEN) of the smoke ventilation group actuate the potential-free contact in
the ASV. All smoke ventilation actuators "OPEN" automatically. An acoustic signal will sounds in the primary
break glass unit (if mounted). The ventilation function/buttons are now out of operation.
WSC 204BZ: ABA CLOSE
To generate a trip (EMERGENCY CLOSE) of the smoke ventilation group actuate the potential-free contact in
the ASV. All smoke ventilation actuators "CLOSE" automatically. An acoustic signal will sounds in the primary
break glass unit (if mounted). The ventilation function/buttons are now out of operation.
The break glass unit has higher priority than ASV.

4.2. Ventilation functions

Ventilation OPEN
If the momentary function is activated (SW2/2 = ON), the actuators only move open for as long as the OPEN
button of the ventilation button is kept pressed. (CLOSE still has self hold.)
If the latching function is activated (SW2/2 = OFF), the actuators open after pressing the OPEN button.
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).
