Safety information WSC 308 01

Attention!
Adherence to the following information is mandatory:

Only allow correspondingly trained, qualified
and skilled personnel to carry out installation work.

Reliable operation and the avoidance of
damage and hazards is only guaranteed if
installation and settings are carried out carefully
in accordance with these instructions.

Check the technical data on the system plate.
Hazards to persons ensuing from flaps and

wings operated by electric motors.
The forces occurring in the automatic mode can

be such that parts of the body could get crushed.
When opened, actuators could protrude into the
room.
For this reason, measures have to be taken
prior to starting up the actuators which exclude
the danger of injury.

With wings tilting inwards or outwards, the wing
must be protected from hinging down once the
actuator is unhooked (e.g. for window cleaning).
For safety reasons we recommend the use of
catching shears.

In the event that wings or flaps are subjected to
high wind loads, we recommend to connect the
central control unit to a wind detector which will
automatically close the flaps.

The fastening methods are exclusively intended
for the intended use for which they are designed
The manufacturer does not assume any liability
for possible damage resulting from inappropriate
use.

230V AC dangerous voltage

Can cause death, severe injury or considerable
damage to assets.
The connection of the control system is reserved
for qualified personnel.
Disconnect all poles of the unit from the supply
voltage prior to opening, installation or
assembling. Adhere to the VDE regulations.

Field of application

The central control system is exclusively designed
for the automatic closing of smoke extraction
systems, windows, flaps or doors.
Always check that your system meets the valid
regulations.
Pay particular attention to the opening cross section,
the opening time and opening speed. The cable cross
sections depend on the cable length and current
consumption (amperage).

Maintenance work

Where devices are used in smoke and heat
extraction systems, ensure that they are checked,
maintained and, if necessary, repaired at least once
per year.
Remove all soiling from the devices,
check the fastening and clamping screws for firm
seating. Trial run the entire system.
Defective devices may only be repaired in our factory.
Only use original spare parts.
The supplied accumulators are subject to regular
checks and must be replaced every 4 years.

Cable routing and electrical connection

Fuse the 230V AC power supply cable separately on
site. Leave the insulation of the power supply

cable in place up to the mains terminal.

Adhere to the DIN and VDE regulations (Germany)
or equivalent in your country.
Establish the cable types, if necessary, with the local
approval bodies or the fire protection authority.
Do not conceal flexible cables. Junction box
must be accessible for maintenance purposes.
Disconnect all poles of the mains voltage and the
accumulators prior to starting maintenance work or
making changes to the system.
Secure the system to prevent unintentional switching
on again.
Design cable types, lengths and cross sections in
accordance with the technical information.
Route all low voltage cables (24V DC) separate from
the power current cables.

Manufacturer's declaration

The devices have been inspected and manufactured
in accordance with the European directives.
A corresponding manufacturer's declaration is
available.
You are only authorised to use the devices if a
conformity declaration is issued for the entire system.

Technical function description WSC 308 01

Smoke and heat extraction system alarm trip:
Break glass unit::

Break the glass in the break glass unit! Press the red button. The smoke extraction opens.
An acoustic alarm signal sounds (continuous sound) in the break glass unit.
All ventilation functions are out of operation.

Display: The red alarm LED in the smoke control unit and the red LED in the break glass unit are lit.
Smoke detector:

If smoke develops, the smoke extraction system automatically opens.
An acoustic alarm signal sounds (continuous sound) in the break glass unit.
All ventilation functions are out of operation.
Display: The red alarm LED in the smoke control unit, the red LED in the break glass unit, and the red LED at
the tripped automatic detector are lit.

Resetting a tripped smoke control unit:

Press the „CLOSE button“ in the break glass unit or the „Reset button” in the smoke control unit.
The acoustic alarm signal in the break glass unit stops sounding.
The ventilation functions are operational again once the smoke extraction system has closed.
(Prior to resetting, blow out or replace the detector after it was tripped by an automatic detector).
Display: The red alarm LED in the smoke control unit, the red LED in the break glass unit, and the red LED at
the tripped automatic detector extinguish.

Tripping caused by high temperature:

The function is activated, SW 2/1 =ON.
The smoke control system automatically trips if the temperature inside the smoke control unit exceeds 70°C.
An acoustic alarm signal sounds (continuous sound) in the break glass unit.
Display: The red alarm LED in the smoke control unit and the red LED in the break glass unit are lit.
The yellow malfunction LED in the break glass unit flashes. The green operating LED's extinguish.

Resetting a trip caused by high temperature:

The smoke extraction system can be closed again by pressing the „Reset button“ in the smoke control unit or
the „CLOSE button“ in the break glass unit.

After operating the CLOSE function, an acoustic pulse tone sounds, and the flashing malfunction LED is only
displayed in the break glass unit.

Note:

The built-in thermal switch will then be irreversibly destroyed. The smoke control unit has to be returned for
checking.

Alarm trip caused by a malfunction signal:

When this function is activated (SW2/1 = ON), the smoke control unit will trip in the event of a motor, smoke
detector or break glass unit circuit malfunction. An acoustic alarm signal sounds (continuous sound) in the
break glass unit.
No trip occurs as a result of a malfunction in the mains or battery circuit.
Display: The red alarm LED in the smoke control unit 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 unit flash.

Option: External signalling of the alarm or malfunction signal

It is possible to send an alarm or malfunction signal potential free, by plugging in the alarm/malfunction
signalling module.

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.
