Safety information

__________________________________________________________________________

2

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 open

ed, 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.

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 national regulations.

230V AC dangerous voltage

Field of application

Maintenance work

Cable routing and electrical connection

Leave the insulation of the power supply

cable in place up to the mains terminal.

Manufacturer's declaration

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).

Where devices are used in smoke and heat

extraction systems, ensure that they are checked,

maintained and, if necessary, repaired a

t 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.

Fuse the 230V AC power supply cable separately on

site.

Adhere to the DIN and VDE regulations (Germany)

or equivalent in your country.

Establish the cable types, if necessary, wi

th 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.

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.

Smoke and heat extraction system alarm trip:

The acoustic signal will only sounds in the break glass unit if the door is closed or if the door contact switch is
pressed.

Break glass unit:
Break the glass in the break glass unit! Press the red button min. 0,5 sec.. 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.

Reopening the actuators

The first 30 min. after a SHE-trig the actuators will be cyclically activated every 2 min in OPEN direction (to
loosen frost fastened windows, domes e.g.).

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.

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. The green operation LED remains lit as a special fault diagnosis.
Operating the ventilation button, OPEN or STOP will lead to the tripping of another alarm.

Note:

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

Option: 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.

If the temperature exceed 73°C the automatically SHE-alarm will be activated.
An acoustic alarm signal in the smoke control unit will start.

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: 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.

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.
