1 Safety information
1.1 Safety
Only allow correspondingly trained, qualified and skilled personnel to carry out installation work.
Reliable operation and the avoidance of damage and hazards are only guaranteed if installation and settings are carried out
carefully in accordance with these instructions.
There may be personal danger by electrically operated windows:
- the forces occurring in the automatic mode can be such that parts of the body could get crushed
- when opened, actuators (spindles) 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.
For safety reasons we recommend to install opening restrictors on bottom-hung windows.
In the event that windows are subjected to rain and/or high wind loads, we recommend connecting a wind/rain sensor to the
smoke ventilation panel for the automatically closing of the windows.
The smoke ventilation panel is to be located in a safe place, protected from the effects of fire and smoke.
The smoke ventilation panel is to be surface mounted.
The smoke ventilation panel has two energy suppliers: 230V AC and back-up batteries.
The manufacturer does not assume any liability for possible damage resulting from inappropriate use.
1.2 230V AC
230V AC can cause death, severe injury or considerable damage to assets.
The connection of the smoke ventilation panel is reserved for qualified personnel.
Disconnect all poles of the panel from the supply voltage prior to opening, installation or assembling.
Installation and use according to the national regulations.
1.3 Back-up batteries
Back-up batteries 2 batteries per panel can cause severe injury or considerable damage to assets.
The connection of the smoke ventilation panel is reserved for qualified personnel.
Disconnect all poles of the panel from the back-up batteries prior to installation or assembling.
Ensure that the mains cable can be switched via an external or customer-supplied two-pole switch element or a switch element
controlling all poles –see section 7.1 “Cable routing”
Installation and use according to the National regulations.
Dispose of used batteries according to the National regulation.
CAUTION
RISK OF EXPLOSION IF BATTERIES ARE REPLACED BY AN INCORRECT TYPE.
1.4 Application
The smoke ventilation panel is exclusively designed for the automatic opening and closing of smoke extraction systems,
windows, flaps or doors.
Always check that your system meets the valid national 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).
1.5 Cable routing and electrical connection
Fuse the 230V AC power supply cable separately on site.
Cable routing and connection - adhere to national regulations.
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 back-up batteries prior to starting maintenance work or making changes to the
system.
Secure the system to prevent unintentional switching on again.
Route all low voltage cables (24V DC) separate from the power current cables.
Design cable types, lengths and cross sections in accordance with the technical information.
Cable specifications is a guide only, the overall responsibility resides with the electrical contractor on site.
Installation must be in accordance with the national electrical regulations.

2 Structure of the smoke panel
Sizes & Versions
The WSC 310 and WSC 320 smoke ventilation panels are available in two different versions namely a Standard and a Plus
version. This installation instruction only deals with the Standard versions. Please see separate installation instruction for the
Plus versions of WSC 310 and WSC 320.
Cards
Each panel contains a power supply unit (SMPS), either a WCA 3P1 or a WCA 3P2 for the 10A or 20A version respectively.
Aside from the power supply unit the Standard version also includes a main control card type WCA 3SS.
If additional motor lines, inputs or fieldbus connection is required a Plus version of the panel is necessary.
The Main control card type WCA 3SS allows connections of 2 motor lines and 2 keypads.
Motor groups and motor lines
A motor group consists of one or more motor lines and all the motor lines are operated simultaneously.
Both motor lines on the main control card (WCA 3SS) can be configured for either a ±24V standard actuators or MotorLink®
actuators. A motor group can contain motor lines with both ±24V standard actuators and MotorLink®actuators, whereas a motor
line only can have ±24V standard or MotorLink®actuators connected.
Break glass unit
Break glass unit type WSK 50x are to be used together with WSC 310/320. The number of smoke zones is determined by the
number of inputs to which break glass units are connected. On the Standard version max 2 smoke zones are possible.
Inputs
Cabling
The WSC 3xx CompactSmoke™ uses bus
technology and the overall cabling for break
glass units, smoke detectors and keypads is
significantly reduced compared to other types of
smoke panels.
The main control card has 1 input for a smoke
detector, 2 inputs for break glass units (where
up to 10 break glass units can be connected)
and 2 inputs for ventilation keypads (no max
number of keypads).
Smoke detectors are either connected to the
smoke detector input or to a break glass unit
(type WSK 501 / 502).
The panel can have up to 2 smoke zones and 2
motor groups.

5
System example with
WSC 320
Smoke ventilation panel (20A) with 2 smoke
zones.
The keypads and smoke detectors are cabled
directly to the break glass units in the smoke
zones, which means that the need for cabling in
the building is significantly reduced.
A wind/rain sensor is connected to close the
windows during comfort ventilation in case of
high wind and/or rain.
The smoke ventilation panel is connected to the
Fire Alarm System via the WCA 3SS card.

The standard version of the panels have 16 DIP switches for easy configuration of the panel, see section 11 for further
information.
3.1 Max numbers of actuators per motor line and panel
The table shows the maximum number of actuators, which can be connected per motor line and panel depending on the type of the
actuators, panel and connected cards. The total power consumption of all the connected actuators must not exceed 10A or 20A
depending on panel size.
WSC 320 with 20A includes up to two motor lines each with 10A. If there is a need of more than 10A on one motor line, DIP switch
2.6 is set to 20A. Hereafter one motor line can be loaded with 20A or two motor lines can loaded up to a total of 20A e.g. 17A and
3A.

smoke.
7 Installation
7.1 Cable routing
For cable routing we recommend the use of fire protected cables retaining their function E90 or E30.
See also chapter 8 “Cable dimensioning” in this instruction.
However, this has to be agreed with the Engineer or, if necessary, with the local fire protection department.
Do not reduce the cable cross sections specified in the cable lengths table.
All cables of the control (except the mains supply cable) carry 24V DC and have to be routed separate from the mains supply
cable.
Adhere to the pertinent national and local regulations when routing the cables.
Lead the connection cables into the housing of the control panel from above
and the cable glans shall comply with fire class V-1 (IEC/EN 60695-11-20 / UL
94) or higher and be in accordance with national and local regulations.
Ensure that the mains cable can be switched via an external or customer-supplied
two-pole switch element or a switch element controlling all poles –see drawing.
7.2 Cables into housing
All connection terminals (except the mains terminals) are of the plug-in type.
Connect the connection cables in accordance with the terminal plan. Ensure that the connections are made correctly.
Incorrect cable clamping, mixing up numbers or colours could lead to malfunctions of the control panel or of the external
components.
Ensure that the electrical cables are always routed according to the valid national and local regulations.
7.3 Connection of safety earth wire and 230V AC
See chapter 10 ‘Description of cards’, section 10.1 for further description.
7.4 Installation of the break glass unit, ventilation keypad and smoke detector
Ensure that the break glass unit and the ventilation buttons are visible and well accessible. Do not install behind protruding
walls, door panels or hidden by the building structure.
Note: Installation height of the break glass unit 1.5 –1.7m above floor.
Install the smoke detectors in accordance with their enclosed instructions

10
7.5 Assembly instructions
Always have assembly, installation, repair and maintenance of smoke and heat extraction systems carried out by
qualified personnel trained for this purpose.
Rules to be adhered to for setting up and installation
The following safety relevant rules have to be adhered to when planning the use of a smoke and heat extraction system and its
set-up and installation:
•The Provincial Building Ordinance of the provinces,
•The regulations of the competent fire protection authority,
Accident prevention regulations
Adhere to the general accident prevention regulations (APR), the APR for power operated windows and doors, and the
installation rules in your country.
CAUTION:
Live components are directly accessible after opening the system housing.
Prior to inserting / removing cards disconnect to the panel from the mains supply and the back-up batteries.
•adhere to the installation instructions and your local energy providers
•select the place of installation such that free access is guaranteed for maintenance purposes
•select cables according to regulations in this instruction - take the calculation of the actuator supply cable lengths
into account when laying the cables
•power cables entered via the cable glands
•connect the cables in accordance with the drawings provided by the manufacturer
•route the cables in the building according to the regulations in this instruction
•after the smoke panel is installed the back-up batteries will be fully charged after ca. 8 hours
•check all system functions
Electric cable routing for smoke and heat extraction systems
Electrical cables always have to be laid in accordance with the national and local rules in your country.
Do not use the PE wire / green/yellow wire!
Cables of type NYM, concealed, can be used.
For surface laying, halogen free safety cables are recommended (see cable plan).
If possible, the use of cable types should be agreed with the Technical Services and the competent fire protection authority.
For the maximum permissible cable lengths of the actuator supply cables for the WSC 3xx system, taking the specified cable
cross sections into account (cable information for surface laying), please refer to chapter 8 “Cable dimensioning”.
8 Cable dimensioning
8.1 Maintaining the cable functions
According to valid national regulations.
The cable network for smoke ventilation systems (“Cable system“) ends normally at the interface (junction box) for the actuator!
The flexible, heat resistant connection cable of actuator is part of the system component‚ electric actuator actuation, and is not a
part of the electrical installation!
We recommend in all cases to discuss the type of cable routing with the competent fire fighting authorities.
8.2 Max. cable Length
Maximum permissible cable length from the smoke ventilation panel to the actuators and pyrotechnic gas generator taking into
account the cable cross-section is shown in the following tables for “± 24V standard actuators“, “MotorLink®actuators“ and
pyrotechnic gas generator.
8.2.1 Formula for the calculation of the maximum actuator cable length
Max. cable length = permissible voltage drop 2V (UL) x conductivity of copper(56) x cable cross section in mm2(a)
max. actuator current total in amps (I) x 2
For both ±24V standard actuators and actuators with MotorLink®the cross section of the cable must not be less than 0.75mm2
regardless of the result of above formula.
Maximum actuator cable length: Always measured from the smoke to the last junction box
Permissible max. voltage drop in the line: 2 Volt
Actuating current: Sum of all actuator power consumption per motor line
Note: do not use the PE wire / green/yellow wire!
Example
Max actuator cable length with cable cross section 0.75mm2and actuator current 2A: (2 x 56x0.75) : (2 x 2) = 21m

11
8.2.2 Max cable length –±24V standard actuators
The actuator supply cable must have 3 wires: 2 wires current carrying / 1 wire for monitoring.

The number of actuators per motor line depends on the actuator type, the total power consumption of actuators
connected to a motor line can max be 10A and the total max power consumption for both motor lines must not
exceed 10A or 20A depending on panel type.
Besides actuators also locking actuators (espagnolettes actuators) type WMB 801/802 and WMB 811/812 can
be connected. The power consumption of the locking actuators are not to be included in the 10A / 20A as
actuators and locking actuators do not run at the same time.

15
All actuators on the same motor line will run/be operated simultaneously.
All actuators on the same motor line must be of the same type.
Connection / cable diameter: flexible max 6 mm² / solid max 10 mm².

Up to 5 break glass units type WSK 503 or WSK 504 can be connected to each line. If keypad and smoke
detector are to be connected to the break glass unit, WSK 501 or WSK 502 are to be used. Max one of these
break glass unit on each motor line, the remaining units (up to four) must be of type WSC 503 or WSC 504.
As the break glass units are monitored,
the connection of the break glass units
depends therefore of the number of
smoke zones.
Break glass unit must not be connected
in a ring bus.
Keypads and smoke detectors can also
be connected on the break glass unit
type WSK 501 / 502.
Per panel up to 10 break glass units can
be connected.
But only 2 of these 10 (one per line) can
be a type WSK 501 / 502 to which
keypads or smoke detectors can be
connected. The remaining break glass
units must be type WSK 503 / 504.
