Smoke control unit - WSC 304 01 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 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.

Smoke control unit - WSC 304 01 9
Cable routing
Observe the safety information on page 2.
For cable routing we recommend the use of fire protected cables retaining their function E90 or E30.
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 centre (except the mains supply cable) carry 24V DC and have to be routed separate
from the mains supply cable.
Adhere to the pertinent VDE regulations when routing the cables.
Do not use the green/yellow conductor.
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.
Control centre installation
Note that the control centre has to be installed in a dry room.
Concealed housing
Refer to the sketch below for the installation position
Open central control and remove the housing
top section (door) from the housing bottom section.
Fasten the housing bottom section in the wall cut-out
(cut-out dimension 335 x 350 x 95) and
refit the housing top section.
Also possibility for surface mounting with the included frames.
Installation of the Break glass unit, ventilation buttons and detectors
Ensure that the Break glass unit and the ventilation buttons are visible and well accessible. Do not fit behind
protruding walls, door panels or hidden by the building structure.
Note: Installation height of the Break glass unit = 1.4 m above floor top edge.
Install the automatic detectors in accordance with the enclosed operating manuals.
Installation
Lead the connection cables into the housing of the control centre from above.
All connection terminals (except the mains terminals) are of the plug-on type.
Connect the connection cables in accordance with the terminal plan. Ensure that the connections are made
correctly.
Incorrect clamping, mixing up numbers or colours could lead to malfunctions of the central control or of the
external components.
Notice:
Smoke central units in metal housing
are only for surface mounting.

Cable lengths table
____________________________________________________________________________
Smoke control unit - WSC 304 01 10
Ensure that the electrical cables are always routed according to the valid national and local regulations of the individual
country.
Maintaining the cable functions
The sample cable system directive (MLAR) in its current version is decisive for the type of cables and their corresponding
way of routing. In most of the German provinces, MLAR has been introduced as Technical Construction Regulation.
Various revisions of the MLAR as Technical Construction Regulation are valid in the individual provinces. Due to the fact
that the requirements with regard to the conductors for smoke control systems contained in the individual versions differ
considerably, different conductor requirements result for the individual provinces. MLAR is based on the state-of-the-art of
the year 2000 (Revision: 06/2001). In this directive, for the first time a differentiation is made between machine operated
and natural smoke ventilation systems. For natural smoke extraction systems it is sufficient to maintain the function
according to classification E30. These cables must be checked and approved in accordance with DIN 4102 Part 12. Route
the cables in conformity with the instructions of the cable manufacturers using the corresponding fastening materials.
The maintenance of the function for the smoke ventilation cables is not required if all cable paths are monitored by the
smoke detector and when the smoke and heat detection system opens as a result of the automatic detector tripping.
Concealed installation is not an approved type of installation to maintain the function in accordance with DIN 4102 Part 12.
The function is also only securely maintained by cables of class E30, or the room is monitored by smoke detectors.
The cable network for smoke ventilation systems („Cable system“) ends at the interface (junction box) for the actuator!
The flexible, heat resistant connection cable of the smoke ventilation system actuator is part of the system component
‚electric motor actuation' and does not belong to the electrical installation!
We recommend in all cases to discuss the type of cable routing with the competent fire fighting authorities.
Independent of the fact whether or not the respective MLAR is introduced in the corresponding province as
Technical Building Regulation, we recommend to point out the technical possibilities and the state-of-the-art of
MLAR 2000.
Cable length table
For determining the maximum permissible cable lengths between the smoke control unit and the actuators, taking into
account the specified cables cross sections, please refer to the following table:
Maximum motor current: 4A (Note: Be aware of the overall capacity of the smoke control unit!)
Maximum cable length: (always routed from the central smoke control unit to the last junction box)
Actuating current: Sum of all motor currents per group module
Note: Do not use the green/yellow wire!
Per motor supply line, 3 wires are required ( 2 wires current carrying /1 wire for monitoring )
Cross section 3 wire 5 wire 3 wire 5 wire 3 wire
1,5 mm² 1,5 mm² 2,5 mm² 2,5 mm² 4 mm²
Actuator current in
Amps (2 wires in
parallel) (2 wires in parallel)
1 84,00 m 168,00 m 140,00 m 280,00 m 224,00 m
2 42,00 m 84,00 m 70,00 m 140,00 m 112,00 m
3 28,00 m 56,00 m 46,67 m 93,33 m 74,67 m
4 21,00 m 42,00 m 35,00 m 70,00 m 56,00 m
(The information is valid for ambient temperatures of 25°C)
Formula for the calculation of the maximum cable length
Permissible max. voltage drop in the line UL : 2 Volt
max. cable length = permissible voltage drop(UL) x conductivity of copper(56) x cable cross section(A)
max. actuator current total (I) in amps x 2
Permissible cable length for the break glass unit supply cable when using......4x2x0.8mm: up to 200m
The motor connection cable length to the junction box (or control module) must not exceed 10 m.
