Drive positioning: Asymmetrical
Asymmetrical linkage of casement bracket or frame bracket can be
used in case of lack of space on the window frame / casement.
Drive positioning: Symmetrical
Symmetrical linkage of casement bracket or frame bracket
should always be preferred to an asymmetrical one.
Advantage:
• for a Tandem-drive application, combination of drives
in R / L version can be used
• uniform force transmission to the window
• uniform casement pressure (tightness)

Area of Application / Range of Application
These chain drives are used for electromotive opening and
closing of windows in facades and roofs, with a mounting
height (lower edge of moving element) of at least 2.5 me-
ters from the
fl oor, for natural smoke and heat exhaust
(NSHEV/ SHEV) and for natural ventilation.
The main purpose of this product is to help save life
in the event of a fi re and to ensure the supply of fresh
air in the building.
The safety features of this product are crucial for compli-
ance with the Machinery Directive 2006/42/EC as well as
standards EN 12101-2.
The most important requirement is that the window opens
after:
• activation via a control unit (SHEV unit)
- from a fi re alarm button
- from a smoke detector or
- from the fi re alarm system (FAS).
Casement type:
roof window / skylight dome / bottom-hung casement, top-
hung casement, side-hung casement / parallel opening ca-
sement.
Made of base materials such as aluminum, plastic or wood.
Opening direction:
inward and outward opening
All specifi ed casement sizes shall be a guide only.
The actual application area depends on the ratio between:
FAB/FAH, total casement weight and opening width. Strictly
adhere to the
force-path-diagrams
of the drives.
For different drive mounting positions on the casement the
following points must be considered:
• Total weight of casement (glass + frame)
• Casement size (FAB x FAH)
• Snow load (based on snow zone / area of use)
• Roof pitch angle (important for snow load calculation)
• Wind force (infl uence of side wind)
• Required cross-section of aperture (geometric or aero-
dynamic)
• Required force and stroke of drive/s
03
Check:
• unequal force transmission to the window
• window statics allows unequal force distribution
• unequal casement pressure (tightness)
Snow load on roof windows for SHEV-systems
Example calculation
Establish snow loading based on national standards /directives
(in Germany according to DIN 1055-5)
total weight = FG + snow load
total weight = (40 kg + 60 kg) = 100 kg
Example:
snow load = 60 kg
(Casement area *
Typical snow load)
Example: FG = 40 kg
