Sun protection and emergency exit

The § 33 Musterbauverordnung (MBO) - German standard building regulations - requires the exis- tence, for each floor, of at least two independent emergency exits.

One of them must comply with the regulations defining the first emergency exit. The first emer­gency exit enables people to quickly leave a danger zone. It leads either directly into the open air or into a secured area, such as corridors, stairs and exits.

Pictogram second emergency exit

Unlike the first emergency exit that is strictly regulated and clearly defined, the second emergency exit can be interpreted in different ways and faces countless solutions. Until now, uniform regulations have not been applied throughout the country.

For sun protection manufacturers, architects and planners, this represents a huge challenge in terms of design and implementation and might lead to conflicts.

Especially if the fire safety requirements for the second emergency exit are not respected. Further- more, aesthetic aspects, historic preservation regu- lations, constructive environment and, last but not least, costs have to be reconciled in a constructive dialogue.

The sophisticated design of the RESCUE-J can be easily integrated into all commercially available top rails. All components are dimensionally designed in such a way that only the crank handle has to be installed inside the building.

  • Space-saving: Thanks to its modular design, the system can be integrated into all top rails.
  • Flexible: The RESCUE-J is available for external Venetian blinds with 14 mm grooved tube or 12 mm square tube turning bars.
  • Maintenance-free: Motor, freewheel and gearbox require no maintenance. However, we recommend an annual check of the mechanical components by means of a test operation.
  • Customer-oriented: In an emergency, the external Venetian blind can be opened easily and quickly. The gear reduction 2:1 makes operation very easy.

RESCUE-J Kits components

  • GJ5606 Venetian blind motor (6 Nm): The basis is our mechanical Venetian blind motor, which has been tried and tested millions of times. Optimal and fast adjustment of the end positions with only two buttons.
  • Freewheel: Solid freewheel made of extremely stable and durable plastic. The freewheel is designed for 50 emergency operations and guarantees reliable operation over the entire service life of the external Venetian blind system.
  • Bevel gear: Proven components and modules ensure smooth operation. A patent application has been filed for the gear.
  • Airtight spherical bearing: Prevents cold bridges and protects against draughts and condensation.
  • AvantGarde crank: The elegant crank with concealed mechanism can be discreetly integrated into the room.

Operation in case of fire

RESCUE-J comes into action if the external Venetian blind cannot be opened electrically in the event of a fire. Simply pull the crank out of the holder, push the sleeve of the AvantGarde crank upwards and bend and turn the crank. The safety seal serves as a visual indication that the crank should only be operated in an emergency.
By operating the emergency hand crank, the freewheel is triggered and a regular clacking sound may be heard.


No action is required when recommissioning the GJ5606 drive. If the shutter has been opened with the crank, the crank should be turned a quarter of a turn in the opposite direction before being put back into operation in order to relieve the gear and prevent the crank from turning during motor operation.


Insert the motor with freewheel, dampers and the mounted coupling pieces into the top rail. Secure the motor with the clamping bracket/clamping bridge and lock it with the safety lever. Push the turning bars into the coupling pieces.
Insert the gear holder on the side and secure it with a screw if necessary. Insert the gear into the holder, paying attention to the alignment of the drive through.
If a specific direction of crank rotation is desired, the gear can be rotated axially by 180°.
NOTE: Operation by crank is only possible in the UP direction.
