Solution for external venetian blinds in the 2nd escape route
The requirement in accordance with Section 33 of the Model Building Regulation (MBO) demands at least two independent escape routes per floor, at least one of which must comply with the regulations of the first escape route.
The first escape route is a traffic route that enables people to leave a hazardous area quickly. It leads either out of a building into the open or into a secured area. Examples include corridors, stairs and exits, which people use to escape to safety in the event of a fire.
In contrast to the first escape route, which is strictly regulated and clearly defined, there are countless possible solutions when designing the second escape route. Whether you consult the MBO or other state building regulations, you will not yet find uniform regulations nationwide.
For sun shading manufacturers, architects and planners, this represents a massive challenge in terms of design and implementation. This in turn can lead to conflicts. Especially if the fire protection requirements for sun shading in the second escape route are not taken into account. Furthermore, aesthetic aspects, monument protection regulations, structural framework conditions and, last but not least, costs must be reconciled.
The ingenious design of the RESCUE-J can be easily integrated into all standard top rails.
All components are dimensionally designed so that only the crank handle needs to be installed inside the building.
Slide 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 locking lever. Insert the turning rods into the coupling pieces. Insert the gearbox holder on the side and secure with a screw if necessary. Insert the gearbox into the holder, paying attention to the alignment of the drive bushing. Suitable fastening of the spherical plain bearing plate must be checked and guaranteed by the customer! If a specific direction of crank rotation is required, the gearbox can be rotated by 180° axially.
NOTE: Crank operation is only possible in the upright position and is only intended for emergency operation.
If the external venetian blind cannot be raised electrically in the event of a fire, RESCUE-J is used. Simply pull the linkage out of the bracket, push the sleeve of the AvantGarde crank upwards, bend the crank and turn it. The safety seal serves as a visual indicator that the crank should only be operated in an emergency.
The freewheel is triggered by forcefully operating the emergency hand crank, whereby a regular clicking sound can be heard.
If the upper position was set by the limit stop switch, no action is required when restarting the GJ5606 motor. If the upper end position was set to position and the blind was manually cranked over this position, the upper end position must be reset. If the blind was opened using the crank handle, the crank handle should be turned a quarter turn in the opposite direction before commissioning in order to relieve the gearbox and prevent the crank handle from turning during motorized operation.

The system is maintenance-free. However, an annual test run is recommended to check the system. The occupants or employees in the premises secured by RESCUE-J should be instructed in its use.
