Emergency Releases

According to the state of the art (EN 81-20) an emergency release triangle in horizontal installation position must not be installed higher than 2 m above the floor.
Also the accessibility of the release from the shaft is now standardized. For this reason all Kronenberg door locks have been extended with the option.14 for connecting a Bowden cable and the option .5 for connecting a pull cable to open the door lock.

The triangular emergency release units type NE are provided for actuation of the cable pull or Bowden cable attached to the door lock. On request they can be equipped with a safety switch for monitoring the emergency release as required in EN81-21. An option with bistable switching function and electrical reset is also possible.
               

Please find an overview of cable pull and Bowden cable connections here as well as the corresponding operating instructions.

For any further questions about the “external emergency releases” our sales team will be pleased to advise you!
