Safety Overview
In accordance with country-specific safety regulations (concept of emergency exit, etc.) the doors are fitted with an emergency opening device.
6.1 Emergency opening with current supply
By activating the emergency opening switch (optional), which must be placed beside the installation, the door will open as long as the operating mode Locked has not been selected. In this operating mode the door will remain locked.
To re-start the installation, the emergency opening switch must be reset by hand, either through a rotation or a pulling (different procedures depending on the version of the switch).
6.2 Emergency opening in case of power failure with a back-up battery (optional)
- If a back-up battery is fitted and parametrized as 'Battery operation', all functions of the automatic door will continue to be available.
- In case of a power failure, emergency opening is ensured by a back-up battery that opens the door once (except if the program is set to 'Locked').
- The number of door openings depends mainly on door weight and the battery's charging state.
- The last door operation in case of a weak battery (insufficient capacity) is selectable: 'Open' or 'Close'.
- If the door is in the 'Locked' state, it can be unlocked by means of the key switch/push button (optional).
6.3 Emergency operating using Bowden cable (Option)
This device, available in several versions, is mounted inside and/or outside and allows the unlocking of the door, according to the procedure below.
