departure switch
Order no. 9135251E
Description
The purpose of this module is to extend the 2N ® Helios Vario door communicator with
another switch, e.g., for switching the electric door to locked. It gives you features like
unlimited time switching or permanent switch during the time of the call or time limited
switching (selectable approx. from 1 to 10 sec.) via external button. Thanks to the
switching device - latching relay – it is now possible for switching the low voltage logical
inputs of e.g. gate and barrier control systems. Both normally open (NO) and normally
closed (NC) contacts between these and C are available.
Caution:
Before installing the module, make sure that the current and voltage limits of the module
will not be exceeded in your application (refer to the Technical Parameters chapter). In no
case use this module for mains voltage switching! All the wire connections make after
proper mechanical module installation.

one you will no longer need.

3. Insert board a (a little label on the module in brackets) onto the both contacts
moulding as on the picture below and fix it with a screw (longer one). Don’t forget to
