Connection of indication elements (LED)
The current technology of LED production makes it possible to achieve relatively good
light intensity with a small current. Because the indication elements of the lift are
illuminated by a sufficiently powerful LED for which a current of around 5 mA
is
sufficient (with a drop on the diode of around 2 V), it is possible to get by without a
source. In this case connection corresponds to the following picture.

Connection of induction loop
During the installation of the communicator it is necessary to abide by current
regulations, which may designate the installation loops for the hard of hearing as a
mandatory part of the communicator in the lift cabin. The loop is connected to the
connector (10) with any polarity. Following agreement it can be part of the delivery,
including cable 1m long.
Warning
Non-adherence to these instructions could result in damage to the
product.
Caution
Delayed calling must be programmed in order for the connection of the
CANCEL input to make sense.
Configuration of ALARM and CANCEL is depicted on the cover of the
electronics.
Note
The cables for are not a regular part of the delivery, only after prior
agreement.
When using this connection the ancillary control lamp is not illuminated on
the printed circuit.
