Induction Loop Connection
The regulations that apply to communicator installations may require a mandatory
loop for persons with defective hearing in the lift cabin. In that case, connect the loop
to connector (10) with any polarity. The loop including a 1m long cable can be part of
your delivery if agreed.
Requirements
 The induction loop has to be placed behind a non-metal, non-magnetic cover
in the control panel because the magnetic field of the induction loop cannot go
through the metal control panel.
 The induction loop has to be labelled with an appropriate symbol (ear) placed
according to applicable standards.
