Induction Loop for Lifts

Emergency communication from lifts for people with hearing disabilities

2N® Induction Loop is an induction loop which is part of the lift cabin audio system. Once connected to an audio source such as a lift communicator, the induction loop transfers sound to a hearing aid with a built-in induction sensor. This allows people with hearing disabilities not only to hear and perceive sounds better, but also to understand speech. 2N® Induction Loop is therefore an essential aid when designing emergency communication from lifts with hearing aid users.

Product highlights:

2N® Induction Loop for lifts complies with the requirements of standard EN 81-70 and can be used with any device emitting an audio signal. It is compatible not only with lift communicators from 2N (for example 2N® Lift8 and 2N® SingleTalk), but also with devices of other manufacturers.
