Intercom Set "Circuit"

Professional GSM communication system from Zeronoise for communication between driver and passenger as well as via a Bluetooth mobile phone connection to the box.
The ideal solution for all applications where a connection via radio devices is not possible or desired.

The driver and the box communicate continuously via a Bluetooth-enabled mobile phone. The call is established and ended via the contact in the box. When the PTT (push-to-talk) function is activated, communication follows the rules of radio communication, meaning the driver must press the PTT button to speak; to listen, they release it. If the PTT function is deactivated, communication proceeds like a telephone call.

The team member in the pit can use the PTT button on the headset to communicate with the driver. The driver can respond directly.


The system is easy to install and easy to use.
No radio license required!
