Retrofit intercom system for vehicles

According to EN 1789:2020, PTIntercom meets all the requirements of standards specifications. Whether emergency vehicles such as rescue services, fire departments, cash and valuables transporters, shuttle and cab services or delivery vehicles and trucks - PTIntercom is the optimal solution for various areas of application, ensuring simple yet secure communication.


PTIntercom is the central unit of an intercom system for fixed installation, in which two to four users (2- to 4-point communication) communicate with each other from a closed vehicle or between up to four spatially separated vehicle areas. If you would like more users to take part in the communication, additional units can be connected to the PTIntercom. You can select the right accessories for your application, such as handsets, hands-free systems, PTT button, LED light, potentiometer or switch for duplex or simplex mode, connect them to the PTIntercom and use them immediately (plug & play).
