Intercom systems
Full-duplex intercom systems for wireless and wired communication for police, fire brigades, rescue services and the military
Here you will find our wireless and wired intercom systems. As with telephony, you can listen and speak at the same time (i.e. full duplex operation).
In contrast to two-way radios, where only one person can speak at a time and you also have to hold down a PTT (push-to-talk) button while speaking. With our duplex solutions, you have your hands completely free and can concentrate fully on your work or the actual activity.
When using the radio, you always have to wait until the other person has finished speaking before you can speak yourself by pressing the push-to-talk button. However, there are often applications and situations where it is absolutely necessary or safety demands that one or more people must always be able to speak simultaneously and immediately. In these cases, the use of one of our intercom duplex systems is recommended.
Our wireless full-duplex systems can be used in the following areas of application, for example:
Intercom system for fire brigades (e.g. for the communication of breathing apparatus teams)

Wireless full-duplex intercom system with radio gateway
This brand new wireless full-duplex intercom communication system Grand Multicom Pro allows the formation of several groups with up to 10 participants each that can talk to each other. The groups can be linked together via the radio gateway with PTT function, so that communication between several groups is also possible over longer distances (even over the entire coverage area with TETRA digital radio).
The crystal-clear communication is encrypted in the 2.4 GHz band and the devices are certified with protection class IP67.
Intercom for Invisio communication systems
The INVISIO Intercom System ICS (INV15696) allows multiple users and radios to be connected simultaneously, using the soldier’s existing system. The soldier can access all vehicle communications directly from his INVISIO control unit. The soldier does not have to put on or take off his equipment when entering or leaving a vehicle.
This enables secure and seamless inter-group communication and connection to the intercom system. Any vehicle communication platform can be integrated with minimal effort. The system is lightweight, plug-and-play and unrivalled in its compactness and manageability, allowing troops to move anywhere while maintaining communication. The INVISIO Intercom System enables seamless transitions between land, sea and air forces while maintaining
hearing protection and full situational awareness at all times.
Brand new: Via Invisio Link Base Station, which is connected to the intercom base and via Invisio Link Dongles, which are plugged into the control units e.g. V20/V60, the intercom communication is also transmitted wirelessly and the users can move with full communication e.g. outside the vehicle.
Vokkero Guardian full-duplex wireless radio
With the Vokkero Guardian full-duplex system, everyone can hear and speak at any time without having to press a (talk) button. With the Guardian Standard, you can easily and reliably set up a conference system with crystal-clear and perfectly intelligible communication. Even under extreme noise conditions, ensuring the productivity and safety of your work teams.
The range is up to 1.2 km without repeaters and relay stations!
Sordin Share wireless intercom hearing protection headset system
Some professional teams need to stay in constant contact with each other to get their work done safely and efficiently. Sordin Share is designed for them. With in-built intercom functionality for multiple participants, this state-of-the-art electronic hearing protection breaks down the barriers of teamwork. It is based on DMC™, a proprietary mesh network technology that works anywhere – without internet access or a dedicated base station.
With the Sordin Share app, you can easily set, customise and use the many functions. It is just as simple and intuitive as you would expect from any modern smartphone app. The functions range from selecting a work team to customising your personal audio environment.
Axnes Intercom radios
MP30 and MP50 intercom radios and base stations for communication in extremely difficult environmental conditions.
Clear communication via full duplex, adaptive noise cancellation and echo suppression. Interruption-free VOX enables crystal-clear communication in the noisiest environments. Push-to-talk operation is also possible. The radios can be combined with many different headsets depending on the application.
They are typically used on boats, ships, helicopters, armoured vehicles or for mobile units on land. The devices can also be combined with other radio devices (e.g. marine radio) or communication channels via base stations so that all group members always receive all information.
