Unique functions

Superior audio quality and ultrafast...

Conference Call

In a conference call talk group, an unlimited number of participants can participate in a discussion by means of an open connection. With a simple push of the PTT button, the user can enter into an active conversation and can also exit with the same ease. Multi group mode allows you to keep up to date with what is going on in the other talk groups, and you can also see what is happening in the background in the other talk groups.

Alarm function

In emergency situations, a user can report an emergency to colleagues and the control centre at the touch of the button. A single press of the emergency button will activate the alarm function and inform colleagues and the control centre. From then on, all recipients will hear what is happening on site, the location will be displayed, assistance can be started and help brought in.

Accessory Programmer

Lifeline accessories have been developed to align with the needs of users and their work processes in the best possible way. For certain work processes, it may be desirable to change specific settings. The Accessory Programmer allows users to set up, program and link accessories to the Lifeline platform.
