FT5 S TETRA Handset

High End TETRA Radio for health & safety in the workplace

The FT5 S is Funktel's newest TETRA handset developed for optimum personal security in the workplace. It is certified under German law for dangerous workplaces and provides a full range of unique health and safety functionalities. The large emergency button ensures fast reaction in case of an emergency. With 4 manual alarm types and 4 automatic alarm types, the FT5 S is well-equipped for all kinds of sos signalling. Thanks to the simultaneous work of three separate localization technologies and contactless guard control, help can always be quickly sent to the right place.

The FT5 S is considerably smaller and lighter than its predecessor of the FT4 line, making the device easier to handle than ever. Nevertheless, the handset is extremely robust and shock resistant. With its rubber coating, the FT5 S easily withstands falls from great heights, and is also protected from dust and water jets (IP 65).

With its 4 way satellite receiver, the smart-ready Bluetooth module and the inductive localization module for exact indoor localization, the FT5 S is a state-of-the-art TETRA handset that meets highest demands for safety and user comfort in the most demanding circumstances.
