The new FM6 GSM PES device is the ideal solution for the safeguarding of personnel in hazardous solitary workplaces. In an emergency, the device alerts an alarm control centre when a pushbutton alarm is pressed or when a will-independent (automatic) alarm such as a position, no-movement, fall, flight or time alarm is triggered by the integrated sensor systems. In the process, precise localisation information is transferred so that assistance can be provided to the casualty swiftly and in a targeted manner. The localisation function, using a built-in ISM band radio module, is especially noteworthy as this also assures that an alarm can be provided in areas that do not have GSM coverage.
