Like all collective warning devices by ZÖLLNER, the ZPW16-31 is equipped with an automatic volume adjustment which regulates the level of the warning signal according to the surrounding noise. The result is a warning signal that is always as loud as necessary in order to protect the workers but, at the same time, as quiet as possible in order to protect neighbours and the environment. The ‘Autoprowa- Effect’ was fine-tuned even further in this new generation of warning devices and is now nearly continuously variable. It is therefore perfectly suitable for noise-sensitive areas as well.
Small green LEDs blinking in all four corners of the warning device show the active status of the warning system. If no LED signal warning device with the visual – neither the yellow warning signal lights nor the green status LEDs – is active, the system is not switched on. Since this allows anyone to see clearly whether the system is active and the worksite is thus secured, there is no need for temporary covers or the like to signal an inactive system.
