The EV11 Varioton sounder is a loud, compact signalling device with good directivity. The materials used and the design of the device allow it to be used outdoors – even in difficult enviornmental conditions. Users can chooce between seven different signals, a three-tone chime and voice transmission. The signal is set either directly on the device or externally via potential-free contacts.
In the case of remote control the supply voltage is applied to the device constantly. The distance between the selector swtich and an EV11 device depends on the cross-section and quality of the control cable.

The device comprises a unit consisting of power supply, sound generator, amplifier and loudspeaker. The housing is made of seawater-proof aluminium with an epoxy-coated surface.
All external screws and the loudspeaker bracket are made of stainless steel. The electronics mounder in the IP 55 housing are protected against moisture by a special treatment. The signalling device is very easy to mount. To connect it, the hinged cover is opened wide or removed completely. The pressure-chamber louspeaker is rotatable and traversable.
