Loud signalling device for calling, warning and voice transmissions
The Variation EV 11 L is a high-volume compact signal generator with good directional effect. The chosen materials and the construction of the device enable outdoor use – even in the case of adverse ambient conditions.
The operator may choose between 7 different signalling tones, a 3-tone gong, and voice transmission. Make the adjustment at the device or externally via potential-free contacts.
Upon remote selection the device is continuously connected to supply voltage. The distance between the selector switch and an EV 11 L depends on the cross-section and the quality of the control wire (see Technical Data).
