Numerical call displays of the NDS series are electronic displaying devices, designed for calling clients in banks, public institutions, healthcare facilities, etc. They are controlled by a keypad with a control display, which is connected to the main display by means of a serial communication line. Besides displaying selected numerical values, the displays generate a melodic sound signal, which draws clients’ attention to the change of the displayed number. In the case of need, the function of the sound signal can be switched off by a program, controlled by the keypad. The displays are manufactured in the models suitable for mounting on walls, or with a holder for mounting on a levelled surface, or for hanging. With their design, they are suitable for the use in demanding architectural interiors. They are supplied in two colour versions – bronze and plattinum matt.
