The V-9936A may be GENERATOR used with most telephone systems because it connects directly to the lines and not to the phones. The tone output may be connected to speakers used only for ringing or to one zone of a paging system. The dry contact closure may be used to activate loud FIGURE 1 - TYPICAL INSTALLATION ringing bells, strobes or other external equipment. Both outputs will provide interrupted signals INSTALLATION whenever any line is ringing. The following sections contain step-by-step instructions for wiring the V-9936A and associated A disable input is provided for connection of a night Valcom equipment. Each instruction is preceded by a switch. With no switch connected, the V-9936A will line; place a check on the appropriate line as the signal any time a line rings in.
