Each Main (master) unit (LM6) and eve unit (LM6-CVC) has a paging/ music input. This is the GREEN wire
(25V) and BLACK wire (COM). Both units also have a paging volume control. This control is factory set
in MID position. Connect the GREEN wires of all Mains and eves of a particular paging zone together
to create a home run. Do the same for the BLACK wires . Connect this home run to the 25-volt output
terminal of the paging power amplifie . GREEN to 25V, BLACK to COM.
In order to utilize a telephone paging system, a telephone interface module is required. This can be a
BSS03, BSS06, BSS09, or other telephone decoding system.
