The RTS

 model 803 master intercom station is the hub for the two-wire intercom 
system. Call signaling is standard on all twelve intercom channels. For applications 
requiring four-wire operation, IFB panel emulation or ISO panel emulation the circuitry 
is already there; you simply install an option cable to the back panel, set one or two 
internal DIP switches (IFB and ISO emulate only) and you’re ready to go. For all other 
applications, everything you need is “in the box”.
