RTS 803 Master Station
The RTS® model 803 master intercom station is an updated replacement to the popular model 802. By employing many of the technological breakthroughs that have occurred since the design of the 802, RTS® has been able to integrate into the 803 the complete circuitry for all 802 base features and options except squawk.
For example, call signaling is now 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".
