RTS Two-Wire Party-Line System
MCE-325 2- or 4 Channel 
User-Programmable Master Station
The MCE 325 is a four-channel, programmable 
intercom station. It may be used as a headset station 
or, with the addition of the MCS-325 modular speaker, 
as a speaker station. It may be mounted in a console 
or equipment rack via optional mounting kits. The 
MCE 325 can be used with either two-wire or four-wire 
intercom lines, or a combination of both. The MCE 
325 can be interfaced to a variety of external devices 
including external program sources, two-way radios, 
paging systems, and satellite circuits. The MCE 325 can 
be ordered for 4- or 5-pin operation.
803 12-Channel 
Programmable Master Station
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".
