The 685 is truly the ultimate in digital communications. A receiver so versatile, it can make a dramatic difference in the overall central station efficiency, the moment you put it to work.
It starts proving its worth by accepting transmissions from virtually any communicator in service, including Honeywell Home VISTA systems with high-speed, 4+2 Express and Contact ID formal. It's compatible with Honeywell, Sescoa and Radionics formal, Versus Derived Channel and AlarmNet/Honeywell 900 MHz Long Range Radio formats.
The 685 can also accommodate up to eight phone lines, each with built-in line fault monitoring, and process calls on all lines simultaneously.
