Fire Control Instruments has introduced the NetSOLO® Broadband distributed audio system. NetSOLO Broadband delivers full-network control and communications, digital messaging, live voice instructions and fire fighter telephone communications through a distributed network fire alarm system, all on a single pair of wires. Because NetSOLO incorporates existing 7100 panels, the system doesn't need to be redesigned and can be expanded as the user's application grows. It uses Boolean logic programming and a state-of-the-art Digital Signal Processor.Fire Control Instruments.
