Jeron's Spectrum 430/460 Digital Duplex Intercom System provides the unique advantage of having a central communication system, which integrates with a facility's security system. Spectrum completely integrates with a single PC, running security software or an enterprise-wide command and control network. Spectrum's RS-232 interface allows for seamless integration with remote control systems and Programmable Logic Controllers (PLC's) to coordinate video camera control, lights, doors and the use of graphic annunciators. The digital voice quality and audio monitoring that Spectrum provides enhances security throughout your facility. Spectrum allows for complete access control with two-way communications from station to station. In addition, for duress situations Spectrum substations have one-touch pushbutton activation to place calls to the master handset or emergency personnel.
