AVCOMM International's EasyLink SC800 Intercom is a powerful, flexible intercom system designed for the extreme conditions of EMS or fire vehicles. Featuring AVCOMM's EasyLink design, the SC800 virtually eliminates tedious soldering for easy installation. AVCOMM EasyLink jack boxes, pre-wired and pre-assembled, provide the connections for a flexible intercom system that can be easily expanded or modified for additional positions or remote PTT's without having to completely rewire the vehicle. The SC800 has a solid extruded aluminum framework to dramatically reduce radio frequency interference, thermoplastic elastomer gaskets to seal out moisture and dust, and an easy-attach U-bracket mounting.
