Product Description

The Series 3800 Intercom System is engineered to solve the problem of communicating in high-noise environments with a mobile vehicle platform. Fire apparatus, rescue vehicles, ambulances, command and control vehicles, airline deicers and paint stripers are just a few applications that can benefit from the Series 3800 system.
