Vehicle Intercom System

David Clark Ground Support Military Headsets

Series 3800 Vehicle Intercom Systems provide COTS solution for communicating in high-noise environments, especially those associated with fire/rescue and emergency operations during call response and at the scene. Personnel on the apparatus are able to communicate clearly, without interference from loud vehicle noise, sirens and horns.

This COTS system provides the option of connecting to mobile radios, allowing all personnel to listen to the radio and selected stations to transmit. Representative system components, including noise-attenuating headsets and headset station modules are listed below.

For additional Series 3800 Vehicle Intercom System components, visit the Fire/Rescue section of our website.
