David Clark U3800 Master Station Overview:

Series 3800 Vehicle Intercom Systems are engineered  to solve the problem of communicating in high noise environments, especially those associated with emergency operations during call response and at the scene. They enable personnel on the apparatus to communicate clearly, without interference from vehicle noise, including sirens. They have the option of connecting to mobile radios, allowing all personnel to listen to the radio and selected stations to transmit over the radio. 

The "heart" of the Series 3800 Vehicle Intercom System. One each is required per system. The U3800 will accommodate two headsets and should be placed where radio transmit function is not required. Adjusts automatically for 12 or 24 VDC power source. Contains system on/off, master volume control, two headset jacks with listen level controls, power input connector, and two remote output connectors. Draws less than 600 milliampere current. 8-1/4"L x 5-3/4"W x 4-3/4"D.
