Clear-Com CS-702 2 Channel Headset Main Station Intercom

The CS-702 provides visual indication of power supply conditions. In the event of a DC short circuit or current overload, the station’s electronic overload protection circuit will shut down the DC output to
avoid damage. As soon as the fault condition is removed, the auto-reset circuitry will automatically restore system power even under full load conditions. There is no need to disconnect stations to allow the power supply to reset.
