Voice activated intercom systems with 2 to 12 crew stations, and up to 4 radio transmit positions. Will interface with up to 3 mobile radios.
Turn on instantly when you start speaking and turn off when you stop, which eliminates constant noise pick-up through the headset microphone.
Interfaces to single or dual mobile radios, allowing all communications, both transmit and receive, to be heard through each headset.
Compatible with cellular telephones. Contact us for information on using a Bluetooth cell phone with a Sigtronics intercom system.
Radio transmit is accomplished by way of the headset microphone through use of a push-to-talk switch. This design allows placement of the push-to-talk switch in the most accessible location and eliminates the need to reach for the hand microphone.
As an added safety feature, the intercom function is automatically disabled while transmitting so that only the voice of the person transmitting goes over the air, however his voice is heard by all crew members.
