Page/Party® Radio Coupler (VHF)

The Model 370-420 VHF Page/Party® Radio Coupler enable a GAI-TRONICS' Page/Party® system to communicate with wireless radio systems. Radio users, whether outside the facility at a remote location or inside the plant, can seamlessly communicate with Page/Party® users. The coupler combines interface circuitry with a radio module in one compact unit. The coupler operates in a half-duplex manner; audio is only heard in one direction at a time. Audio direction is controlled by a VOX circuit on the Page/Party® side, and a carrier detector on the radio. The coupler converts audio levels from the Page/Party® system to an appropriate level for the radio. Audio is then transmitted on the selected frequency programmed into the radio.
