This set is provided for smaller vessels where phone communication between only two points is required; between a flybridge and salon, or between motorhome driver and bedroom for instance. The PI-2 Set comes with two phone instruments, 40 feet (12 meters) of color coded, multi-conductor interconnect wire and all necessary mounting hardware. A single button on the base of each phone is provided for calling the other station. A buzzer sounds and an indicator lamp illuminates on the other station when the call button is pressed.

The PI-2 phone intercom is also available individually without the interconnect wire.
