977 / 977W Intercom
The 977 has all of the System 950 features and reliability but with additional ruggedness. All of its connectors are waterproof and its enclosure is weatherproof. It was designed with the marine application in mind.
- The modular system accommodates up to:
- 3 radios
- 10 crewmembers
- 14 positions including 4 radio-transit positions
- The System 977 is designed for the modern marine vessel.
- The System provides full-duplex intercom among all crewmembers and radio push-to-talk capability from four positions.
- Sophisticated electronics ensure that only the keying operator's voice transmits over the radio. When a crewmember keys the radio, all other microphones are locked out of the radio transmit circuit. Intercom communication between other positions remains active during radio transmission.
- Plug and play components and the fewest components of any leading system make the System 977 easy to install, saving time and money.
- Repairable parts decrease the lifetime cost of ownership and fast repair turnaround decreases downtime.
- Entertainment Audio Mute - Seamlessly listen to third-party audio devices connected to the System 977. When an incoming radio call is received, the entertainment audio is automatically muted so that the radio transmission can be clearly heard by all crewmembers.
- Advanced Electrical Noise Elimination - Public safety vehicles have numerous electrical systems which can cause significant noise issues for radio communication devices. The System 977 has electronic countermeasures to eliminate those potential issues and provide clear audio for crewmembers.
Common Marine Applications
- Interconnect cables are terminated with watertight, quarter-turn twist-lock connectors with gold-plated contacts and O-ring seals, eliminating any soldering or crimping required to install or replace components.
- Interconnect cables incorporate a shield on the microphone line and on the overall cable to prevent RF and EM interference.
- Radio transmit headsets can be used with a portable radio using an adapter cable (PRAC).
