Setcom's most popular and versatile intercom, the System 900 was developed specifically for firefighters.

• With outstanding durability and a 12-year history, the System 900 is a top-quality intercom that has been put to the test by over 1,000 fire departments.
• This modular system accommodates up to three radios, ten firefighters and fourteen positions, including eight intercom positions.
• System provides full-duplex intercom among crewmembers and radio push-to-talk capability from the driver, officer and pump panel positions (driver and pump panel positions in parallel).
• 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 900 easy to install, saving time and money.
• Repairable parts decrease the lifetime cost of ownership, and fast repair turnaround decreases downtime.
• Interconnect cables are terminated with watertight, quarter-turn twist-lock connectors with gold-plated contacts and O-ring seals, eliminating any soldering 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).
