SCI-6 Intercom

Pilot Isolate
All the features of our stereo pilot isolate series in an FAA TSO approved intercom only (no music capability) package. The SCI-4 four place and SCI-6 six place offer dual volume and squelch, three modes of operation: All, ISO, Crew, and includes our fail-safe feature. By placing the intercom in the ISO mode of operation, the pilot's microphone and headphone are routed directly to the aircraft radios.

Small Size
This powerful intercom can be mounted horizontally or vertically and needs only 1" by 2.5" of panel space. Only a minimum of rewiring is required to upgrade from a SPA-400 / 600. By using your existing interface cable and the included pre-wired harness and hardware, upgrading to a SCI intercom is fast and easy. The SCI Series intercoms are constructed of high quality components and carry a 5 year parts and labor warranty.

Upgrading from a SPA-400 or SPA-600 to a SCI-4 or SCI-6 is easy. See our Upgrade Overview information below for the wiring changes. In Adobe PDF format.
