Product Code: FOR22
4-WIRE/2-WAY RADIO INTERFACE (DUAL)
The FOR-22 connects two external 4-wire circuits to the matrix. Camera
intercoms, two-way radios, microwave and satellite links, IFBs, and program
audio inputs and outputs are candidates for the FOR-22. The module provides
proper impedance matching, transformer isolation and level adjustments between
systems. It also supports external relay activation and call-sense circuitry.
The relays can be controlled separately to add to the frame relay complement.
