The SK-FFT provides connection for a single Class B or Class A telephone audio circuit. See Section 4 and Section 5 for
examples of audio zone configurations. A monitor module can be used to monitor the connection of the Fire Fighter Telephone
remote handset (FFT-RHS) into the FFT-FPJ, which is then displayed on the SK-FFT active zone LED during the JumpStart
feature.
