Operating Instructions

When a Fire Fighter inserts the FFT Handset (FHS-F) into a remote FFT jack (FPJ-F or RPJ-F), the 
Answer Call LED will flash and the piezo will beep.  Pressing the Answer Call push-button in this 
mode will connect the local FFT Handset with the remote FHS-F.  Conversations between the two 
locations can be performed by pressing the Push-to-Talk switch on each FFT Handset.  To termi-
nate the conversation, unplug the remote FFT Handset (FHS-F) and press the Answer Call push-
button again.  Figure 3.15, “ACC-FFT Fire Fighter Telephone Module” on page 55, for additional 
information.
