4.5.11 Fire Fighter Telephone: ACC-25/50ZST Only
The ACC-25/50ZST provides a telephone interface for up to 24 remote FFT jack locations and per-
mits up to six (local phone handset plus five FHS-F remote phone handsets) simultaneous connec-
tions. Two available styles of remote FFT jacks are the FPJ-F and the RPJ-F, both providing a
standard audio plug interface for the FHS-F handsets. The RPJ-F also houses a keyswitch for
remote paging operations.
S3 switch 7 on the ACC-25/50ZST motherboard (ACC-MCB) must be
set to
ON
.
Communication on the Telephone Loop
When a Fire Fighter plugs the handset into one of the remote FFT locations, a ring-back tone will
be heard at the remote location, the Answer Call LED will flash and the piezo will sound on the
ACC-FFT module located in the ACC-25/50ZST main panel. The user at the main panel can
answer the remote call by picking up the local handset and pressing the Answer Call pushbutton,
which turns the Answer Call LED on steady and terminates the ringback tone. Both parties can
now converse by depressing the respective push-to-talk switch on the handsets.
Additional handsets (up to 4 more) can plug-in and converse in a party-line format. Proper termi-
nation of communication requires that all remote jacks be unplugged and that the Answer Call
pushbutton be pressed. If this procedure is not followed, a system fault condition will occur.
