2.6 FPJ-F Installation
The FPJ-F Firefighter Phone Jack mounts to a single-gang electrical box (4 x 2⅛ x 2½) or, when
the addressable mini-monitor module is installed with it, a deep single-gang electrical box (4" x
2⅛" x 3¼").
Connect the telephone audio loop between the FPJ-F and FFT as detailed below. All circuits are
power-limited and supervised.
