Common Telephone Riser FFT-7/FFT-7S Fire Fighter's
Telephone to an XP
Transponder XPC-8
Module.
24 VDC (nominal), 1-Vrms max. 800 Hz to 2800
Hz. Seven (7) telephone handsets active at one
time max including Master Telephone.
Supervised/power-limited. Two-wire circuit
supervised via 27K ELR, Part # R-27K (N-ELR
for Canada). Optional return loop for 4-wire
circuit. Max wiring resistance (including
individual telephone zone to last handset.)
permitted is 40 ohms. 10,000 ft. max wiring
distance at 12 AWG to last handset.

to XPC-8 Connector P3.2 (+), P3.1 (-), and/or
P4.2 (+) P4.1 (-), P5.2 (+) P5.1 (-), P6.2 (+)
P6.1(-), P7.2 (+) P7.1 (-), P8.2(+) P8.1 (-), P9.2(+)
P9.1 (-), P10.2 (+) P10.1 (-). Optional four-wire
redundant return to FFT-7FFT-7S Connector P3
Term. 6 (+) and 5 (-) to XPC-8 Connector P10.

XP Transponder XPC-8
Module fed from an
FFT-7/FFT-7S: Employs
phone jacks APJ-1 and
FPJ; Fireman's Handset
FHS-1; Fireman's Handset
Enclosures FHE-F and
FHE-S.
No telephone jack maximum per circuit.
Two-wire circuit supervised via a 47K ELR, Part
# R-47K (N-ELR in Canada). No outboard ELR
for four-wire supervised circuit. Max resistance
due to wiring is 40 ohms from FFT-7 to
termination of the telephone circuit. Power
limitation is a function of the signal source
employed.
