Section 5
Audio Phone Circuit Installation

5.1 List of Devices

5.2  Maximum Number of Devices

The SK-FFT supports up to 48 zones. Each zone consists of one addressable 
monitor module (SK-Minimon) and a minimum of one Fire Fighter Telephone Jack 
(FFT-FPJ).

5.3 Wiring Requirements for the Audio Telephone 

Circuit

The following information applies to the FFT-FPJ Fire Fighter Phone Jack.

5.3.1

Single Phone Jack Audio Circuit in Class B 
Configuration

No special wire is required for the Audio Telephone Circuit. The wire can be 
untwisted, unshielded, twisted or shielded as long as it meets the National Electric 
code 760-51 requirements for power limited fire protective signaling cables.

54 Ohm maximum impedance - 12 to 18 AWG.

Twisted, shielded wire is recommended for maximum protection against EMI and AFI 
emissions and susceptibility.

If using shielded cable, attach the shield to Grounding Stud below TB6 of the FFT.

Note: Do not ground shield on both ends.
