either fiber optic cable or IDC. IDC circuits
penetrating the SCIF shall be filtered.
**************************************************************************
Wiring shall conform to NFPA 70. Wiring for 120 Vac power shall be No. 12
AWG minimum. The SLC wiring shall be [fiber optic] [or] [copper] cable in
accordance with the manufacturers requirements. Wiring for fire alarm dc
circuits shall be No. [16] [14] AWG minimum. Voltages shall not be mixed
in any junction box, housing, or device, except those containing power
supplies and control relays. Wiring shall conform to NFPA 70. System
field wiring shall be solid copper and installed in metallic conduit or
electrical metallic tubing, except that rigid plastic conduit may be used
under slab-on-grade. Conductors shall be color coded. Conductors used for
the same functions shall be similarly color coded. Wiring code color shall
remain uniform throughout the circuit. Pigtail or T-tap connections to
