Important:
To minimize the possibility of crosstalk, care should be taken when running digital com-
munication circuits (for example, 12V digital keypad bus wiring, Burg SLC and Fire SLC circuit wiring)
in close proximity to each other, such as within multi
-
conductor cables or the same conduit over long
distances. All wiring must comply with the NEC (National Electrical Code) and/or NFPA 70 codes.
