In compliance with NEC Article 760, all power limited fire protective signaling conductors must be separated a minimum of ¼ inch from all of the following wiring located within a control panel:
- electric light
- power
- Class 1 or non-power limited fire protective signaling conductors
To meet these requirements, the following guidelines must be observed when installing modules and wiring to this control panel.
When installing power limited field wiring, the installer must comply with NEC article 760-54, which states:
The fire alarm power-limited circuits are installed using Types FPL, FPLR, FPLP or permitted substitute cable, provided these power-limited cable conductors extending beyond the jacket are separated by a minimum of 0.25 in. (6.35 mm) or by a nonconductive sleeve or nonconductive barrier from all other conductors.
