760.136 Separation from Electric Light, Power, Class 1,
NPLFA, and Medium-Power Network-Powered Broadband
Communications Circuit Conductors.
(D) Associated Systems Within Enclosures. Power-limited
fire alarm conductors in compartments, enclosures, device
boxes, outlet boxes, or similar fittings shall be permitted
to be installed with electric light, power, Class 1, non?
power-limited fire alarm, and medium power networkpowered
broadband communications circuits where they
are introduced solely to connect the equipment connected
to power-limited fire alarm circuits, and comply
with either of the following conditions:
(1) The electric light, power, Class 1, non?power-limited
fire alarm, and medium-power network-powered broadband
communications circuit conductors are routed to
maintain a minimum of 6 mm (0.25 in.) separation
from the conductors and cables of power-limited fire
alarm circuits.
(2) The circuit conductors operate at 150 volts or less to
ground and also comply with one of the following:
a. The fire alarm power-limited circuits are installed
using Type FPL, FPLR, FPLP, or permitted substitute
cables, provided these power-limited cable conductors
extending beyond the jacket are separated
by a minimum of 6 mm (0.25 in.) or by a nonconductive
sleeve or nonconductive barrier from all
other conductors.
b. The power-limited fire alarm circuit conductors are
installed as non?power-limited circuits in accordance
with 760.46.
