AC and DC in the same conduit

[j rae]

Can you run AC ckt conductors in the samd conduit as Dc fire alarm plenum cables rated at 300volts? What code number?

NFPA 70 2008 760.136.

Normally no, unless 760.136 (D) Associated Systems Within Enclosures helps you.

Is this a power limited fire alarm circuit or non power limited?

Also the manufacturer may have instructions requiring separation.
