Need opinions here:
We are having a new Fire Alarm installed in one of our buildings. Some of the new Fire Alarm EMT is installed above the bar joists, tight to the roof deck. We're on 2008. I've been thru 760 several times and can find no ref to 300.4. Therefore I need opinions:
Based on this section
760.3 Other Articles. Circuits and equipment shall comply
with 760.3(A) through (G). Only those sections of Article
300 referenced in this article shall apply to fire alarm
systems.
Does this section apply?
(E) Cables and Raceways Installed Under Roof Decking.
A cable- or raceway-type wiring method, installed in
exposed or concealed locations under metal-corrugated sheet
roof decking, shall be installed and supported so the nearest
outside surface of the cable or raceway is not less than
38 mm (11⁄2 in.) from the nearest surface of the roof decking.
