In a firewall, I have to use rated steel boxes for my electrical work. Doesn't the use of these "data rings" by the low voltage crowd destroy the rating of that firewall?

Have to admit even I am guilty of that from time to time.

I would say yes, a steel box should be used depending on the rating of the wall and the proximity to any other boxes.

When I was doing "Data" we had to respect "penetrations" just like everyone else. The problem is data doesn't usually get permitted/inspected. You will get caught by the life safety inspector, usually as part of an unrelated inspection.
In the case of this picture he would be looking at the exit light and say "that ain't gonna work" when he sees the other hole in his firewall.

Don't get caught defeating the rating of a firewall. The liability of that is NOT worth it.
Go to Hilti.com, and look under firestop products. There is some good info there.

Heck ya, it does!!!

Typical installations in my area (Southern California), for _ANY OUTLETS_ in rated walls / lids, is as follows:\

<OL TYPE=A>

[*] The outlet would be (compatible to) a 4s box, with a 1 (or 2) Gang Ring mounted to it,


[*] The 4s Box would be covered with a "Fire Pad",


[*] The Low Voltage Cabling would enter the box via 3/4" EMT, which extends "Outside" of the rated wall / area.

Scott, my original intention in posting this pic was two-fold:

I wanted to illistrate the importance of knowing more than just "your" part of the code; and,

I wanted to shame some data guys out there into actually thinking about how they're supposed to do things- as opposed to using all the short-cuts they've been able to get away with, as their work takes place after the inspector has left!

You are wasting your time. Data guys, better known as computer geeks, have no shame.

It's only after a fire that these things are picked up by investigators.
Fire-walls aren't put there for the sheer fun of it.
These people should be made an example of.

Part of my job was to teach them some shame ... or at least to get the problem fixed and get their boss a bill.
