Comm cable routing through fire rated wall

[steve66]

Is a sleeve required where communications cables run through a fire rated wall?

These are existing cables that run through the wall of a computer room (Article 645 room). The cables are sealed with fire rated caulk. But there isn't any sleeve or conduit stub through the wall.

We normally specify a sleeve, and that's what I normally see, but I don't know if the sleeve is required per code.

If the cable is listed to penetrate a fire rated wall I would guess that there is no requirement for a sleeve. Similar to when MC cable penetrates the same wall without a sleeve.

This is standard Cat 5 data cable, so I'm not sure if it is listed to penetrate a wall.

Is that fire caulk just on the surface or does it have the min/max required annular thickness and depth. Looks like it's just slapped on top.

There are tested through penetration assemblies that just use fire caulk. What you describe would be acceptable if it meets the conditions of a tested assembly. Here is an example of a tested assembly from the UL web site.

The code doesn't specify how it is to be done, it just requires that a tested assembly be used.
