Other than covering conduit in drywall is there any way or cables to give you two hour fire protection besides m.i.c.c.

Didn't even know conduit had a fire rating. What is the application?
If it's for something like a fuel farm (pumping station) you probably could not do better than MI, all in all, it does not come out a lot more than Rigid if you're running a bunch of it.
Walls are fire rated, the individual components inside them are dependent upon them to provide the rating. Many applications you do want to insure a low smoke in case of fire.

I'm still confused. Why would a supervised Fire Alarm system need a two hour rating? In the case of a fire, the system (hopefully) would have performed it's function in the vicinity of the fire, and any damage to the system wiring would be a moot point. Roger

That is the only place I have ever seen MI cable installed. Feeding a disconnect for a huge fire alarm panel in a shopping mall we used to service. It also fed the 480v., 100HP motor for the booster pump for the system. Before that I never even knew what the stuff was. Why not just use the MI?

You can't buy MI cable in a fire alarm rated configuration.
