Animated Material

I have a scene with a camera movement setup in the matinee and I want to do the following:

When a camera fly near an object(which has an animated material on it) on a certain frame - start playing sequence once and then stop.

It seems like material plays its sequence in random repeat - no matter when you hit Play, it’s just constantly looping. Can I get it to start a loop exactly from the beginning and right after I hit PLAY button?
