MA - Are Repeaters unaffected by System Crash?

Ok, so I finally got to try Repeaters thanks to this week's Onslaught. I see that the reload time is 3 seconds. Yet, every time I use System Crash on a red with Repeaters equipped, they fire at me immediately without any reload time. Are Repeaters not affected by System Crash? I see they reload while firing, like beam weapons and railguns, but I've crashed mechs with those before and they go through a few second reload time after being crashed.
