Strobing the mask effectively blinks between your mask settings and a solid screen of your mask color. As long as you haven't applied the mask color effect and colored your mask, you are basically strobing between blackout and your current mask settings. If you need to sync this between units, you can accomplish basically the same thing by applying a step wave to the global layer intensity within the console effects engine. This would then be synchronized across all of your units.
This won't work with colored masks, but should take care of other situations. If you have a spare layer, you can also synchronize the strobing of colored masks by adding a top layer that is the same color as your mask and applying a step effect to that layer's intensity.
