Having Pearl ABS enemy aggro upon being hit

I'm currently using Proximity Events by V.M. in order to get a sneaking effect.

I also added Pearl ABS v3 in order to simulate gunplay.

The issue is that I'm trying to get an event to return fire (with self switch C) if any of the two conditions is met:

   1) The player is within detection range of the event.

   2) The event is hit by a player attack. (at range)

The first I managed to do quite simply, but I can't seem to find a means to check if an event was hit. 

Is it possible to have the event turn self switch C on after being hit? Am I just missing it?

Thanks in advance. :)

EDIT: I found my exact issue here, but the poster hasn't posted his solution to the problem. Perhaps it can provide some more clarity as to what my issue is? http://www.rpgmakervxace.net/topic/8809-falcao-pearl-abs-liquid-v3-update/?p=113896
