These are not hard

I assume you have every thing ready for and you want a door to be hackable or something anyway to be set off by hacking a panel

So Bind a the brush you want to a HackableWorldModel

Then in the HackableWorldModel set it properties to

HackTime How long it take to hack

OnHackedCommand msg Whatever Whatever

I used in the example
msg Hackable-Trigger trigger

When the hack time has elapsed the msg will be sent, I then used a trigger to control what happens This makes for a better pre-fab

Have look in the example and be creative
