The special dedicated forum section specifically for script questions is over ---------------->

You're way better off asking over there, you're more likely to get an answer.
As to the answer to your question, the solution isn't actually in scripting, it's in the model placed, open the models properties and scroll for the list, you will find an option called "allways active" with a yes/no drop down menu next to it, select yes and it will be always active across the whole map.
