Not sure what a simulation file is. I just programmed it directly in PICBasic Pro. For the sounder you can use any piezo that is self resonating and have a voltage of 5 volts and a current draw less than 25 mA.
Yes, you can find the code here.
You will need PICBasic Pro to modify it.
Thanks, PICBasic PRO from ME Labs
That project was only featured on Hacked Gadgets, there should be a link in the article to additional information.

I am not exactly sure but I think it was a Kenwood.
Yes, you can find info here.
Not yet. Please check back in April.
There is an low voltage, low current output that can be used for whatever you want in this version. The unit does not come in a housing however one can be purchased locally. There are lots of generic alarm cabinets that would work just fine for this unit.
You can make it say whatever you want.
