Yes, there is most likely a prom chip in there that has a 4 diget code.
You need that code or another prom chip who's number you do know. Also,
earlier in you post you mentioned about putting a 1k resistor somewhere.
All alarm loops whether they have something hooked up to them or not should
be terminated in a 3k resistance.
