dead siren output suggestions?

DEI model: 554R alarm/RS Problem: dead siren output After relocating my Valet 554R alarm/RS I decided to add my emergency light flasher as an output when the alarm is triggered. For four years the siren output has powered an exterior and interior Revenger siren with no relay. After diode isolating the siren output from the 12V+ switch to the flasher module it no longer works. Apparently this was just too much juice for it to handle, and to think I was going to use a relay first. The light flasher and sirens all tested fine. The siren output tests dead when the alarm is triggered, even after a hard reset. Everything else on the alarm works. I pulled the brain out of it's shell, and something small is browned (not sure what it is, but it's not a capacitor, resistor, or diode). Though I can't figure out what it is, I can only assume it's part of the siren output circuit. Since my 554R has been discontinued for some time now, I cannot find a used one to replace mine. I also cannot find a definitive list of what is closest in capability. It seems my only options are to either wait around for a used brain to show up on ebay sometime, or to buy a new system and install it. I would like to avoid buying a new system, and would prefer to buy something older that is compatible with what I have now and do a little wiring if I have to. Getting a replacement brain would be ideal if I could find one. Suggestions?

what did you have in mind t&t?

do dei units have programmable outputs for example changing a wire function to something else via bitwriter?

Is there a component name silk screened on the circuit board next to the Browned device?  If so, what is the letter in front of the number?

Can you take a picture of the damaged component?  I would assume it is either a resistor or a transistor.  At the component level it shouldn't take much to fix it. Kevin Pierson

t&t - Yes, it does have a programmable parking light output. Thanks for the idea, and I think I will try that route. KPierson - I was thinking I might be able to get it fixed as well, as long as I bring it to someone who knows and can work on things on that level. I will try to get a picture of it today or tomorrow. Thanks guys, I appreciate the help so far.
