Try another 12 volt source, and measure the preamp trigger out with a voltmeter. Make sure your connections are solid.
This may work, however the output @ 12v is 800ma which may be too much. Your local alarm store, like alarm warehouse or adi should be able to give you a relay that activates @ 5v w/ a transformer to step up to 12v output.Quote:

The company said yes. 5v for MAC trigger
SMS-1 needs 12v, so I guess I push a button.

sorry just took a closer look at that link, makes it alot more complicated than it needs to be. you basically need an ac to dc converter (wall wart) that has an output of 12v at what ever amperage you need ex. 200ma
now you need a relay that will close an independent circuit with a 5v input.
Should be like $10 worth of parts at your local alarm supply and they will be able to show you how to wire it
