Bulldog RS602E help.

Hey guys, I'm installing a Bulldog RS602E in a friends car, and I don't know what to do with the shock trigger inputs.. He bought the dual stage shock sensor, and a dual stage dopplar sensor, but the RS602E only has a one wire trigger, not dual. I wanted to know if there was a simple circuit I could build from relays to make use of the dual stage by kicking the siren trigger line a few short times to simulate a pre-warn tone. Any help would be appreciated. TIA -Sean

No one has any help they could offer? I just need ideas on a simple relay ciruit to intermittantly hit the siren to simulate a pre-warn... thanks..
