Remote start sets off alarm (sometimes)

yea, eventually I want to rip the whole thing out and put in a single unit that does everything. But, it's not my car so I'm not allowed to just yet

HEY!!! Can you believe that the voltage sense was set to on!?! I finally got a chance to check it, and I turned on the headlights first, and the alarm went off! I tried the domelight and the brakes too, and the alarm went off. So I finally opened the little door on the alarm, and moved the dipswitch to off. Funny thing happens, though. As a reminder, I have the extra channel on the Checkmate remote activate the remote starter so she only needs one remote. If you use the Bulldog remote or the Checkmate remote to start the car, the alarm doesn't go off (WAHOO!). If you use the Bulldog remote to shut the car off, the alarm goes sounds....but if you use the Checkmate remote, it works fine. Any ideas? Is this because I don't have a diode on the 2 relays previously mentioned?

anyone got an idea to my poor little problemo? It works with the Checkmate remote (on and off), but it sets off the alarm if you turn off the remotely started car with the bulldog remote.
