I want to add a dual stage sensor to my VSC3400

Hello

I have a General Motors add-on alarm (VSC3400) on my 2001 GMC truck. This alarm system is made by DEI, but is sold under the General Motors name. It disables the factory alarm and it uses its own alarm brain. The reason why I chose this is because the factory alarm can be turned off if someone jams a screwdriver into the door lock. The VSC3400 can only be turned off with the remote or from the valet switch.


I would like to add a DEI dual stage radar/microwave interior sensor that has a warn-away feature. The sensor has two trigger wires; blue and green. I think the blue is instant and the green is warn-away (irrelevant for now). The warn-away trigger has a short pulse (0.5 seconds??), and the instant trigger has a long pulse (2.0 seconds).


There is a green wire and a blue wire coming from the VSC3400 computer brain. If I connect the wires to the green I get a 3 chirp warning, but the alarm still goes off afterward. If I connect to the blue wire the alarm goes off instantly. I cannot find anything in the instructions that tell me how to get a warn-away chirp, but not continue to set off the alarm. I am guessing that this feature is not enabled in the VSC3400 unit

This should be the link the VSC3400 install manual. https://www.the12volt.com/installbay/downloads.asp?srch=all&term=vsc3400

I looked in the "relays" section of this website to see if I could attach the dual stage sensor's green "warn-away" wire to the horn/siren separately instead of to the VSC3400 brain, but I couldn't find anything.

Can I attach the green wire directly to the siren? I do not know how much amps the siren draws.

For anyone interested, I installed a DEI 528T Pulse Timer Relay, but I had a a problem with the length the siren is one.
