Arm/Disarm Aftermarket Alarm with Negative Pulse

Hey Guys, installing a digital guard dawg passive keyless entry system and push button start in my truck..

it uses rfid transmitters and when the key is close to the car it unlocks, when its leaves the proximity of the car it locks.

now i figured out how to arm and disarm the factory alarm with the negative pulse lock and unlock the keyless entry system provides, but i would
also like to add a new alarm into the mix that can send me alerts when the alarm is triggered on my smartphone, preferably one of the newer viper units.

the one requirement that i want is to not have to use the alarms key fob to arm and disarm the new alarm, i would like that accomplished with the rfid picks up im in range and out of range of the vehicle.

any idea of how i can accomplish this? currently using a DB3 to handle the immobilizer

thanks
