I want my keyless entry to turn an alarm on and off. What brand and model alarm can do this?

Thanks Audiokid. How does it know to arm or disarm?

The systems tie into 3 wire connections on the truck for this.
Driver Door Lock Motor
Driver Door Unlock Motor
Passenger Door Unlock Motor

If the alarm sees a 12V pulse on the door lock motor wire then it knows to arm.
If the alarm sees a 12V pulse on only the driver door unlock motor wire (driver priority unlock from OEM fob) then it knows to disarm.
If the alarm sees a 12V pulse on both the driver door and passenger door unlock motors at the same time (as if someone reached through the window and pressed the power unlock switch) then it will not disarm.
