Does anyone know the cycle of the factory alarm. I understand that the horn and lights flash when the alarm is tripped. At some point does the horn stop and the lights continue to flash? If so, how long are the lights supposed to flash on their own? On the way home from work I walked by my car, which was parked on the street and my hazards were flashing but the alarm wasn't sounding? I turned off the flahing lights with my remote.
