i think that's the one my mom has on her van. idk if it's the brain or a crappy install but it chirps at random times too. usally after you arm it chirps once like normal then a couple seconds later it chirps like 4 times in a row. it does this occasionally when the car's disarmed too...

idk i don't care for that alarm at all and i don't think it'll do very much to deter anyone. but it's on dodge caravan so i don't think anyone wants it anyways. :P

i have a viper on my car and it kicks ass. :thumbsup
