I have an older Viper 300 esp alarm in my car from years back and it works fine but lately whenever I start my car up the thing beeps 3 times for a total of about 5 times then it's fine. The beep is coming from the actual alarm unit and not the horn of the unit so I find it strange this is happening. I checked all the fuses and they seem fine and the alarm engages and disengages like it's supposed to. Any ideas?
I didn't install the alarm a professional installer did.
