Car Alarms: Car alarm beeps horn upon starting car., rapid succession, beeps

Question
Hello- I am desperately trying to solve this problem and you are my last hope!  I recently purchased a vehicle with an after market alarm, Executive brand (made by Omega ?).  When I purchased the (used) vehicle it came with one remote which worked, and when starting the car no alarm noise was made.  I then purchased two new identical remotes off ebay (same brand and same FCC #) and programmed them by cycling the ignition 5 times.  All 3 remotes now work, except that when starting the car with ANY of the 3 remotes, the horn beeps about 5 or 6 times in short, rapid succession.  It is extremely annoying and I have tried reprogramming the remotes to get it to stop but can not stop it.  Please advise.  Thank you so very much in advance for any advice you can give!

Answer
The best thing here is
to write to my OMEGA Alarm (CARALARM.COM)
technician at scadss@tmail.com and see if
he can assist you with this issue.

I unfortunately don't know the
system you are working with to advise
you properly on it's functions,
features or trouble shooting
information. Better to check with a tech
that might.

Good luck there.
