Okay, here we go again. I was brave & rode the bike to work today, (cold this morning, brrr) so I called the dealership close to the office and asked them if they could take a look at it. I had talked to them several times before and they said to drop it off. We hook up the digital tech, and everything looked good. So they called HD and told them my story. The guy there explained that some sirens do not chirp. They will have the same part number, but some where the may be a letter to designate the generation. He also said that it would be very odd if it was a defective TSSM or siren, that the 'chirp' would be the only thing affected. They also asked him about turning the chirp off, which they seem to get more requests for, and he also said that not all sirens are programmable. So, you may have a siren that chirps and you cannot turn the chirp off. I am satisfied that my alarm system is working properly so this project is done! Thanks for all the help!
