The factory security system is silent. If the bike is leaned, bumped, moved, etc without turning off the security system then the turn signals will flash and the engine won't start. You can turn it off with the remote control or by entering your "secret code" via the turn signal controls.

Harley sells (as do other companies) an audible siren or pager system that plugs into the factory security system if want an audible alarm. Install is 10 minutes for the audible siren...
