Add a speaker to the base station?

As of right now, there is no official way to do it, however, if you use a google site search, some customers have a hacked solution. For my SS3 system, as it was with my SS2 system, I have it configured to no lights, no prompts, no noise, period.  The delay for home is set to 0 and for away, I called and cranked entry down to 20 seconds. Add that the base is quiet, very unlikely an intruder would find it before sending a signal to monitoring company.
