Touch screen does not have sound coming from system. I was informed by comcast technician that a firmware was installed and then removed which disabled the speaker (it chirps low like a baby bird). In a two story home, this is not an effective alarm for security. WHEN ARE YOU GOING TO FIX THE SYSTEM OR EVEN NOTIFY CUSTOMERS? Had a technican work on system for three hours on one day and returned the next morning. Now I have a system that only chirps and is not effective at all. Repair / replace or refund!
