does it just stop working? does the loss of power just set the alarm off ? that would make my neighbors and cat nuts ;-O
The battery in the system's touchscreen should provide enough power for 8 hours if your home's power should go out. It also uses a cellular backup, since in this scenario, your Internet services would likely be down as well. If you experience power outages that usually last more than 8 hours, you might consider purchasing a unterruptable power supply (UPS) to use with your system.
Also is there any way to set up two alarm codes for instance one for a pet sitter?
You can add additional alarm codes for a pet sitter. There's some good information here that can help you add additional codes to your system - http://customer.xfinity.com/help-and-support/home-security/manage-user-codes/
