Third/Custom Arm Mode
My daughter and family left for a one week well earned vacation and her parents (My wife and I) said yes for their two cats to stay at our house. Her SS3 has entry, glass break and other types of sensors, but no motions. Ours has 9 motion sensors and 3 SA cameras with motions. Subtract the three rooms that is off limits to the cats and we now have six motion sensors and three cameras that I manually changed settings for home and away modes. Whew!
An added mode, "custom" would have allowed me to configure "Cat mode" next time they visit (which is in about six weeks).
