LehighLuke,
Your informatin is correct. However there is a serious bug in the system when using "Interior Follower Arm Night". The bug is that all the motion detectors programmed as Interior Follower Arm Night have no delay and must be triggered before setting the alarm. If they are not triggered prior to setting the alarm, they will fire off an alarm as you are walking through any room with one of these detectors as you are on your way to your bedroom. Then you have to turn off the alarm, reset it and get to your room within 3 minutes. It is a major annoyance that would not occur with any system from any other real (i.e. major alarm) company.
Here is an example. I have two detectors at opposite ends of the house set as Interior Follower Arm Night. One in the Living room, one in the Family room. My kitchen is inbetween the LR and FR and that is where my Xfinity control panel resides. After setting the alarm I need to walk through either the LR or FM to get to the bedrooms. If I am watching TV in the FR for some period of time, get up to go to bed, enter the kitchen, arm the alarm and walk through the LR on my way to the bedroom, the LR motion detector fires off an alarm. There is no delay. Once the LR detector fires, it has 3 minutes until it resets. In that 3 minutes I can set the alarm, walk to my bedroom and then the system works as intended.
In the example above, when I leave the FR on my way to the kitchen, the FR detector is triggered before I get to the kitchen so its 3 minute reset window is counting, but because I have not walked through the LR, its motion detector is going to send an alert to the control panel as soon as I enter that room. The control panel treats it as an alarm as soon as I set the system into Arm Night.
Here is what I have to do to work around the problem. 1. make sure I move in front of both the LR and FR detectors and see the red light on each one before I go into the kitchen to set the alarm. 2. Then I have three minutes to set the alarm, leave the kitchen and make it to my bedroom.
This should be a simple programming fix to make the console ignore alarms from all motion detectors when setting the system to Arm Night. In other words, Xfinity needs to add a delay to the system when setting Arm Night mode.
The Interior Delay Arm Night might work when setting the alarm, because it does have a delay, but I don't want those detectors to delay at night when my family is in bed. The Interior Follower Arm Night is a prefered method but it also needs a delay when setting.
We have been living with this kludge for 6 months now and I'm writing this note so that hopefully someone at Xfinity will read it and download a patch to the console on the next firmware update.
