I turned off my ADC cell radio on the 2GIG panel Q91(0), and then did a walk test (after I noticed my first floor motion detector (image sensor) was zeroed out for the MAC, and the battery status).
The IS went offline and was rendered completely nonfunctional which surprised me, as I expected to lose only the Image capture capability of the sensor, but have it still function as a normal PIR motion when the cell module was disabled (considering it is installed as 900mhz panel device, and programmed as a panel interior follower motion detector sensor).
In a nutshell, turning off the cell radio, turned off the PIR motion detector/Image sensor.
I was not aware that this 2nd gen PIR motion detector would be rendered inoperable and useless if the cellular communication/ADC backend connection is lost/disabled. I got rid of some of my PIR1 sensors when I “upgraded” to the 2GIG-IMAGE1, now I am thinking that may have been a mistake…
is this by design, or is this a bug?
