I have a 2gig GC3, activated with Surety three years ago in March 2019. Recently, the panel alerts a few times a week. “Dual Path Communication Failure - Cellular”. When this happens I often do a radio test, and when I run the radio test I get “Cell Radio Module Status Not Detected”.
I tried removing battery and removing power to fully power cycle the panel. How do I figure out whats wrong - if Verizon’s LTE service has been reduced in my area, or does the “Not Detected” message mean my three year old cellular module is bad? Thanks!
