Yesterday I swapped the iq 2+ for the iq 4. I had to input each shock sensor manually using their s/n because unlike the recessed d/w sensors, they would not pair to panel by removing the case or tampering. I noticed that after pairing them their status on the panel showed as "not networked. This was an easy fix because after trial and error I seemingly had to tamper them after pairing in order to be networked and functioning normally.
The issue I now have is that the PowerG smoke detector that I had, which worked completely well before the swap now shows “failure” on the powerg test from the panel. Before this status it had the infamous “not networked” status. I can’t seem to figure out why it isn’t working. Everything was fine when it was on the iq 2. Like the shock sensors mentioned above, the smoke also did not want to pair to panel by tampering it. So I had to use the device id/sn to manually add it to panel.
