I’m sorry for the frustrating experience.
In my opinion, the 345 MHz sensors were probably never working with the new panel. Even though they showed as OK initially, it just took some time before the panel realized they aren’t working and started to complain.
I’ve sent a few troubleshooting commands to your panel but almost all the 345 MHz sensors still show malfunction. One of them (MB front window) currently shows Closed but I’m not sure that will last. If you open and close that window does the panel see the status change?
There are a few things we can try.
First, let’s update to the latest firmware.
If that doesn’t help, could you move one of the sensors close (about 5-10ft) from the panel and see whether it starts communicating? Either open & close or tamper it when near by. That wouldn’t solve the problem but it might tell us whether the 345 MHz card is “working” but not receiving signals well enough, or not working at all.
If that doesn’t work, then let’s try powering down the panel, disconnecting wall power and the battery, waiting a few minutes, then reconnecting battery, reconnecting wall power, and letting it boot back up.
If that doesn’t help then we would need to wait until Tuesday and get Qolsys to help us. I suspect they may have us power down, remove the daughter card, re-seat it, and power back up.
If that doesn’t help then I suspect we would need to just send you a new panel under warranty (assuming you bought the IQ Panel 4 from Surety) as there is probably something wrong with the 345 MHz daughter card, even though the diagnostics test passed.
