Confused. According to the Qolsys supported z-wave devices, and this thread, the AeoTec siren model DSD56-ZWUS is compatible with the IQ panel. The issue, I can’t find any internet reference to DSD56-ZWUS?? Could this be the ZW080-A17?
Believe so, but the QZ2300-840 also listed is the same siren I believe. The model they list for the Aeotec version follows the cadence of the repeater model number. Aeotec unveiled their “G5” as a unified line-up so it wouldn’t surprise me if the model numbers were changed. Although you would expect a little bit of a trail online, like you I can’t find anything.
