Does the “QS-7131-840 - Qolsys S-Line 16-Hardwired to 16-Wireless Zones Translator” work with the “QS9202-4208-840 - Qolsys IQ Control Panel 2 Plus (for DSC, PowerG, 433 MHz)”?
No, the Hardwire 16 converts wired to wireless on the 319.5 MHz frequency. This would not work with the DSC 433MHz version.
You could use the Resolution Products RE508X universal wired/wireless translator in this instance however. More information on that product can be found here.
