WS4965 not connecting to IQ2+

I am having problems connecting WS4965 to IQ2+.

Tried in both in tilt and in reed/door mode. I have 2 of these sensors and neither one of these works.

Says DSC Tri-Zone Wireless Contact WS4965 Ver A on the box

Ah, I guess this is because I have 319.5MHz panel and this DSC device is using 433 MHz.

Yes, if you have the 319.5mhz legacy radio then 433 sensors wouldn’t work. PowerG sensors work with all IQ Panel 2+ models.
