2gig E Series Sensors on IQ IQ Panel 4 345 Mhz compatible?

Could I use the same sensors for a 2gig E Series system on IQ Panel 4?

No, 2GIG E-series encrypted 345Mhz sensors are not compatible.

Standard 345Mhz 2GIG sensors (not E-series) would be compatible with the 345Mhz version of the IQ Panel 4
