900mhz transceiver

If you install 900mhz transceiver in gc2 panel is it no longer comparable with the 345mhz sensors etc?

The 900 Mhz Transceiver or 2GIG-XCVR2-345 is required in order to utilize the 2GIG-Go!Bridge, the 2GIG TS1 secondary panel as well as the Image Sensor. You will still have communication with 345MHz sensors after installing the 900Mhz transceiver.
