Can't add sensors - Installation menu missing

I’m trying to add new sensors and it appears the Installation menu is missing on my IQ Panel 2.

Is this due to the device being active with Is there a test mode the device needs to be put into, or how do I go about adding sensors?

Solved. Had to enter installer code instead of master code.

Yes, the installer code is required to access sensor programming, as well as other panel programming features.
