How can I get the driver to automatically go to the security page when the entry delay is activated?

This is currently not possible with this driver and it is a Crestron Home limitation. Popping up the security page is only possible if the driver uses keypad emulation. This driver does not utilize keypad emulation because the Elk panel does not support keypad emulation. You may file a feature request with Crestron if you want this CH behavior to change.
