Yesterday I did a clean up of my HomeGenie disabling things I thought I no longer needed. After this I tested my Panic Alarm and discovered there were a few things required that I had left out. These may have been set by default with the initial install of HomeGenie.

Besides the Demo-Toggle Door having to be enabled the Virtual Modules Demo program must also be enabled. As well the Automation.Demo 2 "DoorSensor" need to have the options to "Use as security sensor" and "Also trigger when armed Home" checked. The Automation.Demo 2 "DoorSensor" has to be in the closed condition prior to arming the security widget or you will need to send 2 panic calls

Here's the command to arm the HG security system widget to armed home.

@russ thanks, I removed the deviceType from my json file and had Alexa rediscover and they do still dim. I edited my previous post.
It should be noted that using dim turns the device to that value. So if you turn a light on (100%) then say dim 20% it doesn't set the light level to 80 but instead sets the light level to 20.
At least that's the way it works for HG.
