I use mine with HSM to arm/disarm. I also use it to chime when the front door is opened. I also am using the stock driver. I have 5 of them. I turned the volume down on some as they play things such as disarmed out of sequence, but I like them better then the Iris V2/V3 devices.
I have an iris I'm going to plan on using for emergency access. Enter the passcode to "deactivate" the keypad, and it will allow access into the house in case someone forgot their key
If you have a contact sensor paired you should be able to test HSM, otherwise you could create a virtual sensor to test. I actually did this when I first received my C7 as I had originally planned to wait for the Protection Service to migrate, but wanted to play with the new Keypads.
In that case you can always create a virtual contact sensor if you want to test out the keypad functionality now, or can wait until you migrate over some sensors.
