It appears you can not use the emergency button in test mode. I can not find any info what happens when you press it monitoring mode.
Does it set off the alarm in the hub? If you have your unit disarmed but need to press the button, is the emergency button still active? Is there a way to test this feature without triggering a response?
Since this button sends an immediate emergency response alarm there needs to be some clear guidance how to use this feature properly.
