the inability to manage my own system would be a solid “yea never mind this isn’t what I wanted” and shipping the device back. it probally wouldn’t be a full refund but, that’s the cost for me making a mistake like that. I’ll be damned if in not going to be able to access my own alarm panel. I would be firmly against any setting not being in a user accessible location regardless if it’s a time thing.

Hopefully op had the tech enable all settings on the main panel cause that’s such a shitty money grabbing practice. Just lock the ability to change time behind a service code on the main panel. incorrect code = alarm is triggered.
