Most panels now require an engineer for app registration
Then you have things like the Yale free app atthe moment.....
What other systems have free app? Risco have started charging , you can get selfmon for galaxy or the free gx app providing you got a fixed up and so on
Pyronix charge ? Or needs installer not sure
You going to use a separate panel linked to the texecom?
Or just use the texecom with alarm cable?
I got no idea by the way just asking if that matters before experts arrive here with there fire beams
