I have a 2gig system.
I currently am having my windows redone and there is space to the outside of my house as the windows are out… I currently have 2Gig thin window contacts.
These contacts have the ability to use an external input. I think when you use them normally you use loop 1, when you use the external input you use loop 2.
Could I use loop 2 and an external magnet on the loop 2 on my existing contacts so that my loop one is functional for the window and loop 2 is functional at the same time so that I can put contacts on the screen doors causing them to go off if someone should remove them?
Or would I have to buy 2 sensors per screened window?
If I can do it with 1 sensor, where can I buy the external input wires along with the magnets (I assume I need a set) as I have thrown away all those wires when I first installed my system years ago.
I am also open to anyone with suggestions on a better way to arm the screens knowing they are subject to outdoor weather.
