Yep that’s exactly right
I fail to see a difference between inching and momentary In this case.
I’ve done this and connected it to my Konnected board to notify HA if my garage is armed. I’ve partitioned my alarm so it’s like it’s 2 alarms, 1 for the house and the other for the garage. they work independently and are called zone # area. So my house is zone 1 area and the garage is zone 2 area. If you you haven’t selected any Zone inputs (like your sensors, keyswitch etc) to a zone area # then it’ll be the defult zone area 1.
Choose a free output or 1 you’re wiling to go without. I used output 2 as I haven’t got a smoke detector/fire integrated with the alarm.
So on the output programing you would change the 1st event code from 2 to 5 and the 2nd event code from 7 to 6.
So that output would close when (Zone) Area 1 is armed.
What are you planning on connecting the output to?
