Looking at this link it looks like this can be done. you have wired up “OUT 4” to the IN 1 on the UBS, but this wont work as the Alarm panel outputs 12v on that circuit. I had a similar issue recently using a motion sensor that output 3.3v when active. to do this you need to use a transistor, i used a BC549C transistor,
overview is in this thread
so essentially apply the 12v from Out-4 to the base leg of the transistor and ground of the UBS to the Collector and IN-1 to the Emitter. ensure the SW-2 is set to OFF in your alarm panel dip switch, then you need to make sure that in the configuration block you set Parameter 3 as N.O (1) like below.
zwave.configurationV1.configurationSet(configurationValue: [1], parameterNumber: 3, size: 1).format()
this should mean that the circuit is treated as Normally Open so the Contact Sensor would be Open for Disarmed & closed for Armed when 12v is output to the base leg which will connect the Collector & Emitter.
you will also need to Connect the COM from the Alarm Circuit to the Negative of your UBS circuit
its certainly doable but its not as straight forward as the UBS will not read the 12v output
