You would it , you still have a timed exits or instant set , or contact set depending on how everything is setup
I don't really know the panel well just entertainment for you while everyone is having tea break
Ah I get it now , I did usual didn't read the stuff proper
So it's code reset , does the software do it over the phone on this panel?
Meaning read code code sequence etc
The bell output is normally high and drops when tirggered so it could be same as saying negative applied
But if what your saying is a technical issue then it's weird as positive removed can mean it doesn't want to see ov either
But probably basic SIM diallers are negative applied for trigger as many diallers and should work on the belloutput for trigger
Try it perhaps hope you got plenty credit on the SIM
