Nice internet nice i7
Point was get new alarm aswell
Normally one bell is wired to the other , so they must have wired and looped the tampers in the panel, perhaps parallel or they using a pair from one bell to the other
You need to figure out how it's wired and prove each cable is working , but if they are ok it's probably one of the bell boxes
You got ladders and get working
Loop out bell tamper in panel?
Loop bell tamper in one bell
Loop bell tamper in other bell
Determine which bell has incoming and loop the tamp there
Assuming one bell is not a dummy?
Should help you find out the problem but as you said above a few decades have gone by now
How did you make this post ? Dialup?
You could buy newer panel bell etc but with visonic you genert in same situation , batteries don't last long
If every 12months the price of battery is to much Rip it out as value of what your protecting might not be much
Ah ok , I never saw the config change on anpr , wouldn't that be only if the DVR itself has that anpr control
Just seemed as if the op NVR doesn't have all those facilities on the NVR to have changed the him , except obvious stuff like image settings etc
Dude question
Does the alarm set and unset
If you tap the windows does it set the alarm off ? (Don't break glass) try screw driver tapping on frame then lightly on glass near them
You still fit many ? I hate them lol but then I am a house basher I guess....
Dude I don't mean to be funny but you want full training
Goto Honeywell and get training or practice on the panel
Or go YouTube Honeywell have there own channel to teach you basics
Yes , never been serviced or tested correctly , probably lost its programming and you need a new alarm , probably costs as much as some smart phones people get
Scrap it , especially if you have no value on your property items and self
