Either way get rid of that junk and if you have fault you will have to fix it
So Honeywell flex might do the job for DIY fix , I assume you know how to programme an alarm? Otherwise local installer maybe your best option
You may end up having to open some detectors , but they probably as old as the panel and plastics can break
If your not on tight budget then get all new sensors aswell
If your not on tight budget and still want to reduce cost , then probably what your protecting isn't worth it anyway , so just scrap and leave it on the wall and have no alarm
Otherwise wireless DIY pyronix enforcer will do you....
Not always the case
You trust him to install it so trust him to maintain it, mostly they do this to help you in future
However if it's just a user password change it no problem and make sure you know what you set it at , make sure you do all the bits like security questions fail safe , maybe make another user password and so on
In anycase it's not like camera is pointing at your fridge....
Dude start again
Zone 1&2 resistor legs touching
Make all zones unused the ones you don't need
But before that remove the Rio power it off , restart panel , reconnect Rio , add Rio
If your here I don't think you will be making jack , just an honest opinion no offence
As above China will do it all for you , but better to learn mandarin first
I have a broken set , they are no good for to much use outdoor , odd occasional job , I think mine cost about £140 ten years ago , it did its job for the job I needed it for, and that job paid for them anyway i uesed it handful of times
They haven't changed much , if I need another I will price it in on the job I need it for and have it new each time lol
