Hi all, my first post here.
I have a Scantronic 9452 system.
One of the Alarm Panel Control Buttons has come off (Missing).

 

Ideally, I'd like to find a replacement button. 
My next option is to find Scantronic 9452 Alarm Panel then find an alarm installer to do the necessary work. 

 

What I would like to know is:
1) Where can I find/buy a Scantronic 9452 control panel button?
2) Where can I find/buy a Scantronic 9452 control panel?

 

Thanks in advance for any help!
