I installed a Scantronic 500r+ wireless control panel + PIR's probably 15 to 20 years ago. I have a AG6 external bell + strobe unit hard wired.
The system has worked reliably since day one then about a month ago the bell + strobe unit started making more frequent cheeping noises (like very loud magpies). I tried to solve the problem by trying various tests but finally figured out that the AG6 tamper switch had become faulty. I bought a replacement Honeywell AG6 from Amazon and installed - easy, until 2 days later the Scantronic control panel has stated making a low droning noise from the loudspeaker. There is no 'fault' registered in the system but I have had to temporarily disable the whole system by opening the control panel door.
It seems too much like a coincidence that I replace the AG6 bell + strobe and very soon after the control unit speaker starts acting up - as if its picking up a feedback signal from somewhere.
I've tried Cooper Scantronic but you need to get past the registered installer code system ........
I would appreciate any suggestions.
Many thanks
