    Scantronic 9800 house alarm Cooper 9651 replacement

    Hi Handymanjo/all, the Odyssey 4E bell box arrived - with no manual. I tried looking online, and I think I know what to do, but it would be great if you could confirm. 1. Wall mounting. Can I use the 4 corner cut-outs indicated in the attached image to mount to the wall? With the bottom left...

    Scantronic 9800 house alarm Cooper 9651 replacement

    Thanks (again!) Handymanjo - I don't suppose I'll know for sure until I open up the old bell box. I had a chat with the lady's son. He's had a quick online look and ordered the Oydssey 4E - I hope this meets with people's approval. I'm sure I'll be back in touch once it's arrived and I've had...

    Scantronic 9800 house alarm Cooper 9651 replacement

    Actually, Handymanjo (or anybody else), any idea why there are two wires currently going to '12V' from the external alarm bell box (green and red in the above diagram)? I've not opened up the external bell box and I don't know the make/manufacturer, I was just wondering if bell boxes always just...

    Thanks for taking the time to review and for your comments, Handymanjo. Good to get your take on things and the two points you confirmed were the ones I was most unsure about. The lady's son has also asked if I could replace the external sounder whilst I'm at it so I may well be back to bother...

    Scantronic 9800 house alarm Cooper 9651 replacement

    Hi all, me again....sorry! I've been doing a bit of reading wrt the above topic (i.e. swapping an old 9800 system for a new 9651 system). I've opened up the lady's old system and tried to captured everything in the below image 'Alarm 9800 Old'. I've then tried to map out the new system...

    Scantronic 9800 house alarm Cooper 9651 replacement

    Thanks again, Sparkymarka. TBH, I read your response twice and I still don't understand so I appreciate this swap may be beyond me. But, in the spirit of learning, what are the advantages (disadvantages) of global tamper Vs resistors in each device? From my naive perspective a 'global tamper'...

    Scantronic 9800 house alarm Cooper 9651 replacement

    Hi Sparkymarka, thanks for your reply. I'm pretty sure it's the 9651 as the son told me he bought it a 'couple of years ago' with the intention of replacing it but never did and, since then, moved away without replacing it. I'm really sorry, but you slightly lost me with the 'end of line' (?)...

    Scantronic 9800 house alarm Cooper 9651 replacement

    Hi all, I hope and trust you’re well during these difficult times. An elderly neighbour has an old Scantronic 9800 alarm which, due to worn digits on the keypad, has probably had its day. Her son has done a bit of research and ordered a Cooper/Scantronic 9651 system as a replacement – he...
