Paul P Posted February 11, 2014 Share Posted February 11, 2014 Also unless already replaced youll soon have trouble with the nvm (one of the chips inside). Why will the nvm fail on the panel out of curiosity? Is there an age problem with them?

norman Posted February 11, 2014 Share Posted February 11, 2014 They do fail but can be replaced easily and cheaply, same chip as the old digis take. Nothing is foolproof to a sufficiently talented fool.

breff Posted February 11, 2014 Share Posted February 11, 2014 The NVM stops taking programming changes eventually, something to do with write cycles The opinions I express are mine and are usually correct!

datadiffusion Posted February 11, 2014 Share Posted February 11, 2014 Its exactly that, mega old fashioned wire memory eeprom never really designed for multiple changes over a period of years. So, I've decided to take my work back underground.... to stop it falling into the wrong hands Link to comment https://www.thesecurityinstaller.co.uk/community/topic/36114-scantronic-9800/page/2/#findComment-368026 Share on other sites More sharing options...
Paul P Posted February 11, 2014 Share Posted February 11, 2014 As the log is NVM backed up I assume it wrights to it every set and unset?

datadiffusion Posted February 11, 2014 Share Posted February 11, 2014 Yes, I guess so, failure is unavoidable I think. My one in the garage at my parents old place was set and unset twice a day and failed about 8 years after the panel was new.

norman Posted February 11, 2014 Share Posted February 11, 2014 So, 8 years old then? Nothing is foolproof to a sufficiently talented fool.

datadiffusion Posted February 11, 2014 Share Posted February 11, 2014 Not quite, the reason I used that clumsy phrase was that it was ex the main house at about 4 years old, and usedmore heavily, ironically, on the garage.

ian.cant Posted February 11, 2014 Share Posted February 11, 2014 The 9800 was a panel designed in the early/mid 80's, why would you want to use something so outdated?
