Yeah 'go back to stores for parts' and pass it on to someone else!

lol ^

fixed...

Inside every revolutionary is a policeman...

I had a funny dealing, on the 'M' also that 'lid tamper' inc case and modules was always an eng reset event? Whilst of course you could set zone tamper to user... Not sure if that's right but had a play with an M600 last week prior to scrapping.

There, you answered your own question Nope, not a panel that's well liked - (except by norms BiL and whistles parents)

Hi there, welcome! Have moved your post to a new topic

Ah possibly, I know one replaced another

Ah but isn't that replaced by the YEND74?

Some say he took retirement, dissolusioned with the forum, it's posters, and the industry he once loved. There are others, who say he never left...

Well, I've heard that Knight use only EU or US made ones, I assume Elmdene buy 'locally' in China as they manufacture over there, and Ventcroft I can only guess must have bought a really sh1tty batch from god knows where. I have never had a door contact fail like that before, an RSD yes, although that wasn't welded shut that was random opening.

I don't think they make them any more (it was their only MC product) so I guess I wasn't the only one.

I tried the Ventcroft Premium Door Contact on a few jobs 2 years ago, they look nice on domestics, easier to fit than the Elmdene I was using at the time - feck me, back to nearly every single one, reed welded closed, Knight every time now.

Better take it up with the ICO then - it's very clearly laid out on the 'domestic CCTV' section of their website.

Any time public space is included, even if it is a small overlap i.e pavement in front of garden, the domestic total exemption no longer applies.

It will very soon, although have admitted enforcement will be few and far between at this stage.

As I have said before, this is a common and known fault with this panel. It will only be hours / days / weeks before it fails again either in the middle of the night or during a power fail, especially if the battery is knackered. It is likely only the live power on the panel that is currently sustaining the NVM, or as it current is VVM, Very Volatile Memory. At the very minimum a new battery and 24C16/M24C16-WBN6P DIP-8 Serial I²C Bus EEPROM is required.

I would add that it sounds very much to me like you need a new battery, too. Even if it was OK, if it has been drained pancake flat, it may never recover.

Yes it's a one wire I2C EEPROM chip, obsolete but freely available on the secondary market for a reasonable price.

No test required, NVM failures that presented like this were very common on this panel, even in its heyday, power fail or not - but often after a complete loss. I can only assume there was a design issue on this panel that meant the NVM IC was either overvoltage or written to far more than was really needed or recommended by the IC manf.

But in this case sounds like the old disappearing NVM issue. I think more likely the NVM has been dead for years but by fluke the panel has always had either mains or just enough battery until now....

No, newer keypads are square although if you are 100% comfortable with the whole DIY thing, an older 9330 LCD keypad would cover the exact same space (esp. if the existing keypad was a newer 9827) and work even with a brand new 9561PD or a 9571 9853 etc.... However you would almost certainly be buying that 2nd hand, although new unused ones do turn up on ebay from time to time. Our advice is always to get professional help / installers, although any DIY questions are welcome on our forums too.

Hang on, there is the NVM change to try first! This will require a complete reprogram though which is best left to a pro, and we can't give out engineer manuals I'm afraid. But to be quite honest, this is an old panel and a nice new LCD display such as on a 9651 or a Euro Mini etc... would be a huge improvement.

9800 or 9800+ if showing 'LB' I wonder if the power cut has cooked the NVM chip itself, a common fault at this age on the panel. Try a complete power cycle, mains first then battery, and let us know. Beware of mains voltage if not a trained alarm technician or electrician. But I would recommend replacement with a 9651, although new NVM chips are still available (despite their obsolescence within the wider IC industry)

Welcome and hello!
