Complements of the season one and all, Following my previous threads relating to a noise' from the external sounder when the mains is active, I have decided to replace the Accenta Gen4 Mini panel with a 'new' one from an eBay seller. it is of course, old and no longer made, but it is unused...

A new, replacement sounder did not cure the issue so I have bought another, albeit old(ish) stock but new panel and will fit in due course. Will post he result when installed.

That is my thought also, so my non-technical conclusion is that it would be best to buy a replacement panel. Have found a new, albeit from that era panel at a price that is certainly less than engaging an engineer who may tell me, you need a new panel.

You are absolutely correct but that is not a very helpful comment. However, I did install this alarm when I built the house fifteen years ago and it has been working just fine until recently when, I set the RKP and the external sounder started to make the 'noise.' Assuming it was a battery...

Did a factory reset but that has not stopped the beeping when the mains is on. Also checked the AC voltage with power off and on. Meter on AC, pos probe to12v DC, neg to mains earth and check with mains off and on. In the photo, the mains earth is arrowed; the AC reading with mains off at...

Since starting this endeavour we have not had a working alarm and I really don't know where to go next. All I know for certain is, a new external sounder has not solved the issue so presumably, it is nothing to do with the sounder. But the panel works just fine on batteries alone, the warning...

We have mains water pressure throughout the house but two of the hot water taps are blasting air and water. Don't know where the air is coming from and it does clear, but like the Terminator, it does return. The house water pressure is about (or less than) 3 bar. Checked the expansion tank to...

What ho one and all, Owing to a minor hot water issue, I turned off the mains and depressurised the system before checking the expansion tank pressure. The system is mains feed with a PRV set to around 3 bar. The expansion tank reading was 0.75 bar. Assuming that the tank should be around 3...

Used to live in Hong Kong and yes, the bamboo scaffolding is amazing. But they do use cross bracing. One tie, in the industrial building where I worked, it was necessary to do some repairs between an adjacent building, about the 14th floor. What do they do? Cut some bamboo around one foot...

What ho one and all, Looks like an A&E visit waiting to happen!! What! Not even any cross bracing!

Not really as I could not see a piezo component. The only sound producing item is the sounder itself which I think is a large piezo.

Managed to find an unused Reson 8 bell box, on eBay. The 6v battery only measures 4.4v so installed the 6v battery I bought as a replacement Wish I could report that everything is fine, but no. The same 'kinda' warning beep happens. Did some checking and found that the entire system appears...

Excellent idea. Will give that t try. Thanks

Pretty much the same price as they all appear to be; £19.33. Like everything, Made in China. I tested and it is reading 6v, but so is the old one. The sounder beeping is quite loud, somewhat an electronic warning beep and is around two per second. Research does indicate that the sounder is...

I have fitted a new 6v NiMh battery and replaced the panel 12v battery. Everything looks good until I reconnect the panel mains power when the sounder, rather than the alarm sound, emits a loud beep, beep, beep. It is not as ear-piercing as the alarm, but certainly annoyingly loud as if it is a...

Reson 8. Pretty sure it will fit. What is the benefit of 7.2v verses the original 6v?

What ho one and all, Want to replace the 6v 330mAh Ni-MH back-up battery. The one I have removed has the following markings - 280H5A1H When I Google search for a similar, I have found 7.2v Hi-MH GP320BVA6...

Again, many thanks. Not worried about having to replace if necessary as I installed the alarm myself when I built the house. New 12v battery reading 12.87v unconnected 12.7v when connected but mains off 12.6v with mains on However, still getting a loud pulsing beeping from the sounder but...

Thank you for your advice. The panel is giving around 12.6v to the battery. Probably not significant but the sounder is also working so presumably, that is taking some power from the reading? OK, battery alone around 7.5v Battery connected but main off, around 4.4v Battery connected with...

Just watched a YouTube vid. Disconnected battery is giving around 6v and when connected to the power, around 7.5v. Does this imply the charging circuit is faulty? With the panel powered, the sounder (Ni-Cad removed) is either doing its alarm thing or some kind of lower volume warning noise...
