Yep could also be faulty battery dragging the system voltage down, especially if not serviced. If so power supply will need checking for charging rate before battery replacement.

Sounds like too much current for most panels, would need to do standby and load current checks to make sure the battery and power supply is suitable. That Veritas sounds very overloaded.

Mains failure and it's running on battery. Maybe a fuse blown inside or circuit breaker tripped. Eventually the battery will die and trigger the external sounder.

Completely different panel and power supply setup. Premier will be a fair bit more in depth to program. A plastic cab will always yellow slightly with age but not go brown in the top left like some Veritas do. Normally that's a sign that the power supply has been heavily loaded, should do current checks. The Metal cab has a larger power supply and battery capacity, if that's a concern.

Switch mode power supplies and the regulator is off the board so will not be the same.

Yuasa are a good brand NP7-12 most likely

Yes, you could say they should have someone available much sooner but we don't know the full story. If this is non-contract and they have contract work booked that would obviously get priority. It's also self-inflicted you were told it was going to cause an issue and did it again, so I can understand it being considered less priority if busy.

The installation company and their procedures all sound perfectly reasonable. Vibration devices need to be calibrated if any changes are made to the mountings or frame. If you are paying a considerable amount more because of the companies distance away (unusual they would only normally charge for on site time); find a closer company but they will have similar procedures. I don't know Pryonix kit too well but most manufacturers with an app require an registered installer account and annual maintenance agreement to keep it active.

Diagnose and repair the tamper fault?

I've had a couple of those, only the entry door was connected properly.

I have known it to be used as leverage to lower the asking price. It sounds like unmaintained skip fodder TBH.

Those probably don't have a license, Technistore does... it's the main part of business like I said above. Technistore is included by the manufacturers, not made by them for complying.

Congratulations for downloading software without license...

It's proprietary, this software is one of the main assets to the company; unlike other product manufacturers you mention. Use another option or ask the ARC to set it up while your on the phone. If you have an issue with this being incorrect as a company, include it as part of RMV procedures you'll have majority sorted in 6 months.

No alarm component I know has 4x C batteries, that is most likely a doorbell.

Removing the hold off voltage should trigger the bell so best to replace the whole unit.

Yes, and yes as a temporary fix. It's down to if there will be further damage to the wiring in the near future. Something could be crushed or being chewed at for example. Also consider that you need 5 cores minimum, so you will have to cross check when pairing your cores. If it's the wiring and the bell and as important it's battery are in good working condition; there is no need to replace. When I say cross checking multiple pairs but also open circuit between everything too.

So? AG6 DIY and sparkie favourite... junk but available and popular. Everyone will have their own favourite panel and bell. If you have a sample size of 1 and it works for 10 years what's the issue...

Linking the TR to 0v will disable the bell tamper loop (on most panels) to rule out the panel being an issue, which is unlikely but possible. Not too keen on Deltabell. Any "wired SAB external sounder" should do, many manufacturers from CQR, Honeywell, Texecom, Pyronix. Scantronic/Eaton have one which is most likely to have wiring diagram for 9853 if you need. They may come as two pieces lid and backplate, companies would have the lid screen printed in bulk so they often come separate. Strobe flash is high voltage don't go poking it. Electrocution and working at height not a good combination.

There is something wrong with the bell tamper circuit, so the wiring needs testing with a meter or the bell needs testing and maybe replacing. As it doesn't seem intermittent it should be relatively easy for someone knowledgable to find and repair.

My percentages where facts not statistics, where is the source for this and how are they collated... No-one is going to admit to being a professional burglar, even serial burglars know how to play the game so it looks unmeditated to do less time. Saying a GSM speech dialler is the "same signals" as a Dualcom unit is just bull! Your saying your talking from experience, what experience; compared to the rest of the trade members in the forum?

What use is a security product that works 99% of the time in general use, but 0% of the time if attacked or jammed. I suppose they still fit doors with cheap euro cylinders so there is a market for rubbish...

Thanks for your additional comment a year later. Lets just say the remark wasn't solely about the plug top... A plug top could actually conform, provided it was secured from accidental disconnection. Also who knows what qualifications, competence or other help the non-trade that post here have. It's in the DIY section, they may want to wire it in wet string via a bathroom.... Being trade we explain how it should be, any one with basic DIY skills can throw wireless kit on the wall wrong.

It will probably be fine, but they recommend to be installed within 15 months of manufacturer.

As far as I am aware they are still Year Month Day Batch, yes
