You need at least four cores for an SCB/SAB. If you do have four you will need to check they work.

I don't understand why you would make a system less sensitive while the site is unoccupied. As for using the fire sounders for security, I just wouldn't.

Hi, quite a long first post. Am I missing something here, why is the intruder triggering the fire alarm? Forget all the technical side for now, what does the consultant want/expect to achieve by linking the systems?

Good to know.

Chav sign with no planning permission who'd do a thing like that?

Fully agree about anything would be better than nothing. It's useful to have all the information available, let the OP decide on the risk.

There are other caveats with using the intruder alarm, standby time being one of them if I recall correctly.

You shouldn't have two batteries on Texecom controls any more only the PSU's. Splitting battery output without separate monitoring doesn't conform Texe have a battery splitter but only works on pre-Elite. Will have to look at 10Ah batteries maybe handy on some jobs. Failure rate on 17Ah's unacceptable. I believe they accumulate lead sulfate quickly when charged on an alarm panel, I have recovered a few failures (IBT read ~7Ah) with a motorcycle battery conditioner, they're now in a UPS.

Surely they both have specifications of dBA@ 1m? An current consumption

We didn't know what the property was from the OP. Yes, I have serviced many a fire alarm in domestic properties, however all have been detached properties of various sizes. Mr. H hits the nail on the head as usual, should really be mains interlinked. Mains interlinked would be installed with 3C&E mains cable. Would use Alarmsense over Twinflex, DD.

When I say "working" I don't mean the LED's, do they operate correctly irrespective of the LED.

Are they working at the control panel? The dim one maybe the plastic LED prism missing from the cover? Not used them in a while prefer other sensors.

Or a fire alarm system.

A quick look at the list and there's more than I would put on one panel, would have used a power supply expander. Do you have expander units or is everything crammed on that panel. You also appear to have no external sounder or have some of the list missing. As for your question it's not as simple as listing the parts, we would need to know standby and alarm current for all the components or the system. This is an important step to commissioning the panel upon completion.

No bad press? https://ipvm.com/reports/the-hikvision-hacking-scandal Available everywhere, ADI, DVS, Norbain, Maplin...

Someone sent the pilot for one long stand?

Agreed, also not helped by the fact much of that 90% is poorly installed or not FFP.

Hmm, never seen an onboard one. Not terrible panels, but not great either.

Fitted much pet tolerant stuff over the years and the only PIR's I am confident in are the Bosch one's above. If using anything else I would use perimeter protection. Double knock is not an appropriate method of reducing false alarms, full stop.

"British dance-rock quintet"... er no ta. More appropriate me thinks.

Your welcome.

I am too young but you could get away with driving any old chassis on trade plates. Can't imagine you'd get away with that sort of thing now.

I would usually say Leyland but I imagine many wouldn't know where that was. Dennis kid myself.

Back EMF is the word your looking for.
