Have you check there is actually mains getting to the panel? Its unusual for a mains fuse to blow unless there was a surge when you powered up

I got good images of someone dumping a stolen car outside my old house, and caught neighbors hitting my car with theirs twice. At the old shop when those kids smashed our Window 8 years ago we identified them caught them and prosecuted them, all from the CCTV. It can be done. At the new business premises we caught a fly tipper who dumped a load of asbestos on the estate, we captured the footage of a bloke getting run over. Pikeys stealing a load of plastic pallets (ANPR) and more recently the catalytic converter thieves ANPR. The fly tipper successfully prosecuted the pikeys could not be traced, nor the cat thieves, vehicles not registered to them. We have numerous successful CCTV captures for customers CCTV set up properly works.

Iirc there is a resistor or link required at the bell

Until something happens and the recording is no good

The problem is Hik and Dahua are no longer shit, not when all things are considered. Most of the people who fit it seem to be, this is why fixed wide angle lenses are so popular. If you ask the average engineer what back focusing is or BLC or HLC he could not tell you. They also think that 4k is more important than anything else such as FPS. Anyone can install CCTV and make pretty pictures on a screen very few can make good recordings of crimes.

many people think Hik is the best, but can only plug and play

You just need to meter the blue and white wires to find out which is positive this wire doesnt need connecting to the bell just the negative trigger

what does it say on the bell?

Exactly unless you have lost Police response and have to upgrade because you lost police response you can keep it 4737

QFA, But DIY is not likely to need the same protection ............... is it?

I saw that a few days ago, it reminds me of someone who thought (probably still thinks) that he knows better than anyone else.

You may as well of said my car wont start can you tell me how to fix it? or how long is this piece of string? You could take a three year apprenticeship and become an alarm engineer, or you could call an alarm engineer out. But there is no magic sequence of buttons we can tell you to press that will tell us whats wrong, you need a multimeter and the knowledge of how to use it

Wasn't knocking the panel, just stating the facts

Id say closer to 20 years old, there wont be anything that will work with your existing wireless detection hard wired will be okay

Electricians are not the same as alarm engineers, its like asking a dentist to remove your tonsils.

QFA these things stop working for a number of reasons, but its not normally because you changed the number unless you misspelt it

Any proper alarm company will be able to sort it, not sure what sort of engineer you got out but tamper is a basic thing with all alarm panels

Unlikely DSC is no longer sold in the UK , and even when it was it wasn't the most popular

Not necessarily the detector, it may be that its not programmed correctly, it may be that its linked out in the panel, or a cable fault.

I heard the Honeywell were stopping everything apart from their biggest panels.

I would say that was DIY installed, is there a fused spur? IR detectors work better in corners rather than in the centre of a room especially quads. Also I would not waste money on the cheapest detectors you can find, Optex RX40 would be my choice. There is no point to alarm system that keeps crying wolf. Im not a fan of Pyronix either but I couldn't recommend any panel available to the DIY market

More or less correct well done. If your replacing the system completely I would suggest you go for hard wired as the wiring is all in place. If you need to add additional detection but have no way of wiring to the new locations then go for a hybrid panel so that you still make use of the hard wire. Wireless systems are fantastic very reliable compared to what they used to be, but there is no point in adding battery powered detection if you have cables run already, your just adding another thing that may go wrong, the batteries will always run out at the most inconvenient time.

Yeah but they are not allowed to watch youtube in China so its fine

Two different brands, im guessing that your old system was hard wired and it was replaced with wireless, who knows why, some people do daft things I suppose

in a nutshell yes, just buy new detectors from the same manufacturer, personally though I would recommend returning it and buying a proper system or a big dog
