The dinosaurs died out, alarm monkeys are now the rare species...

Poor installation of the cable doesn't mean that it wasn't tested tho. There is a big difference between wiring eight core or flex straight off the back of a socket (both I have seen) and a well installed 3A spur without a MWC IMO.

You'd be amazed what creatures get through a 20mm cable opening on the back of the cab.

A fault on whatever is attached to zone 3. Doubt a manual would help you diagnose.

Draytek Vigor what model? All the SOHO Draytek stuff has good diagnostic features for stuff like that. Start with checking the DNS

Glad i don't see many of them Online SLA's anymore, swap on sight.

No company should be blindly taking over systems by defaulting codes alone.

Internal sounder tamper is the most likely. System needs a full service, replace any batteries possibly the external sounder, check all the voltages etc If it's never been looked at since installation then the battery charging circuit could have failed causing intermittent randomness. Alarms are generally only reliable if you install them well and service them regularly.

Nice to see Honeywell are happy to talk you through defaulting it.

The installer will keep there own engineers code. You should contact them.

Those seem to be the popular ones at the moment rebranded by a good few places. Lots of different models of the same thing due to the optional features so make sure it's got all the features you need. You can buy them cheaper direct from China but consider that you may struggle with any returns if faulty down the road compared with buying from a wholesaler. Seen a few listed as for parts and not working on ebay in the past, so I would be wanting to consider warranty period.

Pen Test Partners have found another vulnerability, this time in car security apps. https://www.bbc.co.uk/news/technology-47485731 Another example of consumer driven rubbish being attached to the internet leaving people vulnerable to attack.

They are designed to drive two 16ohm speakers in parallel so you can work out the impedance from that

Labelled Volume?

I imagine it's actually the speaker volume you need to lower. Pot on the main control board.

I would suggest you try to contact the company that installed the system. If the system isn't under maintenance then it would be a good idea to get it looked at anyway if it hasn't been serviced in a while. The system sound like it has been activated and if your not sure why then it would be a good idea to get it looked at as above. SD1 is a dialler not the main system keypad.

That would only be for equipment fitted to pass building control, so new builds etc. Your fitting would be 113 l/W anyway.

I thought bat was your chosen weapon for printer slaying? EU phase out of incandescent has now been followed by halogens, doesn't have anything to do with wattage AFAIK.

150 watt limit by who? What's the application? I have a 200W LED low bay kicking around somewhere that is designed for commercial. All I need is a lens and a dead bat to summon Mr H...

Use the code you want to change then you can't mess anything up. Be something like Change Code > Yes. Manual is in downloads. https://www.thesecurityinstaller.co.uk/community/files/file/414-gardtec-800-series-user-guide/

Doubt you would have the same view if it set fire to something, highly possible if something failed. Input is AC so no positive or negative... Alarm cable would make sense for everything on ELV side, unless you have data transmitted then you will likely need a TP cable. PSU's don't "emit" 3A they "supply". Each core of good quality alarm cable as a max current of 1A @ <50V max. Therefore, I would be using all the wires of an 8 core, if you are crazy and plan to pull a 3A load from this cheap supply for whatever reason. I'd think an extra 50 quid or so would have got something safe, that comes with a understandable manual? Although the text on the terminals seems fairly straight forward. I reckon the cheapest option would have been a mechanical solution on the cupboard.

So is MSN

Looks pretty unsafe to me and you can't even see what rubbish is inside....

I do know it's DIY, if you know how to work on one then that's fine maybe you can answer the questions, I am just saying I doubt anyone here has fitted one and it's not easy to work out unless you are in front of the thing. When I go looking for professional advise I don't expect people to guess when they advise me. The picture of the door contact is a bit too close to answer the previous question regarding fitment.
