I'd agree with ChrisH. Connecting the White and yellow terminals together should either lock or unlock the lock. Most locks will unlock when you break this connection, as this is safest. Your best bet is to power the lock and then briefly connect these two terminals together and see what happens. If this works, then you will want to wire these two terminals to the Com and NC terminals on the relay 1 port on your controller. There may already be a link from NC to 0v on the Paxton controller and this should be removed. If that works backwards, then connect the wire from NC on the lock to NO on the controller. You will also need to work out if this is a fire door that's released with a fire alarm relay, and if you should have a green break-glass on this door.

We've had similar issues on other HP computers What fixed it for us was changing from the Microsoft driver to the intel driver in device manager > Update driver > Browse my PC > Let me Pick

We've used David Fitch Services before. Stage Electrics are also good. Whitelight do this sort of thing as well. https://www.davidfitchservices.com/

The one bit that worries me about giving advice on a public forum about some types of device not needing a PAT test is that you don't know the condition or location of equipment in other schools. There are plenty of bits of kit that shouldn't be subject to an insulation or earth bond test, but how would you feel about a 30 year old UPS with knackered batteries, or a cheap Chinese import that doesn't meet the appropriate standards? What if its in the back of an IT suite or office or mice have been at the internal wiring? There's so much possible variation here - one size doesn't fit all. If a UPS is hardwired, then it perhaps should be tested along with the fixed/installed wiring - at least as far as a visual inspection of wiring and checking for overloads, battery condition etc. Risk assessment needs to be specific to the school in question, not just copied and pasted from somewhere else. The PAT/electrical testing process is about far more than just the checks with your PAT test box. How are you sure an item is safe to use if its not tested/inspected? Ultimately, that's the legal requirement.

Liveregister has been really good for us. Very few, if any, problems. The company has always been helpful. We ended up supplying our own till hardware due to bad experiences with a previous company - often with these systems, the tills provided are really expensive and massively under-powered. We wanted to have control over this side of things. We ended up using some all-in-one touch screens from VeryPC and putting them on Ergotron mounts - although the last unit we had didn't need this stand.

PAT testing isn't really a yes or no thing. You need to look at risk. Legally, an employer needs to ensure all equipment is safe to use, and where necessary, you need to get advice from someone qualified. In this case, I'd say that's the manufacturer, who would have been asked this question before. If its not being moved, the risk of damage to the unit is minimal. You might want to look at checking things after an incident where it gets damaged - like lighting strikes etc. But at that point you also need to think about whether you trust it for business continuity reasons. I'd also want to look at proper management processes like checking the age of the UPS and battery condition - The risks aren't really around Earth continuity etc, more the high capacity lead acid battery. This assumes big server type UPS's. Small ones that you might put in an office would be different. But I'd be reluctant to plug one into a PAT tester without talking to the manufacturer. You would also want to have some sort of fail-over switch installed so that you can remove the UPS for testing without downtime. A quick google shows this: https://www.apc.com/us/en/faqs/FA158687/. So, it can be done, but really requires specialist knowledge or else you will get a false fail result. You can also do a visual inspection for damage etc. The thing that's got me wondering is if you should PAT test your PAT test machine?

We did this last year and it was great. We got good feedback from our users about how much quicker things worked - especially sims. I don't think we told anyone we were changing servers, but they knew something had been done. We went from a 3 node cluster with SAN and HP servers to 2 dell servers (non-clustered) and local storage + SSD cache. Its a much simple setup which is good. We also were in the middle of our google drive migration - so that drastically reduced the amount of storage we will need in the future. The 2 things we 'lost' were: * no quick migration between hosts - you have to move the VMs storage as well. With a 10g link, this isn't really an issue in practice. For maintenance, it just takes minutes to transfer. For DR, we replicate to our old servers + have backups. Live migration still works well, even during the day. * if a server gets moved to the other host, then you may have to update your veeam job. I think you can just tell it to backup everything from a server, so again probably not a big issue. I would recommend working closely with your server supplier if you want to do storage spaces direct as it has (or had) some specific hardware requirements. It can be expensive if you get the wrong disk controllers etc.

Is this to enlarge images on the wall for tracing etc? Could you do something slightly different and use an old data projector?

That's the big advantage of google slides. At the last school we set up, I found an old powerpoint with pictures and converted it to slides. Then when someone asked to put something on there I just shared it with them and told them they were now responsible for it. Next time someone else asked, I shared it with them as well. If anything gets deleted or changed there is the history.

We also do google slides and chromebits or Raspberry pis. This means it can be someone else's problem once setup and made to work. Used to use Xibo, but only 1 or 2 staff were ever trained on it. It was way over complicated for putting slides on screen unless you need to do complex schedules.

You could try setting up a mirror port on the switch and wiresharking it.

It'l be high voltage but low current won't it? Earthing might not be enough to protect it as the earth wire won't be zero ohms, just close to it - maybe 0.1 ohms. So there could still be a voltage difference between different points. There could also be EMP. Daft question - did you check the monitor? I'd check your getting all the voltages from the PSU. Could also try switching the CPU. Or completely disconnect the PC overnight and try again later.

I do have a google sheet + apps script. Not sure its ready for GitHub yet, but I can share it if its wanted.

We have some flashforge printers in DT here. Probably better suited to a classroom environment than a prusa style one as its more contained. If its going into a back office that's less of a concern. We have a creality printer as well, but the cabling to the heated bed isn't well supported and there are reports of these wearing out and overheating/causing fire. There are cable chains you can print out to give better support to this.

We have a Magicard Enduro 3e. Seems to do the job, but haven't timed it. Should be a bit quicker than your though.

Is anyone doing timetabling or admissions for next year? There are some of these things that block other users from using sims whilst they are running. It won't necessarily show up in task manager.

We use the chrome sign builder as well. its running a google slides show which is shared with whoever wants to upload content. You could probably run Chrome in kiosk mode on a normal PC, and point it at the correct URL for the google slides show.

So to recap - * light can get from one end of the fibre cable to the other, on both sides. * light can get from one end of the patch cables to the other, on both sides. * reversing one of the patch cables didn't fix it * new sfp modules didn't fix it * reversing the patch cables back the way they were after replacing the sfp modules didn't fix it. Do you have anything like VLANs or LACP trunked links in use? If these aren't configured correctly they can cause links to not come up. Is there another pair on the fibre cable you can try? Can you swap each bit out on another fibre link? If you have the right patch cables, I'd try connecting a switch locally using the fibre. If none of that works, I'd get a fibre installer to come in and verify the link. It could be damaged in a way that doesn't transit enough light to get a connection.

I'd swap the modules out, one end at a time. We've had several modules fail on the receive side, so there is no easy way to see if its working or not as you would still get the red laser coming out.

3CX should also do what you want. I'm not sure if the free/standard version can do the groups and permissions like you want, but the paid versions will be able to do it. It wouldn't be too expensive for a system of that size if you had to go down the paid route.

It probably depends how well documented your current system is. I think we had a day offsite programming and a day onsite, which was probably about right. I did a lot of work before this making sure we knew how many phones, where they where and what sort of phone we were putting in. The system is pretty easy to use and update. Especially for adding phones. The main issues will be things like IVRs and setting up any buttons on the handsets. Its possible to do most of this in house, but there is a fair amount of leg work entering mac addresses and names. It depends on how much of this you want to do. Our provider had a handy spreadsheet we filled in and they process that in some way. You may also want to spread it over a couple of days so that you can get the basic system up and running, then switch over your phone lines - which may well need to be booked in advance. You might be better off getting a couple of the yealink phones and the free licence. You can play around with it and see what you think.

Another vote for 3cx. So easy to manage and add phones to.

I used QWinff the other day.

We have one of these at one site: https://www.amazon.co.uk/BLACK-DECKER-Cordless-Dustbuster-Flexi/dp/B07G9BX8ZQ/ref=sr_1_10?keywords=black%2Band%2Bdecker&qid=1556793061&s=gateway&sr=8-10&th=1 We also have our own henry on another site. I prefer a hoover over an air duster as its less mess. Its also great when drilling walls etc.

I think the magicard printers show up as normal windows printers, so most programs sould send something to them. We use a custom web app and print them from chrome or IE. I think there was some talk of using MS Word and a Sims report on edugeek at one point. You'd just need to set the page size to the card size and get the orientation correct.
