That's fine I have a similar mindset, but it's worth making the point. We see enough fairly competent DIYers come by here, struggle and give up.

Your not going to find anything like that in the engineers manual, the manufacturers expect competence from industry training. They are not sold to end users. Even if you are capable of working with electronics and electrical installations knowledge of the programming and industry terms is were most have an issue. The closest thing to a generic service guide can be found on ACT website. Many of the tests you should be comparing to the readings on the commissioning paperwork, without this you'll need to use your experience of the systems. By the time you have bought the equipment and tested it out, you could have had a guy do it?

Yep sounds like failure due to lack of maintenance. They are pretty basic panels and show no obvious warnings of potential failure until they don't work. You maybe lucky and the charging circuit recovers when the system is checked, battery replaced and power cycled. Someone that knows what they are doing is a sensible idea. It's going to need a full check you haven't mentioned the external box sounding which is also of concern.

People also take things too literally because most stuff is read online with there own bias and no context. It's fuelling cancel culture and making people think negatively about others without knowing them or the intent of the text. I'm relatively conservative when it comes to wanting legislation but I believe we should seriously consider not allowing Under 16's to have internet access on personal devices. Not an easy topic to tackle but we restrict other things like smoking or buying petrol or knifes etc. Issues now is much of high school work relies on having a smartphone, this has de-facto set the age of owning a device at 11, 2 years before the US COPPA that most of the big internet services seem to use as an age limit. Much of the new Online Safety Act is useless, it's trying to target platforms but it will never work. Much like an anti-virus it can only ever be reactive as content is found, even that is only going to be suitable on public facing information. So private echo chambers are unlikely to be found, it may even move users towards more private forums. Lets ignore the fact it will impose new restrictions forcing sites to harvest more data about people to age gate them. Seems to have a requirement to back door any encryption. That it can be bypassed relatively simply and reduce growth of our UK data centres. Clearly people with no clue how the internet works have drafted it, at least they'll make some money out of big tech in the short term I suppose...

"Never have we been so connected and yet so lonely" People no longer associate shouting at people on twitter as there being another human at the other end... Face to face conversations about polarising topics with nuance and respect are getting a rare occurrence in day to day life... People are put in there own social media minority bubbles grouped by advertising algorithms, they are living in an echo chamber of there own opinions until they feel like a majority... IMO, I could go on...

Assuming if you wait 90 seconds or so and then the keypad will allow disarming... then you have some DD243/BS8243 setting enabled to lockout the keypad on entry.

Any and all. It could be the PSU but I'd expect to see more in the log. Alarm wiring shorting to mains earth (earth fault) can pull all the zones low. Need more to go on really, just assumptions with very little info.

Never taken one apart but I'd agree I'd certainly have a crack at repairing it considering the cost.

I wasn't suggesting this caused the fault, but it would lock the system out until you reset it. I'd be using my meter checking all the voltages or maybe for signs of an earth fault or interference.

Tamper engineer reset maybe on...

Is there anything else in the log either side of this? Are these panel zones or an expander? What's on the system?

You have likely blown a fuse, why you have power going to the contact is beyond me tho. The codes are unlikely to be the default ones so pointless trying them unless you know that's right.

What doesn't work?

It's Risco, they go loopy... I don't like waste but they are generally panels I prefer to bin than takeover.

System may have had settings programmed in the router. I'd imagine you have an installer, you'll need to contact them.

From what I recall there is a menu somewhere else to add a Custom Name to the Zone Types list.

A Texecom Live panel would likely replace it like for like but most professional kit with remote access is subscription via a registered installer. Someone has to pay for the servers and secure network to route all this remote access traffic. Burn marks on the PCB are likely due to age and not having it serviced regularly.

They use Perimeter and Interior terminology like the Powermax from what I recall.

The PCB material makes me think 70s. The capacitors maybe look more modern? It's probably hard to date if they would have been hand built and low batch numbers?

Radiovisor specialised in Active IR beams. Never seen any so old tho. They work as a pair. Usually an IR beam is emitted then reflected back it detects if something blocks this.

I suppose these are using proprietary Crypto1 format? If so maybe look at the documentation from the people that RE'd it?

The interference reed switch will make it tamper. Unit needs closing up and the magnet part the correct way around on the correct side of the reed part. You'll have fun re-installing it too if you plan to do that.

Spoons watered down, you want Export.

For someone with all the kit and knowledge you seem to assume a lot, instead of diagnosing it. We may as well speak into the void at this point. Your repeating the same thing and clearly not reading or taking in what people are saying, your the one with the issue and looking for help...

It's in the manual, Type 1 or 2 copper intruder cable. So CQR Pro 8 or equiv. This should be tripled up in most cases. The transmission is TTL, you can expect occasional network errors, it logs them until you reset them. Something is wrong if you are watching them tick up live.
