Never on mobile but nothing seems broken yet

Even insurance with no idea specify "Redcare or equivalent"... They were the market leader years ago and priorities change, there wasn't much they could do with the product the downsides were part of it's design. Agile/Secure mitigated that for years. Without Redcare Classic they are no longer tied to doing security, to people higher up its probably easier to fold at this point. I think you underestimate how much encryption you use on a daily basis...

Really? Encryption is fundamental to any secure data that needs transmitting, this concept does back centuries to well before computers. Original Redcare was an amazing product back in the day, it would work over wet string, had continuous encrypted signalling and 30s polling with no data costs. Nothing will be able to copy it, it requires having the infrastructure. Obviously there were downsides to the product which will explain the wind down. Everyone is jumping on the massive strength of the Redcare brand to sell there new tat. The product name is known fairly well outside the industry.

It's not just 1 contact tho, it's 3... EOL will be wired different at the controls end. Assuming this is three single doors, convert your 6-core into a data line for an expander adjacent to the first door, take single cables from the expander to each door. Wire it however you want not sure if Orisec supports DP from an Exp. EOL would be better but you could have issues with stuffing 1/4W resistors in tiny old style contacts if your reusing them. Most would replace the contacts. Program panel accordingly. This has the benefits of:- single fault will only take out one door, you can isolate doors individually, you know which door has an alarm or fault without taking the lot to bits, your cable to the sheds is a data line instead of DP so it's tampered in a better way.

I just wouldn't, especially on a modern panel with more options. One zone per device, so you can diagnose any problems. Your sketch seems alright assuming it's DP, time to get the multimeter out take everything apart and work out what's going on.

Why not just use an unmanaged PoE switch at that money...

There is always something else to do...

Date code on the box seems to be Mid October '93 Don't know much about them.

Been given 2 of these, both new but tatty boxes Before I consider them as WEEE I thought I'd document them for the nerds here. Didn't find much info on them from searching.

They are not ideal but they don't really do a lot hence the cost. Shuffle the pins around but you'll get less speed and wattage

Most wired sirens are compatible with wired systems but keeping the same manufacturer means you are likely to have instructions for how to connect there own. Have you proved it's actually the siren at fault?

Tell me something I haven't been ranting about for years...

Having listened to the podcast already it's not related, images came from social media. It will take a defence lawyer to get the evidence thrown out on possible deepfake grounds, for change to happen. If you handle evidence properly with decent kit it shouldn't be an issue.

Don't believe stainless for cable tackers is a thing. Regular galv or painted white is all I have ever seen.

IXP is for third party kit. IProx can't be wireless so I don't see why keypad would be, also a wireless keypad will depend on what other wireless equipment you fit as to if you have capacity at the expander.
