Also when a cable has been scagged on installation, damaging the insulation, and takes years to break down. I used to see a lot of single-pole
T+E failures like that, where presumably the cables has been strong-armed into a cavity.
What do you think it might be? You have proven it isn't the panel. I assume the PIR is providing a low resistance when operating?
Bearing in mind it will likely still be as high as 30-300 ohms in an older PIR.
Again, it won't be that. Even touching the wires, certainly twisting them, should be enough. Many older PIRs have reed type relays that present a relatively high resistance when closed.
Hi and welcome.
As above, be good to know what they are teaching you!
My advice would be to go over and above and learn as much about IP as you can - doesn't need to cost
so many free resources online.
This isn't the one that Bentley are now making from the original tooling?

lol, we posted at the same time, I gave it away!
ouch!
I had a funny dealing, on the 'M' also that 'lid tamper' inc case and modules was always an eng reset event?
Whilst of course you could set zone tamper to user...
Not sure if that's right but had a play with an M600 last week prior to scrapping.
Yep, I had the old 'recovering battery' problem on one where service had been refused the previous year, and in failing it gave several 'low battery' reports.
My theory is that the frame was quite thin, and right in the sun on the reverse, so it kept heating up on warm days and the voltage went high then low again.
Ah right, so it almost works straight away
Makes me happier I didn't suggest it to my customer with an older 24, as I don't have any other Texe panels close to hand.
'Proper' monitoring was out of the question as it was a rented (albeit quite posh) house.
