Guest MF22 Posted September 8, 2022 Report Share Posted September 8, 2022 Had a recurring fault on an Advanced panel with Hochiki devices for a while. It’ll turn up randomly one day and then disappear for weeks. Starts off on the log with “interrupt - unknown device”, then immediately goes to “corrupt data” and then eventually goes back to normal. I’ll link a short video of the log. My first thought is to replace the detector, but the issue is it’s at the top of a lift shaft so have to get the engineers out to give me access. Anybody got any ideas of what it might be without having to go up there? Thanks. Quote Link to comment Share on other sites More sharing options...
green-foam Posted September 12, 2022 Report Share Posted September 12, 2022 Only a guess, water damage. Quote Link to comment Share on other sites More sharing options...

Managed to get up there Friday to change the detector, all was well until this morning when the fault came back. I’ll have to arrange to get back up and strip it all down, replace the base as well as the detector and check for any signs of water.

green-foam Posted October 30, 2023 Report Share Posted October 30, 2023 The person who initially asked, did so over a year ago and has never been back, if you have changed the device and you still have problems, I suggest you look at the devices "either side" to make sure they are not wet or corroded. You could also try looking for on line technical support from advanced. Quote Link to comment Share on other sites More sharing options...
Fire Fence UK Posted June 20 Report Share Posted June 20 I believe a device sends an interrupt when it reaches a certain threshold before it goes into alarm, it sends an interrupt to stop the loop polling all the devices so it can put data on the loop, if there is an interrupt followed by corrupt data it sounds like a faulty device. Corrupt data that jumps around between different devices can be caused by corrosion on the cable itself, and if there is water in the device, like someone mentioned above, be careful because it can blow the loop card on an advanced, and from experience that sometimes does not put a fault on the panel at all.

green-foam Posted June 24 Report Share Posted June 24 Nice input 🙂 however, it has fallen on deaf ears as the original poster asked way back in 2022, and has never been back, so I would hope has solved the problem by now. The two who asked later, neither have ever posted again, so we will never know if they looked at any of the other devices. (As I suggested.) The moral of this is, always check the date a post was last active before you post.🫢 Quote Link to comment Share on other sites More sharing options...
