Advanced panel fault - interrupt then corrupt data

[Guest MF22]

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.

Only a guess, water damage.

Thanks for the reply. 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.

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.
