Could prove useful round here !! :P

Not yet, just wet string.

Years ago I did some work in the local hospital morgue on the Access System. From the day the system was installed they thought they had a ghost meddling with it with lots of banging, with doors locking and unlocking on their own... Hospital Services had fitted the kit, and after some investigation I found the problem. One 2A PSU was running 3 Double mags @1A each. Obviously the doors were taking it in turn to lock and unlock. A big fat 5A PSU fixed it... I can imagine it was quite a bit spooky! (did make me laugh though ) Worst but, apart form the guests, was the 70VAC across the Ceiling Grid and the PSU Earth. Oohh that hurts.. Hospital services didn't give a $h1t...

It sure looks like an R8, but my old manual shows on-board fuses and a central tamper switch on the pcb. You've probably a newer version/production of the R8. Good luck
