Hmm, this might amuse.

Years and years ago I was one of the designers for a system for a Welsh Fire service; radio comms pick-a-back on their voice system, doing our usual stuff ... sound the alarms, turn on the station lights, retract the engine heaters, call up the reserve crew or in some stations the main crew. All of this was backed up by a very substantial UPS system in each fire station. All stations but one worked well.

The one station that didn't was reporting spurious mains failures over and over "and it's not true ... the mains is solid!".

I had the installation people talk me through the behaviour. "It reports mains failure every evening somewhere around 8pm. It reports the power is restored at around 7am for a coupole of hours, then it reports power fail again and it does that all [redacted] day long.".

"Well", say I, "It's been connected to the central heating system then, hasn't it!".

Irritated denials. Our guys are not that daft, woulkdn't have made such a mistale, etc. But they did agree to check "to prove me wrong".
Well they checked and they came back very appologetic indeed. Yes, the UPS had accidentally been connected to the central heating thermostat.

It happens.... at least we sorted it, nobody died.
