Okay, UK fire alarm question. Do they all talk, and politely tell you that, possibly, the building just might be on fire, and suggestion you might want to start thinking about sauntering out, instead of ringing a bell or siren and flashing lights? When I was in London earlier this year, I experienced two fire alarms going off. One was a test, which the voice politely announced was going to happened, made the building could possilby be on fire spiel, and then apologized for the disturbance. The other was an actual alarm at my hotel, which also featured a voice apologetically saying there was a fire. If the flashing lights hadn’t have woke me up, the alarm was not going to get me evacuating.
