as far as i know, if an alarm goes off after midnight, the emergency services are automatically called after a couple of minutes unless someone calls the all night porters lodge in york house.
it's crazy that so many alarms keep going off all over campus - last year the one in our flat didn't even go off when someone set fire to the oven.
one of my flat mates (at about 11:30 pm) decided he was hungry so put some burgers under the grill. he realised that he wanted some chips with his burger so he closed the grill (please note he didnt turn off the grill) and went to the pit shop (by the laundry) to get some!
when i went through the kitchen to the bathroom to brush my teeth (it being 11:30 at night) and noticed the flames coming out of the grill!
so i turned off the grill and phoned the night porter who came and yelled at my flat mate for being a total pillock.

Yep, they do come out if it's between midnight and 6 am (have seen it a couple of times here).

The kitchens actually have heat detectors (not smoke alarms obviously), so they only go off if it gets very hot in there (probably by "hot" they mean "the heat detector's on fire!").

Yup, that's a grand example of idiocy. I bet he's glad that you actually spotted it!

Hey, I just wanted to say thanks so much for sticking up for me in my latest Friends Collage post. It means a lot to me to know that I have someone on my side when I've been feeling like I haven't had anyone. Thankyou :)

Any time.
