I would assume, in some place like an office with a lot of computer cubicles, the water would make contact with the computers, electrical outlets, etc. and pretty much fry everyone in the building, but I've never heard of that occurring. What prevents electrocution when fire sprinklers go off?
Reset collar is the part where the lock clicks to lock the bike in. The instructions will explain all. But if they don't just twist or click that, and then set the code and your done. Simple like that.
It depends on the candle how close it is to the detector. If the candle has lead in the wick (most do) it will cause more smoke. Keep the candle in an open area away from a draft. If the smoke detector is in your room put the candle as far away as safely possible. Try to find candles with cotton wicks, they produce less smoke. PartyLite is a good candle provider, thier candles have 100% cotton wicks and the wax is parafin so it dissolves and is not too messy. They last longer too. A small candle will not set off the alarm as long as nothing catches on fire, which is why dorms have rules. To protect the students living there.
Three important points (two minutes each): First..E Mc^2 as the source of energy via both fission and fusion. Secondtime, mass, and length vary according to the Lorentz Transform L(v) sqrt(1 - v^2/c^2). Time varies as t t0/L(v), mass as m m0/L(v), and length as l l0 L(v); where t, m, and l are time, mass, and length as observed by someone outside the framework traveling at v velocity. Thirdgravity is a curvature in space(use the bowling ball on a rubber sheet as a model of space curving under mass). Gravity lens in space have been observed verifying the curvatures in space. Those are the highlights as I see them. Check the source for more on the TOR.
