re: X-Sense Smoke Alarms

Holy crap, I'm glad that stayed at smoldering and never got any further than that!  That's terrifying.  I once had a spark from easing the rear edges of my bandsaw blade start to smolder in some of the saw dust around the blade guides, despite my best efforts to clean it before I did that (I always vacuum my band saws out when I change blades... never easier than when there's no blade).  Luckily I remembered a warning story from ToddJB from back in the day, and make sure I always check for that kind of thing, just in case.  

I like the idea of the interconnected smoke detectors.  I've got smoke and carbon monoxide detectors in my shop, but if they go off and I'm not around to hear it... is it really a fire? (Yes, the answer is yes).
