Not sure I'm a huge fan of the all-in-one approach. I'd prefer a distributed network of sensors. Also, looking at their ad copy --- sensing fire using a temperature sensor is a fool's game. By the time the temperature changes appreciably, you're in deep trouble, depending of course on the sensor location.
