Last Answer : The sensor on most detectors are life limited to ten years. The legal department probably makes them put 7 years on the box. It is the sensor that wears out in ten years.

Description : Isn't carbon monoxide heavier than air? If so shouldn't CO detectors be put at floor level?

Last Answer : molecular weight of CO ~ 28 (12+16), while the main ingredients of air are O2 = 32 (2 16) and N2 = 28; mixed together, that's heavier than CO. Alone from that, I'd say CO is lighter. Of course ... right says lighter than air . So CO rises. Therefore, again, keep your head down in case of smoke ;-)!
