First Alert Carbon Monoxide Alarm - tear-down

One of my First Alert Carbon Monoxide Alarm’s expired. This gave me an opportunity to look inside and see what’s inside this little gadget. Here is a picture of the tear-down for those who are interested: First Alert - Single Station Carbon Monoxide Alarm - model #: CO614 <img src="/img/2016/01/img_20160103_184823.jpg?w=1024" alt="IMG_20160103_184823"> <img src="/img/2016/01/img_20160103_184904.jpg?w=1024" alt="IMG_20160103_184904"> <img src="/img/2016/01/img_20160103_184946.jpg?w=1024" alt="IMG_20160103_184946"> The specification for the carbon-monoxide sensor used in this model can be found here .
