Life saving carbon monoxide detector how to use one

[trainlinezoo]

Hey Pat....you should talk more about the technical aspects and safety of the product. Telling us about how the gas effects people is just wonderous but how high should I mount this thing? Is the gas heavier or lighter than air? How often is the battery back-up replaced? Here's a good one for those of us with solar trickle chargers....What's the output voltage of the plug in power supply? Is there a way to test Nighthawk's functionality? It's speaker works great but let's test it out!

You can save energy by getting one of these that are battery operated instead of a plug in.
