Because of a new State Law which went into effect on July 1, 2011 the California State Fire Marshal has created  a list of frequently asked questions (FAQ) regarding carbon monoxide devices.

Carbon Monoxide alarms can be purchased at just about any hardware store for a cost between $30.00 and $70.00.    The higher priced units usually have a longer "end of life" and are usually a combination of carbon monoxide and smoke detection.   Consider purchasing a "talking alarm" because it is nearly impossible to quickly discern the exact meaning of a "beep" when it could be indicating a smoke alarm, a carbon monoxide alarm, low battery or "end of life" alarm.  

When Carbon Monoxide detectors are added to a security system, the alarm control stations will visually indicate, smoke, CO, low battery or system trouble.

End of Life:   All Carbon Monoxide detectors, by virtue of how they are designed and how they work, have a scheduled "end of life" which is between 3 and 7 years depending on the unit. At the "end of life", the units must be replaced.
