There are many factors when we talk about residential smoke detectors and carbon monoxide detectors.  We can talk brand, model, photoelectric, ionization, combination, dual, hardwired, interconnected, battery operated, battery back-up, plug-in, etc.  Some of the determining factors needed to answer the questions you may have are: When was the house built? Has the house gone through any major renovation?  specially electrical upgrade? If so, what year did the renovations take place? Is the house a single family or multifamily?  To quickly and easily answer some of these questions click here to take a look at our quick reference chart for smoke detectors and carbon monoxide detectors.
