The Time of Greenwich reports (http://bit.ly/yEAwlQ ) some hardware store owners say people also have been bringing in their existing alarms to check and replace batteries after the deadly Stamford fire.
Officials say the improper disposal of fireplace ashes sparked the blaze, which killed 7-year-old twins Grace and Sarah Badger; their 9-year-old sister, Lily; and their grandparents, Pauline and Lomer Johnson.
Their mother and a friend were able to escape the burning mansion, which later had to be torn down.
Fire officials say the deaths underscore the importance of having working smoke detectors and an escape plan, and taking precautions with fireplace ashes and other flammable materials.
