These have been shown to be more effective in detecting a smoldering fire. They can be obtained in hardware and general merchandise stores. Look for a P icon on the label for the photoelectric type. Placement and number of detectors are discussed in the links below.Carbon monoxide detectors are also required in homes and apartments prior to a transfer of property.

Ask your agent where to find the detectors you’ll need. Most hardware stores carry them and many offer smoke and CO combination detectors.
