Final answer:
NFPA 72 sets guidelines for smoke detector installation, prohibiting their installation outside of the specified temperature range (below 32°F or above 100°F) unless they are designed for such conditions.
Step-by-step explanation:
According to NFPA 72, smoke detectors should not be installed if the ambient temperature is expected to be below 32°F (0°C) or above 100°F (37.8°C), unless they are specifically designed and listed for use in those conditions. NFPA 72 is a standard that provides the requirements for fire detection, signaling, and emergency communications, including the installation and maintenance of smoke detectors. It is crucial for the proper operation of smoke detectors that they are installed within the temperature range for which they are listed and designed.
