At what temperature must smoke detectors not be installed in Fahrenheit?

Smoke detectors are designed to operate effectively within specific temperature ranges to ensure their reliability and responsiveness in detecting smoke. The installation of smoke detectors in environments that exceed these temperature thresholds can lead to false alarms or failure to activate during a fire event.

For typical residential and commercial smoke detectors, the maximum allowable ambient temperature for installation is often set around 100 degrees Fahrenheit. This is to avoid interference with the detector's sensing technology, which could be triggered by high heat alone without the presence of smoke.

Therefore, installing smoke detectors at or above 100 degrees Fahrenheit could compromise their functionality, making it essential to follow these guidelines to ensure safety. Knowing the appropriate temperature range for smoke detectors helps ensure that they will perform optimally when needed, thus maintaining the effectiveness of fire alarm systems.
