At what temperature can smoke detectors begin to malfunction?

Smoke detectors are designed to function effectively within a specific temperature range to ensure safety and reliability. They can begin to malfunction at temperatures that exceed their operational limits, which typically is around 120°F (48.8°C). At this temperature, the sensitivity of the smoke detector may be compromised, potentially leading to false alarms or failing to detect smoke efficiently.

Operating above this threshold can cause the detector to respond improperly to smoke particles, as its sensors may not react as intended to the presence of smoke or increased heat. Hence, the choice of 120°F clearly illustrates the critical point beyond which the reliability of smoke detectors begins to wane, highlighting the importance of maintaining them within regulated temperature environments for effective operation.
