What’s the difference between a smoke alarm and a heat detector?

Smoke alarms sense smoke particles and work best in living areas and bedrooms. Heat detectors are mechanical, battery-free devices built for garages, kitchens, and attics — spaces where dust, steam, and temperature swings cause smoke alarms to false-alarm or fail. TruWatch recommends pairing both — photoelectric smoke alarms in living areas, heat detectors where NFPA 72 says smoke alarms don’t belong.

Mechanical heat detectors: no batteries, no electricity, nothing to forget

Battery-free heat detection for the kitchen, garage, and attic, the rooms NFPA 72 says smoke alarms struggle in.
