Standard smoke alarms fail in unconditioned spaces like garages, utility rooms, and attics due to airborne dust. Choosing thermal sensors designed for rapid temperature changes ensures reliable notification without frequent false alarms.
You do not need a smoke alarm in the garage because dust, exhaust, and temperature swings cause frequent false sirens. Instead, install an interconnected heat detector to identify garage fires safely.
A heat alarm detects rapid temperature spikes or high thermal thresholds rather than smoke particles. It provides reliable early warning in areas where fumes and steam trigger false alarms.
