Choosing the right one prevents false alarms and missed fires. If a fire started tonight, would everyone wake up in time? Read on: it takes a few minutes and could save you a lot more than that. **In this guide you will see:** - Smoke = earlier warning, most rooms and corridors. - Heat = kitchens, garages, dusty or steamy areas. - The wrong detector type is a leading cause of false alarms. Quick answer Smoke detectors react to smoke particles and give earlier warning, which is why they're used in most rooms and escape routes. Heat detectors react to temperature (a fixed temperature, or a rapid rise) and are used where smoke, steam or dust would cause false alarms, such as kitchens, garages and workshops.
