Whats the difference between Smoke detectors and Heat Detectors ?
The difference between smoke and heat detectors is obvious by the name. Smoke detectors are more sensitive to sensing smoke; heat detectors are more sensitive to changes in temperature. They both detect fire typical parameters, however they are not interchangeable. A smoke detector warns of fire when it senses the products of combustion (soot) in the atmosphere. As anyone who has a smoke detector too close to the kitchen knows, a smoke detector goes off very quickly, even in small amount of smoke. There are slight differences between the two types of smoke detectors, but they both operate by detecting the products of fire combustion. Heat detectors warn of fire when the temperature in the area around the smoke detector reaches a certain level. Heat detectors do not notice smoke. Some studies show that heat detectors may not provide early enough warning to aid escape from a life-threatening fire. However, a heat detector could be valuable additional protection in areas such as kitchens
