A Smock/ Heat Detector is offered by us that is more traditionally used in residential properties. Although they are prone to making more mistakes than heat detectors, they do provide an invaluable resource for detecting the first sign of combustion. In short, no home should be without one. Heat detectors are intended to minimize property damage by reacting to the change in temperature caused by a fire. These devices can accurately detect and respond to convected thermal energy. Smock/ Heat Detector is very accurate.
