The detectors use heat detection instead of smoke detection to sense fire, since many cooking, lighting and heating methods used by people living in informal settlements produce smoke, and provide the nearest fire station with the GPS location of the fire, allowing for proactive early response. Because the urban informal settlements have a dense nature, there is a risk factor that enables the rapid spread of fires. In order to provide a sufficient early warning; a community-wide alert is required. In the event of a fire, devices within 60-metre radius range will ring together, creating a community-wide response to the danger. This buys time for communities to become proactive in rapidly spreading fire risk situations.
