The heat and smoke detector is used to detect fires in their early stages. The device incorporates two sensors: of heat and of smoke. The use of two types of sensors makes it possible to detect all types of fires in a quick and reliable way. More over ,the detector has an additional optical signalization so that the detector’s fire alarm can be seen from a distance. The detector operates in the AWEX fire alarm system. The element can be mounted on addressable monitoring lines, both loop type, as well as radial.
