                Description

                Smoke entering the duct system will be dispersed throughout
                the whole building. The RE-428DU-S duct detectors utilizes
                the photoelectric sensing method and is designed to sense
                the existence of smoke in the duct. This design of the housing
                along with the detector technology is capable of detecting
                unsafe conditions by sampling the air through the duct. When
                the smoke is detected, it will send out a signal that will create
                the proper action to be taken to turn off circulating fans,
                blowers and any other auxiliary devices that are connected to
                the system through Fire Alarm Control Panel. The actions
                taken will enable the management of hazardous smoke
                through the entire space that is being protected by the duct
                detection arrangement.
                This detector can be installed on any side of the duct.
                The detector RE-428DU-S contains an intelligent controlling
                circuit. The circuit adjusts the sensitivity to give an optimal
                function throughout the entire life of the detector.
