C-9104 Conventional Ultraviolet Flame Detector detects fire by analyzing ultraviolet radiation of material flaming. It's applicable to places where open fire, fire with intense flame radiation and fire without smoldering stage take place easily, as well as places where quick response to a fire is required. Used together with other detectors, it can sense fire in time to minimize losses as much as possible.
The detector is DC powered, which powers signal processing circuit after voltage stabilization, the UV sensor needs 300V voltage or so, which is provided after boosted by transformer. When there is ultraviolet light on the sensor, it discharges due to photoelectric effect, and the strength of discharge is in proportion with the intensity of UV light. Signal processing circuit analyzes and processes its output signal, then compares with alarm threshold and outputs alarm signals. The alarming mode of the detector is current output; it's shorted by internal 680? after alarming.
