D-A410 detector not only overcomes the disadvantage that detectors using common infrared scattering technology are insensitive to black smoke with small particles, but also can pick up fire with obvious rise of temperature such as alcohol flame, thus extending its application range.
D-A413 Intelligent 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.
