Esser 782431 Three-Channel IR3 Ex Approved Flame Detector, 65 m Range

A flame detector approved for explosive atmospheres that evaluates hydrocarbon-containing flames across three separate infrared channels. The built-in test function enables the device to self-diagnose; since sensitivity is adjustable in four levels, the same model can be used both at close and long distances. Under test fire conditions, it has a range of 65 meters and a response time of five seconds. It provides class 1 protection up to 26 meters on walls and 45 meters height on ceilings with vertical mounting.
