Red Owl Flame Detector
Sierra Monitor's Red Owl flame detectors (3800 Series) are powerful, cost-effective optical flame detectors that can monitor hydrocarbon-based fuel and gas fires at long distances. The Red Owl comes in two models: triple infrared (IR3) and ultraviolet and infrared (UV/IR) technology, with both models enclosed in explosion proof, stainless steel enclosures.
IR3 technology compares three specific infrared wavelength bands and their relative ratios, giving IR3 Red Owl flame detectors the ability to better distinguish between CO2-emitting flames and non-flame IR sources to provide far greater accuracy and minimize false alarms. Using UV/IR technology, the UV/IR Red Owl flame detectors sense radiant energy in the short wave sections of both the ultraviolet and infrared portions of the electromagnetic spectrum. The signals from both sensors are analyzed for frequency, intensity, and duration. Simultaneous detection of radiant energy in both the UV and IR sensors triggers an alarm signal.
The Red Owl has the unique ability to perform continuous self-test to assure proper functionality, removing the need for an external tester. Other features include a heated window to eliminate condensation and icing, HART capabilities for digital communications, low power requirements, and a compact design.
Packaged with the Red Owl flame detector is a companion hand-held remote control. The remote control provides the ability to customize operation parameters of the Red Owl, such as selecting sensitivity levels and the corresponding alarm delay time. In addition to the automatic self-test feature, the remote control can be used for manual, on-demand self-testing.
