The UV-IR High-Speed Flame Detector (Series 40/40L4) provides a combination of UV and IR sensors in which the IR sensor operates at a wavelength of 2.5-3.0μm, detecting fires, such as: hydrocarbon-based fuel and gas; hydroxyl and hydrogen, and metal and inorganic fires. Series 40/40L4 is identical to the aforesaid UV and IR combination, except the IR sensor works at a wavelength of 4.5 μm, and the IR sensor is only suitable for hydrocarbon-based fires. The UV / IR high-speed flame detectors have considerable durability and weather-related resistance. Specifically, Model 40/40L4-212SF is comprised of the following: 4-20mA (SOURCE) wiring; a Normally Closed (N.C) FAULT relay, and either a N.C or Normally Open (N.O) ALARM relay. Model 40/40L4-212SF has a maximum operating temperature of 167°F (75°C). It is stainless steel by design, and has a 3/4 inch National Pipe Thread (NPT) Taper. This product is Factory Mutual Approved, as well as SIL2 (TUV) Approved to IEC 61508.
