40/40L-LB UV/IR Flame Detector Series.
Model 40/40LB, with Built-in-test option provides a combination of UV and IR sensors, where the IR sensor operates at a wavelength of 2.5-3.0 µm, and can detect hydrocarbon-based fuel and gas fires, hydroxyl and hydrogen fires, as well as metal and inorganic fires. The UV/IR flame detector senses radiant energy in the short wave section 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 UV sensor incorporates a special logic circuit that helps prevent false alarms caused by solar radiation. Due to increased reliability, the 40/40 Series warranty period has been extended to 5 years and is SIL2 (TUV) approved to IEC 61508.Features: UV/IR Dual-Sensor Solar Blind Automatic Built-In-Test (BIT) and Manual- to assure continued reliable operation (in 40/40LB only) Heated window - for operation in harsh weather conditions (snow, ice, condensation) Multiple output options for maximum flexibility and compatibility Relays (3) for Alarm, Fault and Auxiliary 0-20mA (stepped) HART Protocol for maintenance and asset management RS-485, Modbus Compatible High Reliability - MTBF - minimum 150,000 hours Approved to Safety Integrity Level 2 (SIL2 - TUV) - Model 40/40LB only User Programmable via HART or RS-485 Hazardous area zones: Zones 1 & 2 with IIC gas group vapors present Zones 21 & 22 with IIIC dust type present Ex approved to: ATEX & IECEx FM/FMC/CSA TR CU (EAC) 3rd party performance approved EN54-10 (VdS) FM3260 Marine Approval MED "Wheelmark" approval (DNV) Reliability IEC61508 - SIL2 (TUV)
The Model 40/40LB Flame Detector is an electronic device designed to sense the occurrence of fire and flames and subsequently activate an alarm or an extinguishing system directly or through a control circuit.
The UV/IR Radiation Flame Detector is a dual spectrum optical detector sensitive to 2 distinct ranges of the radiation spectrum, both of which are present in fires. The detector monitors the protected volume, by measuring the radiation intensity in it, within 2 frequency ranges of the electromagnetic spectrum, namely the Ultra-Violet (UV) and the Infra-Red (IR) spectrums.

18 Principles of Operation
The detector integrates 2 dependent channels, in which appropriate detection pulses are registered and further analyzed for frequency, intensity and duration.
The IR sensor in Models 40/40LB is sensitive to radiation over the range of 2.5–3.0μm, where the H2 emission has a unique spectral peak that enables detection of hydrocarbon fires, gas fires, hydroxyl, and hydrogen fires, as well as metal and inorganic fires.
The IR sensor in models 40/40L4 and L4B is sensitive over a range of 4.4–4.6μm spectral band where the CO2 has a unique spectral peak that enables it to detect the combustion product of any organic substance.
The UV sensor is sensitive to radiation over the range of 0.185–0.260μm. The UV Channel incorporates a special logic circuit that eliminates false alarms caused by solar radiation and other non-fire UV sources. Furthermore, the UV channel’s sensitivity is stabilized over the working temperature range.
Simultaneous detection for some types of radiation in both the UV and the IR channels having an intensity that exceeds the detector’s preset Warning level results in a Warning signal.
Simultaneous detection of radiation in both the UV and the IR channels having an intensity that exceeds the detector’s preset Alarm level results in an Alarm signal.
Simultaneous detection of radiation in both the UV and the IR channels having an intensity that exceeds the detector’s preset Flash-Fire Detection level results in an immediate Alarm signal.
Since the preset dual range and level of radiation, as well as the flickering pattern, are characteristics of real fire, all other radiation sources apart from actual fire are not detected, thus avoiding false alarms.
Used some months and replaced due to changes in project. Sell with mount and sun protection cap.
