Nittan Europe Ltd Hipley Street Old Woking Surrey GU22 9LQ Document: Product: Reference: Description: Technical Manual EVC-IR F04-60044. Conventional Infrared Flame Detector (EVC-IR) is a flame detector which monitors infrared energy emitted during a fire. PAGE 1 OF 6 Technical Manual: Product: EVC-IR Flame Detector Issue: 5 PAGE 2 OF 6 Date: 5th April 2016 1.0 General. The Conventional Infrared Flame Detector (EVC-IR) is a flame detector monitoring infrared energy emitted during a fire. The Flame detectors are designed to monitor flame in large and high-ceiling areas such as an atrium, or a gymnasium where Heat or Smoke detectors are unable to detect fires quickly. In addition, if this detector is installed near machinery which could be an ignition source, this detector can detect small fires at an early stage. Main Characteristics: • Provides reliability and cost-effectiveness by employing dual infrared wavelengths. • Provides a supervision angle of 100°（）±50°. • Omniview 360°LED Fire Alarm Indicator permits visibility from any angle. • Embedded Self-test function detects a sensor fault and contamination of Element Window Glass. 2.0 Part Identification.

The detector monitors fire parameters in the following three ways. CO2 Resonance Emission By analysing the light spectrum emitted from a fire, it is determined that the light reaches a peak at 4.3μm in the Infrared area as shown in Figure 2. This is called CO2 Resonance Emission emitted from high temperature CO2, which is a combustion product. The detector detects fire by monitoring this light emission. Technical Manual: Product: EVC-IR Flame Detector Issue: 5 PAGE 4 OF 6 Date: 5th April 2016 Figure 2: Diagram for Spectrum of Flame and Temperature Objects Flame Flicker Frequency A fire exhibits expansion and contraction influenced by the balance of burning materials, oxygen and heat energy. This causes flame flicker. Pyroelectric infrared detection which is used for this detector considers this flicker as a change of the amount of infrared. It does not have sensitivity to a heat and light source since the amount of light for these sources does not change. The frequency of fire flicker is considered to be 1～10Hz, and the frequency filter circuit removes excess noise. Dual Wavelength System All objects which have temperature emit infrared. However, the black body infrared does not have a characteristic peak. To utilise this difference, a second wavelength sensor has been added and the size is compared. i.e. it detects fire when the output of the first wavelength is greater than the one of the second wavelength. i.e. If the first wavelength level ＞ the second wavelength level，detects fire Conversely, if the first wavelength level ＜ the second wavelength level，does not signal a fire condition By doing this, it is possible to discriminate the heat source which would be a cause of false alarm more effectively. 3.2 Indicator (Omniview) Employing a 360°Omniview indicator, the detector can be installed in any orientation. Sensors can be installed vertically or horizontally. Indicator can be viewed from any angle. 0 1 2 3 4 5 6 7 20 40 60 80 100 0 Sunlight High-temperature heat source (1000℃) Flame Wavelength [µm] Relative Intensity [%] [%] Far Infrared Region Infrared Region Near Infrared Region Ultraviolet Region Visible Region Low-temperature heat source (0℃) Second wavelength area First wavelength area Technical Manual: Product: EVC-IR Flame Detector Issue: 5 PAGE 5 OF 6 Date: 5th April 2016 3.3 Self-test Function This detector has a self-test function which checks for contamination of the Element Window Glass and the status of the sensor.

Even transparent windows, such as glass or plastics, can be obstacles, to Infra-red radiation. • Sensitivity reduction and detection fault may occur where vibration and electromagnetic interference occur constantly. • Sensitivity reduction and detection fault may occur where there is a constant high heat source flicker.
