IRT-021-A Flame Detector Technical Manual KARF & SCOOT Chapter 1. Overview 1.1 What is a Flame Detector? A fire is a phenomenon in which a substance burns in the air or oxygen with light, heat or flame, and generally burns with heat, smoke or flame. Especially, the flame shows unique combustion characteristic at the early stage of fire. At this time, a large amount of infrared and ultraviolet energy of different wavelength band of ultraviolet (UV) and infrared (IR), which is not visible to the naked eye, is emitted. Infrared Flame Detector IRT-021-A is an infrared three-wavelength flame detector employing three digital infrared sensors that detect different wavelength characteristics within the infrared wavelength range (3.9 to 4.7 μm) emitted from the flame. -

Page 13: Chapter 4. Product Installation
IRT-021-A Flame Detector Technical Manual KARF & SCOOT Chapter 4. Product Installation This section provides basic instructions for installing the detector. It does not attempt to cover all the standard practices and rules of the installation. Instead, it highlights specific aspects and provides some general guidelines for qualified personnel. Where applicable, special safety precautions are emphasized. CAUTION The detector is waterproof (IP67 class) so water does not leak through the case or cable gland. It is also recommended that the part connected to the fire boat (other end of cable) be thoroughly waterproofed so that it is not affected by external influences. Product damage due to improper wiring is not covered by the warranty. -
Page 14: Selecting Installation Position
IRT-021-A Flame Detector Technical Manual KARF & SCOOT 4.2 Selecting Installation Position The type and placement of fire detectors should be determined in consultation with Karf&Scoot expert technical consultants or site experts. Note that the IRT-021-A series is flame detector only; they cannot detect flammable gas or dust environments. Please contact Karf & Scoot if you need a gas detection system. a. -
Page 15: Detector Installation
IRT-021-A Flame Detector Technical Manual KARF & SCOOT Install considering changes in ambient temperature. Do not install the detector where there may be frost on the sensor window. Install using the rated power (SMPS). 10. If you install the detector in a dusty environment, you should check and clean it frequently. 11. Install away from welding, halogen lamps, heater etc. to prevent false alarms. 12. As flame detector is electrically connected to the enclosure and internal ground (for the purpose of passing the 6kV withstand voltage test), it may have an effect on the detector when installed on a steel frame or steel material. It is recommended to install it through a non-electrical plastic or wooden plank. 13. The flame detector is waterproof (IP67), so water does not leak through the case or cable gland. It is recommended that the part connected to the ex-proof junction box be completely waterproof in order not to be affected by external influences. The cable port is not covered under warranty unless it is stored in a waterproof container. -

Display LEDs and First Boot There are 2 LEDs on the screen of the IRT-021-A series flame detectors; red and green. Solid Green: Power is ON, and the detector is operating normally. Solid Red: Alarm. During the first boot, the red LED will flash 5 times then; The green LED will flash 5 times, the green LED stays steady and detector surveillance starts. b. Normal Working Condition The green LED is on when the detector is operating normally. -
Page 17: Cone Of Vision
IRT-021-A Flame Detector Technical Manual KARF & SCOOT 4.5 Cone of Vision The IRT-021-A flame detector has a 90° cone of vision so it can monitor a floor-to- ceiling area and extends up to 50 meters. Horizontal field of view (90°) and vertical field of view (+45° down, -45° up) are shown in Figure 6 and Figure 7. Figure 6: Vertical Field of View Figure 7: Horizontal Field of View CAUTION Lowering the detector’s height above the tracked item will increase the size of the shadow areas. -
Page 18: Under Ceiling Installation
IRT-021-A Flame Detector Technical Manual KARF & SCOOT Figure 8: Shadow Effect Shadow Effect 4.7 Under Ceiling Installation During a fire, smoke rises and can form a thick layer at ceiling height before flames appear. Dense smoke can block some wavelengths of light emitted by flames. This can reduce the sensitivity and speed of the flame detector. To prevent smoke from blocking the field of view; It is necessary to leave a distance between the flame detectors and the ceiling during installation. -

Page 20: Chapter 5. Maintenance
IRT-021-A Flame Detector Technical Manual KARF & SCOOT Chapter 5. Maintenance Inspect the IRT-021-A flame detector and wiring regularly for signs of physical damage. Do not use solvents or abrasive cleaners on the detector and its optics. Clean only with microfiber cloths moistened with pure alcohol, without touching your hands, or use optical grade wipes. WARNING- EXPLOSION HAZARD Contact of the mounting bracket with the wet area can cause static discharges that may cause an explosion in a flammable atmosphere. In hazardous areas, use only a clean, damp cloth (dampened with water) to clean the mounting bracket. No special preventive maintenance other than cleaning is required. Routine inspection of the flame detector is recommended as follows: Check the position and alignment of the flame detectors. -
Page 21: Chapter 6. Troubleshooting
IRT-021-A Flame Detector Technical Manual KARF & SCOOT To ensure that the flame detection capability of the flame detector is maintained, periodic inspections should be made to ensure that it is not contaminated by permeable dust and similar substances. The flame detector should be stored in a clean and dry place. Temperature and humidity data must be within the ranges specified in section 3.4. - Page 22 IRT-021-A Flame Detector Technical Manual KARF & SCOOT Contact www.karfandscoot.com/en +90 216 314 56 57 info@karfandscoot.com Importer: Manufacturer: Karf & Scoot IRT Korea Co.
