Intelligent Base Mounted UV Flame Detector

Product code: 55000-022APO

55000-022APO - Intelligent Base Mounted UV Flame Detector
The Intelligent Base Mounted UV Flame Detector is designed to protect enclosed indoor areas where open fires may be expected. The detector has a fast acting response to flames up to 25m away and is equipped with a single UV sensor with a narrow spectral response in order to discriminate between flames and most spurious sources of radiation.

Electrical Description

The detectors are loop powered and need no external supply. A remote LED alarm indication may be connected to the flame detector.

Operation

The detector is sensitive to ultraviolet radiation emitted by flames during combustion. Since it requires only UV radiation the detector responds even to stationary flames with no flicker like cigarette lighters and blue gas flames. The detector is set to respond to ultraviolet radiation (185−260nm) emitted by almost all flames, including those invisible to the naked eye, e.g. hydrogen fires. The detector has a single UV sensor with a narrow spectral response in order to discriminate between flames and most spurious sources of radiation and is designed for internal fully enclosed areas. Caution: The detector will also detect electrical discharges from lightning or arc welding.

Application

UV flame detectors are used when detection is required to be unaffected by convection currents, draughts or wind. These include engine rooms in ships, factories affected by draughts or wind and warehouses. They are fast reacting and respond to a flame more than 25m away. The UV flame detector is affected by arc welding, electrical sparks, lightning, nuclear radiation and UV light sources. For applications where these phenomena are present a UV flame detector should not be used.

Maintenance & Service

The flame detector is designed to give years of trouble-free operation with minimal attention. However the periodic maintenance steps listed below are essential to maintain reliable fire protection. 1. Inform all appropriate personnel of intention to work on the flame detector. 2. Disable any automatic systems that may be activated by the flame detector if not required as part of the maintenance check. 3. Check that the flame detector’s control panel is functioning correctly and shows no faults. 4. Inspect the detector viewing window for any build-up of dust or other contaminants on the optical surface. If necessary clean the optical surface with a cotton wipe wet with commercial liquid glass cleaner. Rinse with clean water and dry with a clean cloth. The detector specification for performance is with a clean optical sensor window. Contaminants like dust, oil and paint will reduce sensitivity. 5. Ensure the detector still has a clear line of sight of the area it is protecting and no obstacles obstruct its view. 6. Check that the detector is securely fitted. 7. Visually check the exterior of the detector for any mechanical or corrosive damage. 8. Test the operation of the detector with either a portable flame sensor test unit or if practical a flickering yellow flame. 9. Reinstate any automatic system disabled during maintenance. 10. Inform all appropriate personnel on completion of the maintenance work and if necessary record this work.
