Oggioni UV/IR Flame Detector

Product Description

The Oggioni UV/IR Flame Detector is a combination of a UV and an IR flame detector that utilizes a microprocessor for sophisticated electronic signal analysis. The IR part of the flame detector has an additional alarm criterion: the analysis of the flame flicker frequency. The UV and the IR sensors must both exceed their alarm thresholds to initiate a fire alarm. The UV/IR flame detector has good false alarm rejection since the UV and the IR sensors do not share false alarm sources. The UV/IR-210/1 flame detector can thus be applied in areas where single UV or IR flame detectors could potentially cause false and/or unwanted alarms. Common applications in which the three models of 210-series flame detectors can be used can be found in the table below.

Application Example

The applications in which the UV/IR-210/1CZ flame detector can be used are:

• Hydrocarbons storage and processing including tank farms  
• Hydrogen storage and processing  
• Chemical storages, fuels, paint and solvent storage  
• Oil and gas pipeline and pumping stations  
• Fuel service stations  
• Engine rooms  
• Monitoring of machinery  
• Aircraft hangars 
• Car, bus, tram and train parking 
• Paint spray booths  
• Recycling and waste processing plants  
• Electric power transformers  
• Atriums  
• Biogas setups and stables

Features

• Monitors higher hydrocarbon flames (wood, paper, petrol) but also lower hydrocarbons such as methanol and methane
• The UV and UV/IR flame detectors detect hydrogen flames.
• Good immunity against the influences of:
  • direct and reflected sunlight
  • artificial light, such as fluorescent tubes and glass covered halogen lamps.
  • arcs and electric discharges (static or from e.g. electric motors).
  • the radiation from arc welding provided that the distance to the arc welding is >4 m (UV/IR) or >3 m (IR3) from the detector
• IR3 flame detector is suitable for smoky fires
• Automatic sensor test (built-in self-test) which monitors the sensors and the electronics of the flame detector for its proper operation
• Switches to set latching/non-latching alarm relay output

Benefits

• Rugged sensors make the detector suitable for virtually all fire types
• Sophisticated software enhances the reliability and availability of the detector
• Design of the housing and the swivel mount avoid mounting errors with regards to grounding
• Automatic sensor test (built-in self-test) enhances the reliability and availability of the flame detector
• A pressure compensating element avoids additional cost of maintenance caused by moisture build up and increases the lifetime
• Nonincendive (non-sparking) design enhances the reliability and the availability and with a reasonable add-on price.
• Warranty whichever comes first 36 months after installation or 42 months after supply
