Ultraviolet detector
UV detectors respond to radiation in selected ultraviolet bands. They can be fast for suitable fires but may require careful control of arc, lightning or other UV-producing nuisance sources.

What is an industrial UV/IR flame detector?
An industrial UV/IR flame detector is an optical fire detector that evaluates ultraviolet and infrared radiation from a flame using model-specific signal processing. It initiates an alarm or output when the observed signatures meet the detector’s approved criteria.
Combining two optical bands can improve discrimination between fire and some non-fire sources, but it does not make a detector immune to every false alarm or suitable for every fuel. Selection must use verified response data for the credible fire, range and environmental conditions.
Reliance Fire Protection Systems supports surveys, design coordination, supply, installation, testing, commissioning and maintenance planning from Mumbai for high-hazard projects across India.
Optical Flame Detector Technologies
Single-spectrum infrared detector
IR detectors evaluate radiation in a selected infrared band and model-specific flame behaviour. Response depends on fuel, range, atmosphere and interfering sources.
UV/IR detector
UV/IR devices combine evidence from ultraviolet and infrared channels to confirm a model-defined flame signature and reject some single-band disturbances.
Multi-spectrum IR detector
IR3 or other multi-spectrum detectors compare multiple infrared bands to distinguish target flame signatures from background radiation for approved fuels.
Visual flame detector
Imaging or video-based analytics may identify flame-like spatial and temporal patterns and provide visual verification when approved for the application.
Combined fire and gas detection
High-hazard projects may coordinate optical flame, heat, smoke and gas detection as independent or complementary protection layers.
UV/IR Flame Detection Design Workflow
Technical reference: BIS lists IS/ISO 7240 Part 10:2012 for point-type flame detectors; ISO confirmed the source standard as current in 2025. Special-risk and hazardous-area projects may require additional product, system, electrical, functional-safety or authority approvals.
Selection and Coverage Factors
Fuel and flame signature
Hydrocarbon, hydrogen, alcohol, solvent, sulphur, metal and other fires produce different radiation. Use approved test data for the actual fuel.
Range and fire size
Published range normally relates to a defined test fire, orientation and sensitivity setting. Smaller, obscured or different fires may be detected differently.
Field of view
The detector must see credible fire locations within its tested cone of vision. Coverage is three-dimensional and changes with distance and angle.
Obstructions and mounting
Equipment, structures, pipes, vehicles, storage and future modifications can block line of sight. Mountings must remain stable and accessible.
Nuisance radiation
Sunlight, hot equipment, welding, flares, lightning, lamps, reflections and modulated sources must be assessed against detector immunity data.
Atmosphere and optics
Smoke, fog, rain, dust, oil film, salt, dirty windows and absorbing gases can attenuate radiation or obscure the detector’s view.
Safety limitation: A flame detector only responds to radiation that reaches a suitable, correctly configured and functioning sensor. It does not prevent ignition or suppress a fire unless an approved system performs the required action. “False-alarm immune” and universal response-time claims should not be used without model-specific evidence.
Industrial Applications and System Interfaces
Oil, gas and petrochemical
Process units, loading areas, pump zones, compressor areas and storage facilities may require rapid line-of-sight detection and hazardous-area equipment.
Power generation
Turbines, generators, fuel systems, cable areas and auxiliaries may use flame detection with shutdown, ventilation and suppression interfaces.
Aircraft and transportation facilities
Hangars, fuel handling, maintenance areas and transport infrastructure require fuel-specific detection and coordinated foam, deluge or alarm actions.
Warehouses and process plants
High-value or fast-developing hazards may use optical flame detection where smoke or heat detection alone cannot provide the required response.
Hydrogen and clean-burning fuels
Low-smoke or special-fuel fires require technology explicitly tested and approved for the fuel and expected environmental conditions.
Alarm and suppression interfaces
Relay, analogue, digital or network outputs may initiate panel alarms, emergency shutdown, isolation, deluge, foam or remote monitoring through approved logic.
Testing, Maintenance and Management of Change
Functional response testing
Use the manufacturer-approved flame simulator or test method at the required positions and verify detector indication and control-panel receipt.
Cause-and-effect proof testing
Test alarms, voting, delays, shutdowns, isolation, suppression release, notification and remote monitoring against the approved matrix.
Optical condition
Inspect and clean detector windows, shields and accessories using approved materials; review contamination diagnostics where provided.
Alignment and obstruction review
Confirm mounting direction and line of sight after equipment changes, scaffolding, storage, vehicle routes, pipework or structural modifications.
Hazardous-area integrity
Inspect enclosure, glands, seals, earth continuity, junctions and certification-related conditions under the site’s hazardous-area regime.
Records and impairment control
Document tests, faults, bypasses, cleaning and changes, and provide temporary risk controls when any detector or interface is unavailable.

Industrial UV/IR Flame Detector FAQs
What is an industrial UV/IR flame detector?
It evaluates ultraviolet and infrared radiation from a flame using model-specific signal processing and generates an alarm when approved criteria are met.
How does UV/IR reduce unwanted alarms?
It compares evidence from more than one optical band, improving immunity to some disturbances but not every nuisance source.
Which fires can UV/IR detectors detect?
Fuel response is model-specific; select the detector using verified test data for the credible hydrocarbon, hydrogen or other fire.
Where should flame detectors be installed?
Provide clear line of sight and verify model-specific range, cone of vision, obstructions, nuisance sources, weather, contamination and access.
Can a UV/IR detector be used in a hazardous area?
Only when the complete installation has the certification and protection concept required for the classified area.
How are flame detectors tested?
Use manufacturer-approved test equipment and verify optics, response, panel indication and all required cause-and-effect actions.
Do you provide industrial flame detection across India?
Yes. Reliance Fire Protection Systems supports enquiries from Mumbai across India, subject to project requirements.
