UV-IR Control Detector

The UV-IR Control Detector from Nero Industries ensures rapid and accurate flame detection by simultaneously monitoring ultraviolet (UV) and infrared (IR) radiation emitted during a fire. By requiring confirmation from both UV and IR sensors before generating an alarm, the system significantly enhances detection reliability while minimizing false triggers.

The detector is housed in a copper-free aluminum, explosion-proof enclosure and is designed to meet IP67 protection standards, allowing it to remain submerged under 1 meter of water for up to 30 minutes. This makes it suitable for extreme operational environments.

With more than 40,000 units actively operating in the field, the UV-IR Control Detector protects engines and crews across military armored vehicles, electric vehicles, buses, aircraft, jet aircraft, and ships.

UV-IR control detectors are optical fire detection devices used to identify fires by detecting specific light wavelengths emitted by gases, smoke, and vapors during combustion.

During a fire event, flames generate distinct UV and IR radiation signatures. UV-IR detectors sense these emissions and trigger the fire alarm system at the earliest stage, enabling rapid intervention and reducing the risk of damage, injury, or loss of life.

UV-IR control detectors are widely used in both fire detection systems and industrial fire protection applications, including:

• Military and armored vehicles

• Petrochemical facilities

• Oil and fuel storage areas

• Ships and marine platforms

• Power plants and energy facilities

• Industrial production and storage areas

Their ability to detect fire in radiation-intensive environments makes them ideal for locations where conventional detectors may be ineffective.

UV-IR control detectors are available in different configurations depending on application needs:

Dual-Spectrum Detectors

Detect both UV and IR radiation simultaneously for highly sensitive and reliable fire detection.

Single-Spectrum Detectors

Detect either UV or IR radiation, typically used in specialized environments.

Linear Detectors

Scan extended areas such as long corridors or conveyor systems.

Point Detectors

Monitor specific locations or confined spaces for flame detection.

Spark Detectors

Used in large industrial environments to detect ignition risks.

Radiation-Resistant Detectors

Designed for facilities affected by radiation, such as nuclear power plants.

The Nero Industries UV-IR Control Detector consists of a sensor module and an electronic controller housed in an explosion-proof enclosure.

Key technological elements include:

• Integrated UV and IR sensors, both required for alarm activation

• Automatic Optical Integrity (AOI) self-test system

• Internal optical test source that periodically checks lenses, sensors, and circuitry

• Optional air shield for dusty environments

• Tri-color LED indicators for visual status monitoring

• High immunity to false alarms

• Automatic self-checking of optical and electronic integrity

• Rapid and reliable fire detection

• Visual status indication via LED system

• Not affected by lightning, solar radiation, hot objects, or artificial lighting

• FM Approved, CE Marked, and ATEX Compliant

UV-IR control detectors are evaluated according to internationally recognized standards, including:

• EN 54 – European fire detection and alarm systems standard

• UL 268 – Performance testing for fire detectors

• FM Global – Industrial fire protection performance testing

• NFPA 72 – Fire alarm system performance requirements

Compliance with EN 54 and UL 268 plays a key role in validating detector performance and reliability.

UV-IR control detectors are designed for early fire detection by identifying flame radiation signatures before smoke or heat levels become critical.

By detecting UV and IR emissions simultaneously, these detectors:

• Trigger fire alarms at an early stage

• Enable rapid fire suppression response

• Reduce damage to assets and infrastructure

• Enhance safety for personnel and operators
