Triple IR Optical Detector
Triple IR Optical Detector
Ultra-fast fire detection is critical in environments where explosive threats, flammable materials, or high-energy impacts can generate fireballs within milliseconds. In military, industrial, and energy-sector applications, delayed detection can lead to catastrophic consequences. The Triple IR Optical Detector developed by Nero Industries is engineered to detect fireballs almost instantly, delivering highly reliable flame detection with exceptional immunity to false alarms in the most demanding conditions.
Triple IR Optical Detector
The Triple IR Optical Detector detects the fireball created when ammunition penetrates armor within 3 milliseconds, before pressure and heat reach destructive levels. Upon detection, it immediately transmits an alarm signal to the vehicle or system control unit, enabling rapid fire suppression response in platforms exposed to RPG and ATGM threats.
Using three independent infrared (IR) wavelength bands, the detector analyzes heat and light signatures at different frequencies. An alarm is generated only when all three IR sensors simultaneously confirm a flame signature, ensuring precise detection and superior false-alarm rejection.
The detector is designed by Nero Industries engineers in accordance with NATO STANAG 4317 and MIL-PRF-62546C standards and has successfully passed extensive environmental testing.
Purpose of the Triple IR Optical Detector
The primary purpose of a Triple IR Optical Detector is early and accurate fire detection in environments where conventional flame or smoke detectors may be ineffective.
By evaluating multiple infrared wavelengths, the detector can:
Identify genuine flame signatures
Distinguish fire from non-fire heat sources
Enable rapid intervention before fire escalation
This makes triple IR technology particularly suitable for high-risk industrial, military, and energy-sector applications.
Designed for Harsh and Mission-Critical Environments
Triple IR Optical Detectors are designed to meet IP67 protection standards, allowing them to remain submerged under 1 meter of water for up to 30 minutes.
They also feature advanced false-alarm immunity, ensuring no reaction to:
Sunlight and solar fluctuations
Vehicle headlights
Welding arcs
Infrared heaters
Cigarette ash
These detectors actively protect engines and crews across armored vehicles, electric vehicles, buses, aircraft, jet aircraft, ships, and industrial facilities. To date, over 40,000 detectors are successfully operating in the field.
