Triple IR Optical Detector
TRIPLE IR / FLAME DETECTION Triple IR Optical Detector
Ultra-fast fire detection is critical where explosive threats, flammable materials or high-energy impacts can create a fireball within milliseconds. The Triple IR Optical Detector evaluates three infrared wavelength bands to deliver rapid flame recognition while rejecting common non-fire radiation sources in demanding military, industrial and energy-sector environments.
A multi-spectrum infrared flame detector developed for applications where fast fireball recognition and strong resistance to false alarms are essential to the protection strategy.
Three-Band Infrared Detection for Rapid Fire Events
Fireballs produced by fuel ignition, explosive threats or high-energy impacts can develop before conventional heat or smoke detection has time to respond. Triple IR technology addresses this challenge by evaluating flame-related radiation across three independent infrared wavelength bands.
The Triple IR Optical Detector is specified to detect the fireball associated with armor penetration within 3 milliseconds. An alarm is generated when the detector's three IR channels confirm the required flame signature, supporting rapid signaling to the connected control and suppression architecture.
Multi-Wavelength Confirmation with Advanced Signal Processing
The detector monitors IR1 at 4.5–5.5 μm, IR2 at 3.0–3.6 μm and IR3 at 0.8–1.2 μm. By comparing these separate infrared regions, the system can evaluate whether the observed radiation pattern is consistent with a genuine flame event.
The source documentation identifies ultra-fast semiconductor IR quantum sensors, two high-performance microprocessors and advanced software algorithms as part of the detection architecture. Requiring confirmation across all three IR channels helps reduce unwanted alarms from non-fire radiation sources.

Fast Response with False-Alarm Rejection
Triple-band confirmation is used to separate real flame signatures from common optical and thermal interference. The supplied source specifically identifies immunity to sunlight and solar fluctuations, vehicle headlights, welding arcs, infrared heaters and cigarette ash.
The detector is also described as suitable for harsh environments, with IP67 protection. The source states that this level allows the detector to remain submerged under 1 meter of water for up to 30 minutes.
