Spectrex SharpEye Flame detector Ex-Proof IR3 – 20/20MI-1

The Spectrex SharpEye 20/20MI (TSD-2020MI) is a compact, high-reliability triple-spectrum IR flame detector, engineered for the demanding fire protection needs of industrial and commercial sites handling flammable materials. It features outstanding false alarm immunity and rapid, accurate flame detection even in challenging environments.

Key features

• Triple spectrum IR detection:Fast and accurate recognition of both hydrocarbon and other flames using three IR bands.
• Exceptional immunity to false alarms:Highly resistant to sunlight, arc welding, and reflective surfaces.
• Extended detection distance:Up to 40m (0.1 m² n-heptane reference fire), 100° × 100° field of view.
• Automatic and manual built-in-test:Ensures continuous reliability and diagnostics.
• Low power consumption:Up to 80% less than conventional detectors.
• User-programmable functions:Configuration via software, adjustable outputs.
• Stainless steel housing:Industrial durability with IP66 + IP67 protection.
• Outputs:Relays (alarm, fault), 4-20 mA, RS-485 Modbus, widely panel-compatible.
