SpyglassTM IR3 (V) flame detectors provide industry leading reliability and detection speed for hydrocarbon fires. The color or optional near-infrared video technology in the SG50-F-IR3-V allows visualization of these fires which are often nearly invisible to the human eye. Video capture of a fire event includes one minute before the alarm and up to three minutes after the event. The SpyglassTM family of triple IR and UV-IR flame detectors provide top-tier optical flame detection with faster detection time and performance over long distances.

• Highest immunity to false alarms
• Triple IR uses three wavelengths in the infrared spectrum from 4.0 to 5.0 μm to detect hydrocarbon fires
• HD, or composite, video output with automatic HD video recording of events on IR3-V
• 5 selectable sensitivity levels
- Ultra-fast detection within 40 milliseconds for fireballs or explosions
- Fast flame detection, <1.5 s for standard fire up to 30 m. Option for <0.5s, in compliance with NFPA 33, available
• Optimized CO2L option for aircraft hangars, helipads & truck loading racks available
• Detects up to 262 ft. (80m) for a 1 ft (0.1m²) n-heptane fire
• Event logger: Alarms, faults (& videos for IR3-V) are logged to non-volatile memory
• Universal outputs, 3 and 4 wire, 4-20 mA sink / source, Fire, Auxiliary and Fault Relays. RS485 port using
• Modbus RTU
• Built-in-Test (BIT) – Automatic and manual internal self-test of window cleanliness and the overall operation of the detector
• *HART® 7 units available - Easy configuration and diagnostic capability, including dirty optics warning for
preventative maintenance needs
• Window heater to avoid condensation and icing
