Spyglass SG50-F-IR3-V

Technical Description – Spyglass SG50-F-IR3-V Triple IR Flame Detector

The Spyglass SG50 IR3 and IR3 V are the next generation of the IR3. It has been introduced to further enhance the protection and safety for these high risk and high value industries.

​The Spyglass SG50 IR3 and IR3 V will detect fires and explosions extremely fast, thus allowing preventative action to be initiated even more rapidly and minimising the consequences!

Spyglass Flame Detectors with Integrated High-Definition Video

High-Definition (HD) Camera allows clear imaging of fire at 100 ft. (30m) distance. Connecting to a video system allows remote verification of fire, allows the first responders to be aware of the exact situation before entering the hazardous area, and can be used for post-fire analysis of the cause of the fire. Video recording of 1 minute pre-event and up to 3 minutes post-event is captured by the detector.

Video units are available with either colour or near-infrared video. Colour is best for hydrocarbon fires and to give a realistic view. Some fires from fuels such as hydrogen and alcohol can be virtually invisible to the human eye, and do not show up well on colour video. Near-infrared video is best for these hard to see fires as it more clearly shows the extent of the flames.

A Closer Look

The unmatched detection times and distances are:

• Highest immunity to false alarm
• 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
• Optimised CO2 L 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.
• Stainless steel tilt mount with horizontal and vertical adjustment
• SIL 2 compliant – suitable for use as part of a SIL 2 compliant safety system
