Spyglass SG50 Optical flame detectors for difficult fires

The Spyglass SG50 serie optical flame detectors

With the implementation of optimised algorithms and a new on-board video functionality in colour or near infrared depending on the type of fuel, the Spyglass SG50 series offers unrivalled performance for detecting a wide variety of fires. Several versions are available:

• Spyglass IR3 Flame Detector

The IR3 flame detector detects fuel and hydrocarbons gas fires at long distance while offering the highest immunity to false alarms thanks to its triple wavelength design.

• Spyglass IR3-H2 flame detector

Detects "invisible" hydrogen gas fires at long distance and offers the greatest immunity to false alarms thanks to its triple wavelength design. The IR3-H₂ can also detect fires involving other substances such as ammonia, silane, as well as fires emanating from new energy transition processes.

• Spyglass UV/IR & UV/IR-F flame detectors

The UV/IR and UV/IR-F flame detectors use an IR sensor and a UV sensor that is insensitive to sunlight to detect fires quickly.
- The UV/IR model is set to a wavelength that detects a wide variety of fuels, including hydrogen, ammonia, silane and metal fires.
- The UV/IR-F model is set to the optimum wavelength for detecting hydrocarbon fires but sacrifices the ability to see non-hydrocarbon fires such as hydrogen. It is optimised for ultrafast response to fireballs and explosions.

• CO2L detector - Hot CO2 release

The CO2-L flame detector has been optimized to provide fast, reliable detection on a wide range of hydrocarbon fires where combustion exhaust gases may be present. As well as detecting actual fires, the detector analyzes and rejects any false signal from hot CO2 exhaust. Typical applications: civil or military aircraft hangars, heliports, tunnels, loading docks, etc.

SG50 optical flame detectors options

• Integrated high-definition video option

The high-definition (HD) camera provides a clear image of the fire via a video system, enabling you to observe the fire from a distance, analyze the situation accurately and implement the appropriate safety measures. A video of one minute before and up to 3 minutes after an event is recorded by the detector for post-fire analysis of the causes of the incident.

Color is preferred for hydrocarbon fires, to give a realistic view. Some fires involving fuels such as hydrogen or alcohol can be practically invisible to the human eye and do not show up well on color video. Near-infrared video is the best solution for obtaining a clear visualization of the extent of flames with specific fires.

• The NFPA33 option - Ultra-fast detection

The NFPA33 option is available in UVIR, IR3 and IR3-H2 configurations. It enables ultra-fast detection of fires in high-speed production processes such as spray booths for the automotive industry, high-speed printing and coating, conveyors and fast-moving vehicles, etc. The NFPA33 standard requires the detector to activate an alarm in case of an event in less than 0.5 seconds.
