Autronica AutroFlame BG-201 Dual-IR Flame Detector

Category:

Product Overview

The Autronica BG-201 is an interactive point flame detector designed for the rapid detection of fires involving carbonaceous materials and hydrocarbon fuels.

Two infrared sensors monitor different sections of the fire’s infrared spectrum. The detector evaluates both signals to confirm the characteristics of a genuine flame while rejecting sunlight, hot equipment and other nuisance-alarm sources.

It is particularly suitable for engine rooms and other demanding marine environments.

Typical Marine Applications

  • Ship engine rooms
  • Generator and machinery spaces
  • Turbine enclosures
  • Fuel-treatment rooms
  • Pump rooms outside hazardous zones
  • Ferry and cargo-ship machinery spaces
  • Workshops and industrial production areas

Replacement Application

Autronica also offers a BG-201 maritime replacement kit for replacing the older 601F-M detector. The kit includes the BG-201 detector and a suitable mounting plate.

Maintenance Requirement

The detector’s sapphire window should be inspected and cleaned regularly. Water, ice, snow or heavy contamination on the sensing window may reduce its effective detection range.
