Description

IFD20-IR2 dual infrared flame detector is a kind of new-type intelligent fire detection equipment. This detector adopts the high-performance dual infrared sensing technology, and is provided with three infrared sensors with different wavelengths and narrow-band filtering. One sensor is used to reflect the central wavelength of the flame information, and the other is used to monitor other infrared radiation in the environment. Combined with the flicker characteristics of the flame, the radiation spectrum with flame characteristics can be identified as a fire alarm by means of the operational analysis with the high-speed microprocessor and technical algorithm. This detector is able to suppress the interferences such as sunlight, lightning, electric welding, thermal radiation, electromagnetic interference, mechanical vibration, etc., is provided with strong anti-interference capacity, and can quickly respond to and accurately identify the flame signal.

Frequently Asked Questions (FAQ)

What is the maximum detection range of the IFD2020 Flame Detector? +

The detector has a maximum detection distance of up to 50 meters for a 0.3m x 0.3m n-heptane flame, with a detection angle of 90°.

How does the dual infrared sensor system prevent false alarms? +

It utilizes three narrow-band filtered infrared sensors of different wavelengths. By combining spectral analysis and flame flicker characteristics with a high-speed microprocessor, it effectively filters out environmental interferences like sunlight, lightning, welding, and thermal radiation.

What types of output signals are available? +

The detector provides a standard 4-20mA analog signal output, a faulty relay passive output (AC:3A 250V, DC:3A 30V), and a fire alarm relay passive output (AC:3A 250V, DC:3A 30V).

Is the detector suitable for hazardous and industrial environments? +

Yes. The detector features a robust aluminum alloy shell, an IP66 ingress protection rating, and is certified with explosion-proof markings (Ex db IIC T6 Gb / Ex tb IIIC T80°C Db), making it suitable for demanding conditions.

How can the sensitivity of the detector be adjusted? +

The sensitivity can be easily adjusted externally using a magnetic rod, eliminating the need to open or remove the cap of the detector shell.

What are the working temperature and voltage requirements? +

The detector operates on a DC18-30V voltage range with a low working current of ≤30mA (at DC24V), and functions reliably in ambient temperatures from -40°C to +70°C.
