IR-12.1

DATA AND FACTS

Dual-Band-
Infrared-Flame Detector

The IR-12.1 dual-band infrared flame detector detects flickering fires with open flame with the involvement of carbon based on the flickering and the spectral line of CO2. The device is very suitable for open flames with smoke development. It does not respond to sunlight, light bulbs (continuous/modulated), fluorescent lights, flying sparks, arcs, hydrogen flames, small flames without flickering or metal fires.

The ambient radiation is compensated for with the aid of dual-band sensors, through which the sensor has very high insensitivity compared to other IR sources. IR-12.1 has relay outputs for malfunction and alarm, internal monitoring of the operating voltage and integrated test equipment.
