A710/IR2 dual infrared flame detector provide a new generation of fire detection capability and technical standards. It adopts two specially designed pieces of narrow-band infrared sensors, which can distinguish the real flame radiation and interference sources effectively and reduce the impact of environmental factors on detector extremely by means of the built-in 16-bit microprocessor and proprietary signal algorithm processing. With multiple sensitivity levels and output options, A710/IR2 can meet more application demands. 


1. Multistage sensitivity for more occasions

2. Excellent false alarm rejection

3. Automatic faults check and alarm

4. Multiple output options to meet different demands

5. Wide detection field

6. 360 degree adjustable universal mounting bracket

7. Particular flame identification technology

8. Explosion-proof design suitable for the hazardous locations of industrial site
