Product Features
What this model is for, what it does well, and what to confirm before it goes on a project.
Explosion-proof flame detection in industrial areas where fast infrared alarm response and multiple output interfaces are required.
Three infrared wavebands support flame recognition with strong anti-interference behavior for demanding industrial environments.
RS485, two-wire 4-20mA current loop and three relay outputs let the detector integrate with different fire alarm and control setups.
Window defogging and defrosting plus a wide -25°C to +75°C range help maintain monitoring in tough conditions.
