Honeywell Searchline Excel Infrared Open Circuit Gas Detector

The response speed is much higher than that of point detectors

Fault safety design: No unexposed fault modes, no problem of detector gas path blockage

The installation position requirements for detectors are lower, and there is no need to strictly align with potential leakage points

Easy installation and debugging, can replace multiple point detectors, and reduce overall deployment costs
