Esser 802375.IN IQ8Quad FM Isolated OTblue Multi-Sensor Detector
Product Code: 802375.IN
The OTblue measurement chamber, thanks to its advanced sensor arrangement, distinguishes flaming fire, smoldering fire, and high heat-generating events in a single housing; test fires TF1 through TF6 within the EN 54-9 scope are recognized. Because signals are monitored over time and compared with one another, adaptation to environmental conditions occurs automatically. FM approval highlights this model in export-oriented industrial projects. The isolator is located within the housing.
