Smoke, heat and carbon monoxide detector IQ8 OTG, optical-thermal-chemical802473Smoke, heat and carbon monoxide detector IQ8 OTG, optical-thermal-chemicalFeatures and AdvantagesTechnical DataAdditional Information:We recommend testing the integrated CO sensor using our CO test gas (art. no. 805583) or CO cartridge (Art. No. 805553) as part of maintenance.Carbon monoxide (CO) gas sensors generally respond to carbon monoxide (CO) emitted during a fire. However, they also exhibit cross-sensitivity to other gases, such as oxygen (H2), acetylene (C2H2) or nitric oxide (NO).Specific gas-sensor designation on the fiber optic cable: gold ring.Supply Scope:Socket detector must be ordered separately.
