OTG multisensor (CO) IQ8Quad
802473
Approval: VdS
Multisensor fire detector with integrated smoke detector, heat detector and gas sensor (CO) for preventive and early detection of fires ranging from smoldering fires to open fires through combined evaluation of scattered light, temperature and gas. An alarm is actuated at carbon monoxide (CO) concentration levels that are life-threatening for humans. The detector is provided with an integrated isolator. A parallel detector indicator can be connected. Gas sensor (CO) helps to detect fire alarms, but can additionally serve to signal technical alarm when concentration exceeds safe value without fire situation.
Additional Information:
In the course of installation, we recommend testing the integrated CO sensor with our CO test gas (Part No. 805583) or CO capsule (Part No. 805553).
Durability CO sensor: approx. 5 years
Technical alarm range CO: 10 ppm … 150 ppm
Gas sensors (CO) mainly react to the carbon monoxide arising from a fire (CO). They have, however, also a cross sensitivity to other gases, as for example hydrogen (H2), acetylene (C2H2) or nitric oxide (NO).
Special marking for gas detector on the light pipe: gold ring.
