OOHC941 Siemens Multi-criteria Fire and CO Detector Model OOHC941 Siemens is an advanced, multi-criteria fire | CO detector that incorporates a redundant optical/thermal sensor. Additionally, Model OOHC941 incorporates ASAtechnology a distinctive forward / backward, light-scattering technology that provides high-tech, unparalleled fire detection to the widest range of fire types allowing the detector to distinguish non-threatening deceptive phenomena. Each Model OOHC941 unit is UL 268 7th edition listed incorporating advanced built-in ISOtechnology - True Class-X SLC operation (use is optional) greatly improving system reliability and circuit integrity while providing advanced addressable fault finding. The unit may be programmed as a high-sensitivity detector, with a 0.2 %/ft PreAlarm threshold and 1.0 %/ft Alarm threshold thus meeting the requirements of NFPA 76 Standard for the Fire Protection of Telecommunications Facilities as a Very Early Warning Fire Detector (VEWFD). Each OOHC941 Siemens detector offers a complete and contemporary solution to meet fire and CO life-safety gas-detection specifications. Multi-Criteria Fire / CO Detector detectors can be field programmed for simultaneous and/or independent functionality, depending upon the precise customer and application req(more...)
