Siemens OOHC941 Multipurpose Fire and CO Detector

The Siemens OOHC941 combines optical smoke sensing, thermal sensing, and electrochemical carbon monoxide detection in a single addressable device, using Advanced Signal Analysis (ASA) technology to distinguish real fire signatures from nuisance sources. UL 268 7th Edition listed with built-in ISOtechnology isolation, it provides comprehensive life-safety coverage in one detector head, reducing the number of devices required per protected space while maintaining Cerberus PRO signaling line compatibility.
