Kidde KI-DDOS Optica Intelligent Duct Smoke Detector

Designed for dependable duct fire detection in commercial HVAC, the Kidde Commercial Optica duct smoke detector delivers intelligent monitoring and fast, low-cost installation. The Optica KI-DDOS combines a slim profile—less than 2.5" deep—with standard sampling tube spacing and 45° rotation to simplify retrofits and ensure accurate sampling aligned to duct airflow. Built-in intelligent electronic addressing and diagnostics identify dirty or defective detectors early, helping maintenance teams reduce nuisance alarms and unscheduled downtime.

Technicians benefit from magnet-activated testing and field-accessible connections that require no special tools, while compatibility with 15.2–19.95 Vdc fire panels makes integration with existing security, surveillance, and fire alarm systems straightforward. UL 268 listing provides code-compliant reliability for data centers, retail, healthcare, and industrial facilities where continuous air monitoring is critical. Choose the Kidde Optica duct smoke detector to improve safety, streamline inspection routines, and maintain uninterrupted building operations.
