The Kidde KN-COPE-D (part CP9000) is a 9-volt battery-powered combination photoelectric smoke and CO alarm with voice alerts. It announces 'Fire! Fire!' or 'Warning! Carbon Monoxide!' — clearly identifying the hazard. The photoelectric sensor detects visible fire particles associated with slow smoldering fires. A Smart Hush feature silences nuisance alarms. Peak level memory alerts when the unit has detected CO at 100 PPM or higher. Front-loading battery compartment makes battery replacement easy and ensures proper installation. This model is replaced by the 30CUDR-V.
Why is photoelectric sensing better for certain locations?
Photoelectric smoke sensors detect visible fire particles produced by slow smoldering fires earlier than ionization sensors. They also produce fewer nuisance alarms from cooking smoke and steam, making them better suited for kitchens and areas near cooking appliances.
What model replaces the KN-COPE-D?
Kidde recommends upgrading to the 30CUDR-V, the current-generation DETECT battery combo alarm with voice alerts, photoelectric sensing, self-testing, and updated UL 217 10th Edition certification.
