The 449CT is a self-diagnostic smoke detector that continually monitors its own sensitivity and operational status.
It will provide you with a visual trouble indication if it drifts out of sensitivity range or fails internal diagnostics. This patented technology meets the National Fire Prevention Association's testing requirements, without the need for external meters.
A Higher Level of Safety Within Your Reach
In addition to advanced diagnostic technology, the 449CT is designed to reduce false alarms from dust, insects, radio frequency interference, and external light. And with such a low cost, it's a perfect choice to ensure your safety.
