This smoke and carbon monoxide detector uses advanced firmware technology to quickly detect fires, giving you valuable extra time to exit, while minimizing false alarms caused by everyday cooking or steam.

Equipped with a 10-year backup battery, this alarm provides continuous protection even during power outages, reducing the chance of unmonitored periods in your home.

This detector can be hardwired and connected with other Kidde alarms so that when one sounds, they all activate simultaneously, ensuring wide coverage and faster alerting to danger.

The detector beeps and blinks a red LED warning light, while voice alerts clearly announce whether it’s fire or carbon monoxide, giving you instant clarity on the situation so you can respond appropriately.
