Description
Ensure your home stays protected with the Kidde FireX KF20 mains powered smoke alarm. This reliable detector uses an optical sensor to monitor your environment, providing an essential layer of safety for your family. Because it is powered by 230V mains, you can rely on consistent performance, while the built-in 9V alkaline battery backup ensures the device continues to function even during power outages. Designed for convenience and ease of use, the KF20 includes a combined test and hush button. This allows you to perform regular functional checks easily and provides a way to temporarily silence nuisance alarms if they are triggered by non-emergency situations. An integrated LED indicator provides a quick way to check the current status of the unit at a glance. For comprehensive whole-home protection, this alarm is part of the FireX wired range. If you install multiple Kidde FireX mains alarms, they can be interlinked. This means if one alarm detects smoke in a single room, every connected alarm in the house will sound, giving you more time to react. This smoke alarm is BSI and CE certified, meeting recognized safety standards.
