Elro SF400S11 K1 Wireless Smoke Detector Set (2 Units) - White

The Elro SF400S11 K1 is a wireless smoke detector set designed for reliable fire detection in residential environments. This set includes two photoelectric smoke detectors that communicate wirelessly, allowing them to alert each other when smoke is detected. Ideal for bedrooms, hallways, and living areas, the system provides early warning to help protect your family and property.

Advantages

Wireless interconnectivity eliminates the need for complex wiring, making installation quick and easy. The photoelectric sensor is highly effective at detecting slow, smoldering fires, reducing false alarms from cooking or steam. With a loud 85 dB alarm and a hush/silence function, you can temporarily silence non-critical alarms. The low battery indicator ensures you are always aware when batteries need replacement.
