This set includes three individual smoke detectors designed for installation on multiple floors, with an 85 decibel alarm signal that ensures audible notification throughout your home. Each detector operates on a long-life battery system that provides continuous protection for 10 years, after which the entire unit requires replacement according to manufacturer specifications. Installation is simplified with included magnetic mounting strips that attach to ceilings without drilling, making placement straightforward and damage-free. These are standalone, non-interconnected smoke detectors that function independently without wireless connectivity or smart home integration. The white plastic housing measures approximately 10 cm in diameter and 4 cm in depth, with a weight of approximately 180 grams per unit. The optical smoke detection technology responds effectively to visible smoke particles, while the test button allows for regular functionality verification. This product meets basic residential smoke detection requirements and is particularly suitable for homeowners seeking straightforward, maintenance-free fire safety solutions. The 10-year battery life eliminates the need for annual battery replacements, providing consistent protection throughout the product lifespan. Each detector features a low battery warning signal that alerts you when replacement is approaching. The package includes all necessary mounting hardware for immediate installation, with clear visual and audible indicators for proper operation status. These detectors are designed for standard residential environments with normal temperature ranges between 0°C and 40°C, making them suitable for most indoor living spaces including bedrooms, hallways, and common areas where early smoke detection is essential for household safety.
