433MHz RF Communication Wireless Smoke Alarm with 10 Year Battery Life and Photoelectric Sensor
Product Overview
The smart 433MHz Interconnected Smoke Detectors provide reliable fire detection for modern homes and commercial spaces. Using 433MHz RF communication, these alarms can link up to 100 meters, ensuring that when one detector senses smoke, all interlinked units trigger simultaneously. This feature offers instant notification across multiple rooms or floors, improving overall safety.
With a photoelectric smoke sensor, the detectors respond quickly to smoke while reducing false alarms. Powered by two CR123A lithium batteries, they offer long-term reliability. The alarm sound exceeds 85dB at 3 meters, making it clearly audible even in noisy environments. Compact and lightweight, the detectors are easy to install on ceilings or walls without disrupting the room design.
