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.
Our Interconnected Smoke Detectors excel due to their reliable 433MHz RF connection and wide linking range. When one detector is triggered, all connected alarms respond immediately, providing comprehensive coverage. The photoelectric sensor ensures high sensitivity, detecting smoke efficiently while minimizing false alarms.
Additional advantages include a 10-minute silence function, low standby current (<50µA), and alarm current under 70mA. Compliant with EN 14604:2005/AC:2008, these detectors meet strict safety standards. With a 10-year product life, they reduce maintenance and replacement costs, making them ideal for B2B clients seeking durable solutions.
Our factory specializes in producing Interconnected Smoke Detectors with full OEM and ODM services. Clients can request custom logos, packaging, and technical modifications. Advanced production lines, automated testing, and strict quality control ensure consistent product performance.
We handle bulk orders efficiently and provide after-sales services including technical support, replacement parts, and warranty coverage. This makes our detectors an excellent choice for large-scale residential, commercial, and industrial safety projects.
These Interconnected Smoke Detectors are ideal for multi-room homes, office buildings, hotels, schools, and other facilities. The 100-meter linking range allows alarms to cover large areas, ensuring early warning for all occupants. Ceiling or wall installation is simple and unobtrusive.
Property managers and facility operators can rely on these detectors to meet fire safety regulations, protect occupants, and prevent property damage. Their synchronized alarm feature is especially valuable in multi-unit buildings.
