The smart 433MHz Interconnected Smoke Detectors combine modern technology with reliable fire safety. With RF433MHz communication, these detectors interlink up to 100 meters, so when one alarm senses smoke, all connected units trigger simultaneously. This ensures comprehensive coverage in multi-room or multi-story buildings.
Photoelectric sensors provide fast, accurate smoke detection while avoiding false alarms. Powered by two CR123A lithium batteries, the alarms offer long-term reliability. At ≥85dB at 3 meters, the alarm ensures prompt attention, and the compact design supports ceiling or wall installation.
The Interconnected Smoke Detectors deliver immediate, synchronized alerts, providing optimal fire safety. The 10-minute mute feature offers convenience, while low standby (<50µA) and alarm current (<70mA) reduce battery consumption. Compliance with EN 14604:2005/AC:2008 guarantees high safety standards.
With a 10-year life span, these detectors minimize maintenance costs. They are ideal for B2B clients requiring reliable and scalable fire detection systems.
Our factory produces Interconnected Smoke Detectors with full OEM/ODM customization, including logo branding, packaging, and technical modifications. Advanced testing ensures every alarm meets high-quality standards.
Bulk production, on-time delivery, and professional after-sales services make our solutions ideal for property managers, hotels, and industrial facilities seeking dependable smoke alarms.
Perfect for apartments, schools, offices, hotels, and commercial buildings, these detectors ensure alarms trigger simultaneously across all linked units. Ceiling or wall installation is straightforward, and the compact design minimizes visual impact.
B2B clients benefit from regulatory compliance, enhanced occupant safety, and scalable fire detection for multi-unit environments.
