The smart 433MHz Interconnected Smoke Detectors are engineered to provide superior fire safety for residential and commercial spaces. These alarms link up to 100 meters via 433MHz RF communication, ensuring that all connected units trigger simultaneously when one detects smoke. This instant notification system reduces response times and enhances protection for large or multi-level buildings.
Using a photoelectric smoke sensor, the alarms detect smoke efficiently and minimize false alerts. Powered by two CR123A lithium batteries, the units ensure long-term, maintenance-free operation. The alarm output exceeds 85dB at 3 meters, providing audible alerts even in noisy environments. Compact and lightweight, the detectors can be installed on ceilings or walls with minimal disruption.
Our Interconnected Smoke Detectors stand out due to their rapid interlinking capability and reliable 433MHz RF connection. The detectors synchronize instantly, ensuring every alarm in the network activates at the same time. Their high sensitivity photoelectric sensor provides accurate smoke detection, while the 10-minute mute function allows temporary silencing of false alarms.
Low standby current (<50µA) and alarm current (<70mA) contribute to long-lasting battery life. Compliance with EN 14604:2005/AC:2008 ensures they meet international safety standards. The 10-year lifespan guarantees minimal maintenance costs, making them suitable for property managers and B2B clients seeking scalable fire safety solutions.
We specialize in producing high-quality Interconnected Smoke Detectors with full customization options. OEM and ODM services include logo branding, packaging design, and functional adjustments to meet client needs. Advanced production lines and rigorous quality control maintain consistency in each unit.
Our factory supports large-scale orders and provides professional after-sales services, including technical support, spare parts, and warranty solutions. B2B clients can rely on us for timely delivery, consistent quality, and expert guidance for installation and maintenance.
These Interconnected Smoke Detectors are ideal for apartments, hotels, schools, office buildings, and multi-room residential properties. The extensive linking range covers large spaces, providing timely alerts throughout entire buildings. Ceiling or wall installation is straightforward, and their compact design ensures minimal visual impact.
Facility managers and property owners can meet fire safety compliance requirements efficiently, protect occupants, and reduce potential property damage. They are particularly suitable for multi-unit structures where synchronized alarms are essential.
