The smart 433MHz Interconnected Smoke Detectors provide reliable fire protection for commercial and industrial applications. Using RF433MHz communication, these detectors can link up to 100 meters, ensuring that when one alarm is activated, all interlinked units respond instantly.
Equipped with photoelectric smoke sensors, they detect smoke quickly while minimizing false alarms. Powered by two CR123A lithium batteries, these alarms are long-lasting and maintenance-free. With an alarm volume ≥85dB at 3 meters, they provide clear warnings across all environments. Their compact, lightweight design allows simple ceiling or wall installation.
The Interconnected Smoke Detectors feature rapid interlinking, high sensitivity, and low power consumption. All units activate together, ensuring comprehensive coverage. The 10-minute mute function provides convenience without compromising safety.
These alarms comply with EN 14604:2005/AC:2008 standards and feature low standby current (<50µA) and alarm current (<70mA). With a 10-year lifespan, they reduce ongoing costs and are ideal for B2B clients seeking scalable and dependable solutions.
We manufacture Interconnected Smoke Detectors with OEM/ODM support, custom branding, and packaging options. Automated production lines and strict quality testing guarantee consistent performance.
Our factory handles bulk orders, provides professional after-sales support, and offers technical guidance, making it ideal for large-scale installations and industrial projects.
These detectors are ideal for factories, warehouses, offices, hotels, and large residential complexes. The long-range 433MHz linking ensures complete coverage across multi-room or multi-floor areas. Ceiling or wall installation is flexible and straightforward.
