“The Safety Sentinel” – Leading the Way in North America

For consecutive years, this safety guardian has remained the No.1 choice in the North American market. With the rapid development of AI, IoT, and Big Data, living standards are rising, safety awareness is stronger than ever, and demand for smart security solutions is accelerating. The smart security market is expected to exceed RMB 1 trillion by 2020, as systems evolve from digitalization and networking to full intelligence.

Smart Smoke Alarm Systems

At the forefront of this transformation, smart smoke alarm systems are growing rapidly. These systems integrate smoke sensors, function keys, and audio-visual alarm devices, all connected to intelligent platforms for real-time monitoring and automatic fire alerts.

When smoke is detected, the built-in MCU measures concentration via infrared light and circuit changes to determine a fire risk. Once confirmed, the detector activates a fire signal, lights the red indicator, and triggers the buzzer alarm—urging people to evacuate and automatically sending data to the smart fire monitoring platform.

The Role of Buzzers – The Core of Safety

Buzzers serve as the core sounder in smart smoke alarm systems. Reliable and efficient, they are the first line of defense in fire safety alerts. Beyond smoke detectors, buzzers are also widely used in anti-theft alarms, equipment alerts, and home security devices—truly a “safety sentinel” in everyday life.
