RF-433 Interconnection Protocol
RF-Interlinked An Alternate Interconnect Safety Solutions for Homes
The VS01F utilizes the 433.92 MHz RF frequency to wirelessly connect with other alarms, forming a stable and interference-resistant network. Once any unit detects smoke or heat, all RF linked smoke alarms are activated simultaneously, ensuring fast and unified alerts throughout your home.
This RF smoke detector system operates independently of Wi-Fi, the internet, or a central hub. It provides a low-latency, high-reliability solution ideal for multi-room or multi-floor residences.
Key Features:
-RF Frequency: 433.92 MHz
-Synchronized alarm response across all connected units
-No dependence on Wi-Fi or gateways
-Suitable for homes, apartments, and small offices
-Battery operated interlinked smoke alarms, easy to install

Detection Technology
Reliable Smoke Detection with Infrared Scattering Technology
The VS01F uses infrared scattering technology (also known as photoelectric smoke detection) to detect smoke quickly. When smoke particles enter the sensing chamber, they scatter light from the LED (shown in blue). This scattered light is captured by a photosensitive receiver (shown in orange), and once the signal exceeds a preset threshold, the alarm is triggered.
This type of detection is especially sensitive to smoldering fires, offering early warning with fewer false alarms. It makes the VS01F a reliable choice among interlinked smoke detectors for home safety.

Detection Technology
Reliable Smoke Detection with Infrared Scattering Technology
When smoke enters the chamber, it scatters the infrared light emitted by the LED (shown in blue). This scattered light is then captured by a photosensitive receiver (shown in orange), creating a signal. If the signal exceeds a set threshold, the alarm is triggered immediately.
This method—known as photoelectric or optical smoke detection—is highly responsive to slow-burning, smoldering fires. It ensures early, accurate detection with fewer false alarms, providing better safety for homes and families.
