RF-433 Interconnection Protocol
RF- Interlinked An Alternate Interconnect Safety Solutions for Homes
RF-interlinked smoke alarms utilize radio frequency (RF) communication to create a wireless network between multiple units. The VS-1 model operates on the 433.92 MHz frequency band, allowing stable and interference-resistant connections across devices within a typical residential range.
When any unit detects smoke and activates, all interconnected alarms respond simultaneously, providing synchronized, whole-home alerts. This system functions independently of Wi-Fi or central hubs, offering a low-latency, high-reliability solution suitable for multi-room or multi-floor environments.
Key Features:
– RF Frequency: 433.92 MHz
– Synchronized alarm triggering across all paired units – No dependency on Wi-Fi, internet, or central gateway – Optimized for robust performance in residential layouts

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.
