An RF-Linked Intelligence for Every Room

Smart Detection. Synchronized Response.

The VS01F RF Smoke Alarm and VH01 Heat Alarm work together to detect multiple types of fire threats, enabling synchronized alerts across all connected units. This RF interlinked smoke alarm system delivers comprehensive home protection without the need for complex wiring or internet connection.

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.

Frequently Asked Questions of MS-1

  • What is an RF interlinked smoke alarm?

    An RF interlinked smoke alarm uses radio frequency to wirelessly connect with other alarms in your home. When one alarm detects smoke, all connected units sound simultaneously to provide whole-home protection—without needing Wi-Fi or a central hub.

  • Are RF smoke detectors better than Wi-Fi smoke alarms?

    RF smoke detectors offer reliable, low-latency performance without dependency on internet connectivity. This makes them ideal for environments where stable wireless interconnection is critical and where Wi-Fi may be unreliable.

  • Can I use RF interlinked smoke alarms in multi-story houses?

    Yes, these systems are optimized for multi-floor and multi-room layouts. The 433.92 MHz frequency provides stable signal transmission throughout most residential homes.

  • Are RF smoke alarms easy to install?

    Absolutely. These are battery-operated interlinked smoke alarms that require no wiring, Wi-Fi setup, or mobile app. You simply pair them during setup, and they’re ready to go.

  • What type of fires do these RF smoke detectors detect?

    They use photoelectric infrared scattering technology to detect slow-burning, smoldering fires—common in home environments—and are highly effective with fewer false alarms.

  • Are interlinked smoke alarms worth it?

    Yes. Interlinked smoke alarms provide whole-home protection—when one alarm detects smoke, all connected alarms sound. This ensures faster alerts across different rooms and floors, giving you more time to react.

  • What are the pros and cons of wireless smoke detectors?

    Pros: Easy installation (no wiring), flexible placement, reliable whole-home alerts, and portability.

    Cons: They require batteries, can have limited range depending on house size/walls, and may need manual re-pairing if reset.

  • How long do interconnected smoke alarms last?

    Most interconnected smoke alarms last around 8–10 years, depending on the sensor type and battery design. After that, both the alarm unit and sensor should be replaced to maintain safety.

  • Can I mix smoke and heat detectors in an RF interlinked system?

    Yes. Many RF systems allow a combination of smoke alarms and heat detectors, so when one device is triggered, all units in the system will sound.

  • Are RF smoke alarms safe from interference?

    Yes. They typically operate on the 433 MHz band, which is reliable for short-range communication and designed to minimize interference in residential environments.
