Frequently Asked Questions

Q What is the difference between the QRR MR1 and MR2 models?

The QRR□G/S-MR1 is a standalone unit with no external communication capability — it operates independently with integrated detection and extinguishing functions. The MR2 model supports RS485 wired communication, allowing it to be connected to a central fire alarm control panel for centralized monitoring in buildings or facilities.

Q Can the QRR MR series be monitored remotely via a mobile app?

Yes — the QRR□G/S-MR4 model supports 4G wireless communication and connects directly to a cloud platform. Users can monitor real-time data, view historical records, and perform remote control operations through a computer or mobile app from any location.

Q How does the QRR MR series detect fire hazards?

The QRR MR series simultaneously monitors wire temperature, ambient temperature, and smoke in real time. It uses logical activation when temperature exceeds 100℃ and smoke is detected at the same time, providing multi-sensor verification to prevent false alarms and ensure reliable fire hazard detection.

Q What is the service life of the extinguishing agent, and can the cartridge be replaced?

The extinguishing agent has a service life of 6 years. The QRR MR series features a two-segment modular design, which means the extinguishing cartridge can be easily replaced after use. This design allows the device to be reused, significantly reducing long-term operational and maintenance costs.

Q What installation methods are available for the QRR MR series?

The QRR MR series supports three flexible installation methods: 3M adhesive tape, strong magnetic adsorption, and screw fixation. This versatility makes it suitable for a wide range of installation environments and surfaces.

Q Which model is best suited for locations where wiring is difficult or impractical?

The QRR□G/S-MR3 with LoRa wireless communication is ideal for areas with distributed layouts or locations where running cables is difficult or costly. It provides long-range wireless connectivity with flexible installation and low network setup costs, making it perfect for remote or hard-to-wire environments.
