Frequently Asked Questions
Q1: What is the difference between QRR-MR1 and QRR-MR4 models?
The QRR-MR1 is a standalone unit with no external communication, making it ideal for simple, self-contained installations. The QRR-MR4 supports 4G wireless connectivity and integrates with a cloud platform, enabling remote monitoring and control via a mobile app — suitable for multi-site or cross-regional management.
Q2: What types of fire hazards can the QRR MR series detect?
The QRR MR series simultaneously monitors wire temperature, ambient temperature, and smoke levels, providing comprehensive detection of electrical fire hazards before they escalate.
Q3: How is the QRR MR unit installed?
The unit supports three installation methods: 3M adhesive tape, strong magnetic adsorption, and screw fixation, offering flexible options for a wide range of environments and mounting surfaces.
Q4: Can the extinguishing cartridge be replaced after activation?
Yes. The two-segment modular design allows the extinguishing cartridge to be easily replaced after use. This enables the device to be reused, significantly reducing long-term operational costs.
Q5: What is the protected space volume for each agent size?
The 0.1G/S model (100g agent) protects spaces up to 1m³, while the 0.3G/S model (300g agent) covers spaces up to 3m³. The protected area should be relatively enclosed for optimal performance.
Q6: How long is the agent service life, and what are the operating environment requirements?
The extinguishing agent has a service life of 6 years. The device operates reliably in temperatures ranging from -40°C to +85°C and in humidity conditions below 95%RH, making it suitable for harsh industrial environments.
