Frequently Asked Questions (FAQ)

How is the QRR series fire extinguishing device activated?

Depending on the model, activation methods include thermal detection line over-temperature activation (exceeding 170℃), logical multi-sensor activation (simultaneous >100℃ temperature and smoke detection), remote activation via software/cloud, or manual forced start by pressing the emergency button for 3 seconds.

Can the device be reused after it discharges?

Yes. The product features a two-segment modular structure. After a discharge event, the extinguishing cartridge can be easily replaced independently, allowing the device to be reused and significantly lowering maintenance costs.

What are the available installation options?

The device offers flexible mounting options to suit various environments, including industrial-grade 3M adhesive, high-strength magnetic adsorption, and secure screw fixation.

What are the differences between the MR1, MR2, MR3, and MR4 models?

The primary difference is the communication method: MR1 is a standalone unit without networking; MR2 supports RS485 wired connections; MR3 uses LoRa wireless connectivity; and MR4 is equipped with 4G wireless capabilities for direct cloud interaction and app management.

What size area can each unit protect?

The 0.1G/S unit is designed to protect spaces up to 1 m³, while the 0.3G/S unit protects enclosures up to 3 m³. The protected space should remain relatively sealed to ensure maximum fire suppression performance.
