The ANWETECH QRR3.0G/S-XR Hot Aerosol Fire Extinguishing Device is a compact, non-pressurized fixed fire suppression unit designed for rapid fire control in relatively enclosed protected spaces.
The device contains an aerosol-forming compound, cooling material, thermal activation component, electrical starter, internal cylinder and external housing. When activated, the extinguishing agent is rapidly generated and discharged into the protected area to suppress the fire.
The system is particularly suitable for locations where conventional water-based fire suppression may not be practical, including electrical cabinets, energy storage equipment, telecommunications systems, cable areas, machinery and vehicle compartments.
According to the source manual, the device is designed for fires involving Class A surface materials, Class B flammable liquids or meltable solids, Class C gases and energized electrical equipment.
The QRR3.0G/S-XR contains approximately 3 kg of aerosol fire-extinguishing agent.
With a specified extinguishing density of 100 g/m³, one unit has a nominal protected volume of 30 m³.
Unlike conventional cylinder-based gaseous suppression systems, the aerosol extinguishing device is stored without high-pressure gas.
The specified aerosol discharge time is ≤15 seconds, allowing rapid distribution of the extinguishing medium inside the protected enclosure.
Optional electrical activation allows integration with a compatible fire alarm or fire suppression control panel.
A thermal activation element can provide an additional method of initiating the extinguishing device.
The device can provide a switching feedback signal to the fire alarm / suppression control system after activation.
Suitable for demanding environments with an operating temperature range of:
-50°C to +95°C
Specified service life:
≥10 years
Suitable for mounting inside or near electrical cabinets, machinery compartments, energy storage cabinets and other enclosed equipment areas.

The manual provides these separation-temperature values for installation design.
The aerosol extinguishing unit can be connected to a compatible fire suppression control panel for automatic electrical activation and discharge feedback.
For the ANWETECH panel connection shown in the project wiring diagram:
ELECTRO VALVE + → START +
ELECTRO VALVE GND → START -
REL SWITCH GND → FEEDBACK 1
REL SWITCH + → FEEDBACK 2
Multiple aerosol extinguishing units can be connected according to the approved system design and control-panel output capacity.
The source manual states that the electrical starting terminals do not require polarity distinction, and that the feedback circuit is normally used only as a switching signal rather than for directly controlling high-power loads.
When the aerosol unit is integrated with a fire alarm / suppression system, the typical operating sequence is:
Fire Detection → Fire Alarm → Pre-discharge Delay → Equipment / Ventilation Shutdown → Aerosol Activation → Fire Suppression → Activation Feedback
After confirmed fire detection, the suppression controller sends an electrical activation signal to the aerosol unit.
The aerosol-forming compound is activated and rapidly generates the extinguishing aerosol.
The aerosol spreads throughout the protected enclosure and suppresses the fire.
The feedback contact changes state to indicate that the extinguishing device has operated.

These application types are specifically identified in the source manual.
For effective aerosol distribution:
The manual specifically requires a clear discharge path and a minimum 50 cm unobstructed area in front of the outlet.
Recommended inspection includes:
The source manual specifies monthly electrical and visual inspections and a service life of approximately 10 years when correctly installed and maintained.
It is not intended for normally occupied spaces under the source manual's application limitations. The manual also excludes certain reactive materials, active metals, self-decomposing chemicals, strong oxidizers and deep-seated Class A fires.
Personnel should not stand directly in front of the aerosol discharge outlet.
After activation, the protected area should be treated as a fire and suppression hazard area until appropriate ventilation and safety procedures have been completed.
