Aerosol Fire Extinguishing Device User Manual

I. Overview
The small aerosol fire extinguishing system is a new environmentally friendly fire protection product with world-leading technology. It is a new high-tech green firefighting product further developed on the basis of the third-generation S-type aerosol.

1、Product Features

(1) Eco-friendly Product: Excellent cleanliness, with an ozone depletion potential (ODP) of 0 and a global warming potential (GWP) of 0.
(2) Stainless Steel and Aluminum Alloy Cylinders: Corrosion-resistant, stored at normal pressure, leak-proof, and low maintenance.
(3) Certification: Passed fire extinguishing tests and certification by the National Fixed Firefighting Systems and Fire-resistant Components Quality Supervision and Inspection Center.
(4) No Residue After Extinguishing: Releases aerosol particles smaller than 2 microns after activation, which disperse easily in the air. The particulate matter released is even less than the dust that naturally settles in a closed computer room over a month.
(5) Compact Size: Reduces the size and weight by up to 90% compared to other fire extinguishing systems, not occupying space in the protected area.
(6) Easy Installation: No need for high-pressure containers or complex piping networks, saving space and installation costs.
(7) Convenient Design with Wide Applicability.
(8) Long Agent Shelf Life: The agent lasts for up to 10 years, which is better than other types of fire extinguishing agents.

2、The small aerosol series fire extinguishing systems are suitable for fighting the following types of fires:

1. Construction Industry: High-rise buildings, industrial buildings' transformer and distribution rooms, libraries, archives, underground storage rooms, safes;
2. Telecommunications Industry: Telecom rooms, computer rooms, communication base stations, relay stations, data processing rooms in distribution cabinets, remote control rooms, precision equipment distribution cabinets;

Small Aerosol Series Fire Extinguishing System Model Numbering and Types

(1) Basic Model:

（2）Numbering method:

For example: QRRO.25GW/S-E-WK represents a 250g suspended temperature-limited model with single electric activation, without feedback signal.

(3) Operating Environment Requirements

Temperature Range: -50℃ to +90℃
Relative Humidity: ≤95%RH

Ⅱ、 Working Principle

E (Electric Activation) Model Operating Principle: The fire alarm controller or gas fire extinguishing control detects the fire signal. When a fire is detected, it outputs a start signal to the small aerosol series fire extinguishing device. After receiving the start signal, the fire extinguishing agent inside the device is activated, rapidly generating nano-sized aerosol fire extinguishing agents, which are then sprayed out for quick fire suppression.

2） TH (Thermocouple Activation) Model Operating Principle: When the ambient temperature reaches the activation temperature of the thermosensitive wire in the small aerosol series fire extinguishing device or when the thermosensitive wire comes into contact with open flames, it is activated to start the fire extinguishing device. The device rapidly generates nano-sized aerosol fire extinguishing agents and sprays them out for quick fire suppression.

3） ST (Striking Activation) Model Operating Principle: When the ambient temperature reaches the activation temperature of the temperature-sensing element in the small aerosol series fire extinguishing device, the element is activated to start the fire extinguishing device. The device rapidly generates nano-sized aerosol fire extinguishing agents and sprays them out for quick fire suppression.

4） Wiring Instructions: The red and blue wires are the activation wires, and the black wire is for feedback.

Mechanical Temperature-Sensitive Magnetic Generator Activation Model Operating Principle: When the small aerosol series fire extinguishing device reaches the activation temperature, the fusible alloy melts and falls, generating an electrical pulse start signal to activate the fire extinguishing device. At the same time, it can transmit the activation signal to the monitoring host, outputting the start feedback signal. Once activated, the device rapidly generates nano-sized aerosol fire extinguishing agents and sprays them out for quick fire suppression.

Wiring Instructions:

The first type of mechanical temperature-sensitive magnetic generator activation element base has 4 terminals in the center. The terminals marked with “+” and “-” are for connecting the activation power supply wires. The two middle terminals are for the activation feedback output. The feedback device remains open at normal temperature, with a resistance greater than 100MΩ.
The second type of mechanical temperature-sensitive magnetic generator activation element base has 4 terminals in two colors. The blue terminal is for connecting the activation power supply wires, and the green terminal is for the activation feedback output. The feedback device remains open at normal temperature, with a resistance greater than 100MΩ.
