Nexisense G003 Explosion-Proof Sound and Light Alarm: Integrated Solution for High-Risk Areas

In high-risk industrial scenarios such as oil & chemical, metallurgy, and pharmaceutical industries, combustible gas leaks, abnormal oxygen levels, or toxic gas dispersion can cause catastrophic accidents. Traditional single-alarm modes (e.g., sound only or light only) are prone to failure due to environmental noise, visual interference, or equipment faults. The Nexisense G003 area explosion-proof sound and light alarm combines explosion-proof structure, sound-light linkage, and multi-protocol compatibility, providing a highly reliable and low-maintenance solution for high-risk areas.

1. Application Scenarios: Covering IIC High-Risk Gas Environments and Zones 1/2

1.1 Core Industries

• Pharmaceutical & Semiconductor: organic solvent storage, process gas delivery systems

• Energy & Power: gas turbine rooms, LNG receiving stations, biogas power plants

  
  

1.2 Typical Scenario Requirements

• Explosive gas environment: must meet IIC explosion-proof requirements (e.g., hydrogen, acetylene), applicable for zones 0, 1, 2

• Complex environment adaptability: high humidity (0~99%RH), corrosive gases, extreme temperatures (-40℃~60℃)

• Multi-system linkage: seamless integration with Fire Alarm System (FAS), Gas Detection System (GDS), and industrial process control (DCS)

2. Technical Architecture: Explosion-Proof Structure with Sound and Light Linkage

2.1 Explosion-Proof Performance: Flameproof Design + IP66 Protection

• Housing: high-strength aluminum alloy explosion-proof shell, IK10 impact resistance; lampshade made of imported PC + tempered glass, transmittance ≥90%

• Internal Circuit: intrinsically safe design, component spacing ≥3mm to prevent sparks

• Protection Rating: IP66 (dust & water-proof), suitable for harsh outdoor environments, reducing maintenance frequency

2.2 Sound-Light Linkage: Dual Alerts for Improved Response

• Sound Alarm:

• Sound pressure: 110dB~120dB@1m (adjustable), penetrates industrial noise (e.g., compressors, fans)

• Sound modes: ≥10 options (continuous, intermittent), adjustable volume 60dB~120dB

• Light Alarm:

• Luminous intensity: 100~600cd (IEC 60079-28 compliant), red LED, flash frequency 75~180 times/min

• Display modes: rotation or flashing, suitable for different visibility distances (long-range rotation, short-range flash)

  
  

2.3 System Compatibility: Multi-Protocol Support & Centralized Monitoring

• Input protocols: 4-20mA, RS485, Modbus RTU/TCP, HART; compatible with catalytic, infrared, electrochemical detectors

• Output protocols: connect to FAS/GDS/DCS for interlock control (e.g., valve shutoff, ventilation startup)

• Scalability: cascade deployment, one controller can manage up to 64 alarms for regional hierarchical warning

3. Selection Guide: Configurations Matching Scenario Requirements

• Explosion-proof level & zone classification:

• Gas group: IIC (H2, C2H2), IIB (C2H4, coal gas), IIA (C3H8, CH4)

• Zones: 0 (continuous), 1 (frequent), 2 (occasional)

• Sound & light parameters:

• Sound level: indoor noise ≤85dB → ≥90dB; outdoor noise ≥85dB → ≥110dB

• Light: long-distance warning (>50m) red LED ≥300cd; multi-device auxiliary colors (yellow: warning, blue: fault, green: normal)

• Environmental adaptability:

• Temperature: -40℃~60℃ for cold regions; IP66 & anti-condensation for tropical high-humidity areas

• Corrosive gases: 316L stainless steel shell or epoxy coating recommended

4. Integration Considerations: Ensure Stable Operation

• Installation:

• Height: 2.5~3m; lampshade tilt ≤15°

• Wiring: separate power & signal channels ≥150mm; explosion-proof flexible conduits, bending radius ≥5×pipe diameter

• Calibration & Testing:

• Sound test: verify dB at 1m, tolerance ≤±3dB

• Light test: measure luminous intensity in darkroom

• Linkage test: simulate gas leak, response time ≤2s

• Maintenance:

• Quarterly lampshade cleaning & check explosion-proof joints

• LED lifetime ≥50,000 hours; buzzer ≥100,000 triggers

5. OEM/Customization & Bulk Supply Advantages

• Flexible customization: alarm logic, wireless modules (LoRa/NB-IoT), appearance, private protocol adaptation

• Bulk supply: monthly output >10,000 units, ISO 9001, ATEX, IECEx certified, full traceability

• After-sales: 3-year warranty, 72-hour on-site response
