In Dubai’s 2024 fire safety audit, 58% of smoke alarm failures in industrial zones were traced to dust accumulation in sensor chambers – causing false alarms or deadly silence.  Hangzhou Deheng Smart Electric company located in Zhejiang Province, is an advanced EN 14604 dustproof alarm supplier in China. The R&D team in Deheng wants to share some industrial information with our audience.

Dust particles:

• Scatter light in photoelectric sensors, triggering false alerts
• Clog ionization chambers, reducing sensitivity to real smoke
• Attract moisture, accelerating corrosion in humid climates

The Deheng Difference: TÜV-Validated Sealing (No Compromises)

Core Technology: IP42 Certified Sealed Chambers

• Test Standard: IEC 60529 (IP42 = Protection against 1mm+ solids)
• Validation Body: TÜV Rheinland (Report# FK768392)
• Sealing Method: Laser-welded housing + silicone gaskets

How It Works:

1. Barrier Defense:
• Blocks dust/sand >1mm via precision-engineered seams
• Nano-mesh vents (78μm pores) trap fine particulates while permitting smoke entry
2. Zero Internal Contamination:
• Sealed optical chamber prevents dust adhesion to sensors
• No internal fans or moving parts to attract particles

Where This Matters: Install with Confidence

1. Arid Climates (GCC, Australia):
• Withstands sandstorms without false alarms
2. Industrial Zones:
• Immune to workshop dust (wood, metal, textile)
3. Renovation Sites:
• Survives plaster/concrete dust exposure

Maintenance Protocol (TÜV Recommendations)

1. Surface Cleaning Only:
• Vacuum external vents quarterly with soft brush
• Never open housing or use compressed air
2. 10-Year Replacement:
• End-of-life beep ensures integrity
