Aspirating Smoke 
Detector

Aspirating Smoke Detection (ASD) is one of the most advanced fire detection technologies available today, providing very early warning of incipient fires—long before smoke is visible or conventional detectors can react.

Key System Advantages

  • Active Air Sampling Technology: Actively draws air into the detector instead of waiting for smoke to rise, resulting in significantly faster identification of smouldering or incipient fires than conventional point detectors.
  • Ultra-High Sensitivity Detection: Detects smoke at levels as low as 0.002% obscuration/m, enabling action before fire escalation.
  • High Dynamic (HD) Smoke Sensor with Auto-Learning: HD sensor technology provides outstanding stability and long service life, featuring auto-learning, soiling compensation, and resistance to dust, moisture, and environmental drift.
  • Extremely Quiet Operation: 25–34 dB(A), ideal for data centers, hotels, museums, hospitals.
  • Flexible Integration: Supports Modbus TCP, RS-485, Ethernet, BMS systems, and fire alarm control panels.
  • Modular, Service-Friendly Design: The detector is fully modular, with replaceable filter, sensor, fan, airflow sensor, and main control board — minimizing downtime and simplifying maintenance.
  • Multi-Channel Capability: Up to 8 sampling channels via manifolds for accurate, zone-level smoke identification.
  • Robust in Harsh Conditions: Operates in extreme temperatures from –30°C to +60°C, depending on model.
  • High IP Protection: Standard IP54, with heavy-duty models up to IP66 for dusty or corrosive environments.
  • High-Pressure Aspiration Fan (up to 420 Pa): Powerful radial high-pressure fans support long pipe runs, large sampling networks, and stable airflow monitoring — ensuring reliable performance across large and complex facilities.
