The Astec-Duo (Silent) air sampling smoke detector is an extremely cost-effective solution for monitoring a broad range of applications and environments.

The high degree of modularity makes it possible to quickly and efficiently provide air sampling smoke detection over large open spaces, voids, warehouses and many other diverse environments.

The silent version of the Astec-Duo air sampling smoke detector has a quieter aspirator than the standard version, making it suitable for noise-sensitive applications.

The detector is a true two zone, twin pipe system that can be used to replace up to 64 ‘point type’ smoke detectors with up to 560m of air sampling pipe, regardless of whether Class A, B or C is required in accordance with EN54-20.

Two separate detector modules are incorporated within the detector providing separate indications and outputs for each pipe.

  • Silent version, from 23 dB(A), for noise-sensitive environments.
  • Early fire detection thanks to innovative, highly sensitive HPLS light source technology.
  • A high degree of false alarm immunity through LOGIC·SENS fire pattern recognition.
  • Time-saving commissioning through Plug & Play, no additional PC interface or dedicated programmer required.
  • Simple installation and commissioning due to the modular concept of the Astec-Duo.
  • Reliable project design with EN54 certification.
  • Simple Fire & Fault indication with volt free relay outputs, per pipe, for connection to addressable or conventional fire alarm control equipment.
  • Two separate detector modules provide separate indications and outputs.
  • Fully compatible with inline filtration and blow through systems for harsh environments.
  • Compatible with a wide range of Astec ASD add-ons for feature-rich expansion.
