Aspirating Smoke Detection System

SecuriRAS ASD 535, ASD 532 and ASD 531:- High-Precision Aspirating Smoke Detectors for Every Requirement.

Description:

SecuriRAS ASD 531 – Simple and Convenient for Smaller Premises

The ASD 531 offers quick commissioning and the highly professional monitoring of smaller areas and premises, and all without the need for training. The detector is configured directly on the device without the need for a PC and operation is uncomplicated. As with the two larger models, it is also equipped with the tried-and-tested HD detector with LVSC (large-volume smoke chamber). This results in outstanding sensitivity combined with an impressively long service life.

Applications: elevator shafts, electric distribution cabinets, false ceilings, small telecommunications

Containers, clean rooms, ventilation ducts, IT racks etc.

  • Compact design
  • Permissible temperature range: –10 °C to +55 °C
  • Maximum sampling pipe length: 75 m
  • Approvals: VdS, UL, FM, ActivFire, CCCF

SecuriRAS ASD 532 – The Compact Solution for Small to Medium-Sized Applications

The ASD 532 has a sampling tube length of up to 120 metres and works reliably at temperatures of between -30 °C and +60 °C. Thanks to its compact design, it is perfect for use in elevator shafts, prison cells, clean rooms, laboratories, IT racks, telecommunications facilities and many other applications. It has the same technical specifications as the more powerful ASD 535 model, but with just one sampling pipe and a more compact fan.

Applications: elevator shafts, prison cells, clean rooms, laboratories, IT racks, Telecommunications facilities etc.

  • Compact design
  • Permissible temperature range: –20 °C to +60 °C
  • Maximum sampling pipe length: 120 m
  • Ethernet or RS-485 networking
  • Approvals: VdS, UL, FM, ActivFire, CCCF

SecuriRAS ASD 535 – The Flagship Model for Large-Scale Applications

The ASD 535 aspirating smoke detector monitors large facilities with areas of up to 5,600 square metres. It is available with one or two sensors. Up to 400 metres of sampling pipe with a maximum of 120 sampling points in total can be connected to each sensor. With over 400 Pa of aspirating under pressure, the ASD 535 has one of the most powerful fans on the market. It is perfect for use in harsh environments, such as deep-freeze areas, explosion hazard areas or rooms with high levels of contamination. Thanks to the new “Config over Line” function, the detectors can be configured and serviced from the fire alarm control panel.

Applications: high-bay and deep-freeze warehouses, Ex zones, large data centres, Historic buildings, large halls etc.

  • Permissible temperature range: –30 °C to +60 °C
  • Immune to disturbances such as dust, dirt, moisture and steam
  • Reliable detection in difficult environments
  • Protection against false alarms
