Using aspirating smoke detectors

Aspirating smoke detectors are used for early detection of smoke-generating fires in rooms and equipment. They are suited to applications in which point detectors are pushed to their limits, cannot be used or can only be used with restrictions.

The aspirating smoke detector continually removes air from the room being monitored through the connected pipe systems via defined aspirating holes. The air is supplied to the detection chambers, where detectors analyze it for smoke particles. The sensitivity of the detectors can be adjusted.

The 'FXS2056 ASD Asyst‑Tool V3' software calculates the position and size of the aspirating holes. The calculation ensures that the air passes from the aspirating hole to the detector in the time specified and with the calculated sensitivity.

Examples of use

  • Cavities such as false ceilings or false floors
  • Clean rooms
  • Rooms the height of which is greater than that permitted for point detectors
  • Rooms with electromagnetic fields which influence the function of point detectors
  • Large rooms such as storehouses or factory halls
  • Separate monitoring of control cabinets and electronics cabinets
  • Data centers
  • Telecommunication centers
  • Assembly lines
  • Cable tunnels
  • Conveyor belts

Applications with a filter box

  • Rooms with polluted air in which the pollution has impaired the performance of optical point detectors
  • Assembly lines
  • Recycling facilities
  • Cement factories
  • Mining industry
  • Subway stations
  • Agricultural operations
  • All other applications with visible dust load
