Siemens FDA2 Series User Manual

3 System description
Aspirating smoke detectors are used for early detection of smoke-generating fires
in rooms and equipment. They are particularly suited to applications in which point
detectors are pushed to their limits and cannot be used or can only be used with
restrictions.
The aspirating smoke detector continually removes air from the room being
monitored via a connected pipe system with defined aspirating holes. The air is
supplied to the detection chamber, where the built-in detector analyzes it for smoke
particles. The sensitivity of the detector can be adjusted.
The software 'FXS2056 ASD Asyst‑Tool V3' 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 up to 6700m²
● 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
Prerequisites for planning
To plan a successful pipe system, the following must be true:
● You are familiar with the local fire safety regulations and guidelines.
● A floorplan of the building where the pipe system is being installed is available.
You can see the following on the floorplan:
– Permanent fixtures
– Installed lights
– Electrical installations
– Gas and water pipes
● Information is available on the area to be monitored, especially in relation to the
fire loads that are present in the area.
● You know how to use the software 'FXS2056 ASD Asyst‑Tool V3'.
● You know how many fire sections are in the building concerned and how those
sections are split. Observe the local regulations and guidelines when splitting
fire sections again.
