For ‑SL variants, the fan voltage can also be set to 6.5V.
3.2 Areas of application
Thanks to their detection principle, FAS-420 aspirating smoke detectors represent an
extremely versatile fire protection solution.
Principle
Air samples are taken from the monitoring range by a pipe system with defined aspiration
borings and then fed to the detection module.
This is especially well-suited for areas in which point-type detectors cannot be used or can
only be used under certain circumstances. These include:
– Areas that are difficult to access, in which point detectors are difficult to install and
maintain
– Air-conditioned areas
– Areas that require the earliest detection possible
– Areas with a height greater than that allowed for point detectors
– Areas in which point detectors are not desired for aesthetic reasons
– Areas in which strong electromagnetic fields occur
– Areas that are exposed to high or low temperatures
– Areas with contaminated air that require filter elements
– Areas that must be protected against vandalism.
Space protection
The FAS-420 series is suitable for monitoring areas such as
– Those with double floors, false ceilings
– Tunnels, ducts, barely accessible hollow spaces
– Storage, high-rise warehouses, elevator shafts
– Museums, cultural institutions
– Hotel rooms, hospital rooms, offices, prison cells, train compartments
– Freezer storage
