Areas of Application
Thanks to their detection principle, FAS-420-TM 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 detector 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-TM 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
Area monitoring with air-conditioning
Area monitoring occurs
–
In rooms with air-conditioning for service rooms etc.
–
In ventilation ducts
–
In double floors, false ceilings
–
In IT rooms, e-distributor rooms, transformer cells
