FAS-420-TM Aspirating Smoke Detector
Airflow monitoring is temperature-compensated and can be set depending on the air
pressure.
Plug-and-play
The plug-and-play function makes the installation and commissioning of the aspirating smoke
detectors simple. The housing base is preinstalled on site. By preinstalling the detector
module for standard applications, the FAS-420-TM series Aspirating Smoke Detectors are
ready for operation as soon as they are inserted into the housing base.
Patented air sampling openings
The air sampling openings of the pipe system require clearly defined bore diameters that
depend on the planning and design. These precise air sampling openings are created using
patented aspiration reducing film sheets, marking tape, and clips, which not only permit easy
installation, but also prevent "whistling" noises. Another advantage is the quick and easy
detection and checking of the air sampling opening diameters.
Point-type detector projection
The system's aspiration points can be equated with point-type smoke detectors. The
monitoring areas can therefore be planned in accordance with the applicable national
regulations.
Diagnostics
A system with FAS-ASD-DIAG Diagnostic Software, which enables quick and convenient error
containment, is available for maintenance and service. The current and stored (max. 72 hours)
unit status is read out to the diagnostic appliance via the unit's infrared port. The data is
transmitted from the diagnostic appliance to a laptop via a USB cable.
Selecting the fan voltage
The fan voltage can be increased for special planning from 9 V to 12 V via the fire panel's
programming software. In addition, the fan voltage can be increased up to 13.5 V in intervals
of 1 V via the FAS-ASD-DIAG Diagnostic Software. The increase in the fan voltage causes an
increase in the air transport speed and therefore reduces detection time.
Extensive pipe accessories
The extensive range of accessories enables the FAS-420-TM aspirating smoke detectors to be
used even in the most difficult conditions. Products from air filters and condensate separators
to blowing-out systems increase the service life in extremely dusty, damp and cold
environmental conditions.
