The FAS-420 Aspirating Smoke Detector can be used for early fire detection in areas with
special-purpose air conditioning.
Thanks to its high sensitivity, expensive goods and equipment can be monitored reliably. The
aspirating smoke detectors from the FAS-420 series are therefore especially suitable for areas
of application:
– Where early intervention is essential due to a high value concentration
– Where equipment must always be operational
– Where highly sensitive detection is necessary (e.g. in areas where, due to built-in filter
elements, the air contains a low concentration of smoke particles)
– Where high air-exchange rates prevail.
Equipment protection
Equipment monitoring involves the direct monitoring of an object. These can be unventilated
or force-cooled units or cabinets, e.g.
– Distributor cabinets, switching cabinets
– Telephone-switching equipment
– Measuring, control, and regulation equipment.
