CLOUD CHAMBER FIRE DETECTOR
ALMOST UNLIMITED APPLICATIONS
The ‘sensitivity range’ is the key feature
that makes the Cirrus Pro Series Fire
Detector the worlds most versatile fire
detection device.
High Sensitivity Applications include:Computer Rooms, Clean Rooms, Control
Rooms, Data Centres, Valve Halls, Archive
Storage, Anechoic Chambers, EDP areas.
For over 20 years Cloud Chamber detectors
have been known as the most sensitive
fire detection device, able to detect at the
true incipient stage of a developing fire.
General Sensitivity Applications include:Historic Buildings, Museums, Hospitals,
Cathedrals, Theatres, Art Galleries, Clean
Warehouses, Atria, Indoor Stadiums.
The New Cirrus Pro Series Detectors
have a vast sensitivity range capable of
being even more sensitive than previous
versions. In addition the detector may
now be configured to be installed in
heavily contaminated environments, such
as polluted production and warehousing
facilities.
