4.4 Capability to Critical Enviroments
4.4.1 High Air Velocity
High air movement does not have as great as an effect on Optical Beam Smoke Detectors as other
detector types. An Optical Beam Smoke Detector’s sensing range can be long as a football field
(maximum beam range is typically 100 metres). It is therefore less likely to blown out of the Optical
Beam Smoke Detector’s sensing range. Although reduced spacing is not required in high airflow
areas, attention should be given to the anticipated behaviour of smoke in these applications.
4.4.2 Hostile Enviroment
Optical Beam Smoke Detectors are not as limited as point type detectors to hostile environments:
temperature extremes, dirt and corrosive gases and such.
In addition, flame / explosion proof Optical Beam Smoke Detector have been designed for protection
of large hazardous (with potentially explosive atmospheres) areas, such as:
 Refineries
 Mills

Munitions Factories and Stores
 Flammable Liquid Stores
 Flammable Gas Sores

Flammable Powder Stores
 Industrial Plants and Warehouses
 Power Stations
This version provides an early warning of smouldering or strongly smoke generative fires, which may
not be picked up by flame detectors installed in these hazardous areas.
Flame / explosion proof Optical Beam Smoke Detectors are ATEX approved.
