4.5 Field of View Restrictor
There are some unique and specialized applications that may require a restricted field of view in order to
prevent the Detector from alarming to a known (friendly) fire/flame source (such as a flare stack). The Model
FVR-01 Field-of-View Restrictor is easily modified in the field with a simple hack saw to obtain custom
Detector field-of-views for applications where specific narrow field-of-views are required. The Model FVR-01
Detector accessory has been developed specifically for these unique types of applications. Use of the
restrictor has not been certified to the EN54-10 standard.
