4.1.1 Line of sight
In order for the flame detector to detect a fire, the fire's infrared radiation must
reach the flame detector. The infrared radiation can reach the detector through
direct or indirect irradiation.
Direct irradiation:
Indirect irradiation from reflections on walls, equipment etc.:
Direct irradiation is many times higher than indirect irradiation. The flame detector
should therefore be positioned such that it has as direct a line of sight as possible
to the entire monitoring area.
Glass and synthetic materials reduce infrared radiation so much that perfect
detection is no longer possible. Avoid glass and synthetic materials between the
flame detector and area being monitored.
