5.1 Detector Mounting Details
To site the detector, find an unobstructed path, ideally above head height that covers the area to be monitored. When choosing the
beam path the direction of any prevailing air currents should be noted to assess the direction that any oil mist would be conveyed.
It should be noted that the beam must not be within 500 mm of any wall or partition. The operating range is 2 to 30 metres.
The reflector sheet must be mounted on a flat surface (self-adhesive backing) such that the detector and reflector are aligned
horizontally and vertically. To assist alignment a tool is available (Part No. 01-33-21) to ensure that the detector beam is aligned
correctly onto the reflector. The alignment tool makes it possible to visibly see the infra-red beam hitting the target reflector when
correctly alligned. Due to the nature of operation of the alignment tool, it is recommended that it should be used in subdued light
conditions. The physics of the reflector construction enable the reflector to be up to 10 Degrees out of alignment in any one plane
as detailed in the following diagram.
