Dear Rishabh,
Determine EDLM locations: Use the site survey to mark the required locations of
the EDLMs. The following guidelines will help determine the number and location of the EDLMs required:
Length and width: EDLMs should be arranged in a grid fashion along the width and length of the area so that the area is reasonably covered, with EDML locations every 5-10 metres.
The chosen sensor grid should take account of:
• The layout of the area (e.g., whether it is square or includes alcoves).
• The degree to which shelving and products may affect airflow.
• Where products are placed. The positions of EDLMs should coincide with locations where TTSPs are actually stored or planned to be stored. For example, it may be unnecessary to fit EDLMs in areas such as the upper part of high loading bays.
• Other considerations that may warrant more or fewer EDLMs.
Height: At each point on the grid, arrange EDLMs vertically as follows:
• If the ceiling height is 3.6 metres or less, position EDLMs directly above one
another at high and low level (e.g. one EDLM at floor level, 1.2 metres and one
EDLM at 3.0 metres.
• If the ceiling height is greater than 3.6 metres, arrange EDLMs in vertical arrays at
the bottom, middle and top of the space. For instance, for a storage area six metres
in height, three EDMLs should be positioned in each grid location heights of 1.8
metres, 3.6 metres and 5.4 metres.
Give each logger location a unique ID. It may be helpful to use a generic floor plan or diagram to decide where each logger should be positioned.
