5.2.5 Tips for Selecting a Gas Detector Location
The following are some tips for selecting gas detector locations, in order to
provide the best detection coverage:
 For heavier-than-air gases: below potential leak sources.
 For lighter-than-air gases: above potential leak sources.
 Along the expected leak trajectory: near leak sources, considering
prevailing wind directions.
 Between leak source and potential ignition sources.
 In areas with expected heavy fog, rain, or snow, consider the effect of
long-range installation and install the detector at a shorter range with
the maximum intensity model available.
Preparations for Installation 5.3
Installation should comply with local, national, and international regulations
and norms, as applicable to gas detectors and approved electrical devices
installed in hazardous areas. The detectors can be installed with general-
purpose common tools and equipment.
In addition to this manual, the system should include the following:
 Detector unit: XDSS-X-11XXX (See Models and Types, page 22).
 Source unit: XSS-X-1XX (See Models and Types, page 22).
 Two Tilt Mount Bases P/N 799640.
 One base is used for the detector
 One base is used for the flash source
 The commissioning kit includes function check filter and the telescope
kit, which is used during each SafEye installation and then removed.
They can be reused for all other SafEye installations on the site.
Therefore, only 1 set is provided for several detectors.
 Telescope Kit P/N 799210.
 Function Check Filter P/N 792260 (1–5). There are 5 options depending
on full scale and type of calibrated gas.
