200 Gas Detector Manual – TM 792100, Rev. D, May 2004

The open path between the Source and Detector and the immediate
surroundings should be kept clear of obscuration that might hinder the free
movement of air in the protected area or block the infrared beam.

5.2.5 Guidance Tips for Gas Detector Locations

Guidance Tips for Gas Detector locations in order to provide the best detection
coverage:

1. Below potential leak source for heavier than air gases
2. Above potential leak sources for lighter than air gases
3. Near to leak sources along the expected leak trajectory, taking into

account prevailing wind directions

4. Between leak source and potential ignition sources
5. In area with expected heavy fog, rain or snow, consider the effect of long-

range installation and install the detector at shorter range with the
maximum intensity model available.

5.3 Preparations for Installation

1. Upon receipt, verify the appropriate Purchase Order and record the Part

Number and Serial Number of the Source and Detector units in the
appropriate Log Book.

2. Carefully unpack the following equipment observing any instructions

printed on or contained in the packaging list. Check the contents for any
possible damage caused from shipping and handling. In the event of
damage or loss in transit, notify the carrier and your Supplier immediately.

The System should include the following (in addition to this manual):

•

Detector unit

•

Source unit

•

Two tilt or swivel Mounting Bases – one for the Detector and one for the
Flash Source.

•

Telescope Kit

•

Functional Filter

•

Magnetic Mode Selector

Notes:
1

The Magnetic Mode Selector, the Calibration Filter and the Telescope Kit are
used during each SafEye’s installation and then removed. They can be
reused for all other SafEye installations on the site. Therefore, only one set
is provided for several detectors.

There are two different Telescope Kits:

For standard installation

P/N 794110

For Duct installation

P/N 794245

There are two different types of Functional Filter. One for standard mount
and the other for Duct Mount. Each type has five different models for
different gas reading.

For standard installation

P/N 794260 - 1 to 5

For Duct installation

P/N 794220 - 1 to 5
