3.1 Siting and Positioning
The placement of gas detectors should be determined following the advice of:
•
experts having specialist knowledge of gas dispersion
•
experts having knowledge of the process plant system and equipment involved
•
safety personnel
•
engineering personnel
The agreement reached on the location of detectors should be recorded.
Guidance on the positioning of gas detectors to provide the best detection coverage is contained in IEC/EN 60079-29-2 and other
national Codes of Practice. It is recommended that the installation designer consults these Codes of Practice when determining
where detectors are to be located.
Additionally refer to the technical manual of the gas detector for siting recommendations specific for that device.
3.2 Mechanical Installation
The OELD can be mounted in a number of ways using the integral mounting tabs. The OELD can be attached to flat wall surfaces or
to Unistrut®. With the optional Pipe Mount kit, the unit can be mounted to pipe or pole. A ceiling mount bracket kit (1226A0358) is
also available. If required, conduit (either flexible or rigid) can be run to the OELD.
