Location - Honeywell Sensepoint Technical Manual

Contact with aggressive substances may affect the performance of
these materials.
The detector is intended for use under normal industrial conditions
and must not be installed in an area where extreme vibration may
occur.
The enclosure has been tested to IP66 and with the cover fully
tightened down and the use of suitable cable entry devices will
maintain this protection under normal working conditions, however a
minimum protection of IP64 must be achieved.
This chapter provides the following information about installing Sensepoint:

Location

Honeywell can be installed indoors or outdoors.
The following sources give guidance when installing gas detectors:
• EN50073:1999 Guide for selection, installation, use and maintenance of apparatus for the
detection and measurement of combustible gases or oxygen
• International codes of practice
• specifications defining minimum gas detection requirements for specific applications
published by regulatory bodies
Mount the detector where gas is most likely to be present, noting the following points:
• for lighter-than-air gases mount the detector at a high level and preferably with the Collecting
Cone accessory fitted
• mount at a low level for heavier-than-air gases
• if installed outdoors always consider possible damage caused by natural events, e.g. rain or
flooding
• Ensure that a Weather Cover is fitted.
• ensure ease of access to the unit for commissioning and maintenance
• consider how escaping gas may behave due to natural or forced air currents
• check any associated process line conditions — gases may be normally heavier than air, but
if released from a process that is at an elevated temperature and/or under pressure, the gas
may rise rather than fall
• Document the agreed location of detectors
