3. INSTALLATION AND OPERATION
Below this temperature, snow or ice blown onto the window will not be melted until the ambient
temperature rises. If long-term, outdoor operation in very cold climates is intended, it is
recommended that extra shielding/covers are employed to prevent snow/ice from being blown
onto the windows and building up.
Note: The heated optics have not been evaluated as part of the performance testing relating
to the FM approval and therefore are not considered part of the performance approval.
Deluge and Flooding - Searchline Excel is rated IP66/67 and as such will not be damaged
byoccasionaldelugeorooding.However,duringsuchinstancestheunitwillcompletelylose
itsIR signal and willenter the BEAM-BLOCK/FAULTstate.Also, whenthe deluge/ooding
subsides, there is the possibility that contaminants will be left on the windows. Therefore, it
is recommended that Excel units be located away from areas particularly prone to deluge or
ooding.
Areas Prone to Subsidence and Settling - Where possible, it is recommended that Excel units
are not mounted on structures located where problems with subsidence, settling or thawing
ofpermafrostareknowntocausesignicantmovement.Ifsuchlocationscannotbeavoided,
the foundations of the mounting structure should be engineered to minimise any angular
movements.
Areas Prone to Earthquakes - In locations prone to earthquakes, there is a chance that during
or after an earthquake, the units of an Excel gas detector will become misaligned with respect
to each other. Provided that the Excel units do not suffer from direct mechanical impact damage
during an earthquake, they should remain undamaged by such events. Anti-vibration mounts are
unlikelytobeofanybenetandarenotrecommended.Afteranearthquakeitisrecommended
that Excel gas detectors are visited and their alignment be checked.
Accidental Impact - Locations wherethereisasignicantlikelihoodofequipment,personnel
or moving objects accidentally knocking Excel units out of alignment should where possible
be avoided. If such locations cannot be avoided, measures including improved mechanical
protection and warning notices should be considered.
Intense Electromagnetic Fields - Searchline Excel complies with EN61000-6-3:2007 and
EN61000-6-2:2005 (Industrial levels) and as such is well protected from interference by
electromagneticelds.However,locationsincloseproximitytoradio/radartransmitters,heavy
electricalplantandhighvoltagepowercablesmayexperienceeldstrengthsinexcessofthose
speciedinEN61000-6-3:2007 and EN61000-6-2:2005. Where possible, such locations should
be avoided or units should be installed as far as possible from the source of the electromagnetic
eld.Measuresincludingadditionalscreening,lteringandtransientsuppressionmayalsobe
ofbenetinsuchlocations.
3.2.3 Beam Path
The Transmitter and Receiver units windows should face each other across the area to be
protected and, depending on the range of the Transmitter in use, should be the following
distance apart:
