INSTALLATION
 LPG,COandCH4Sensorsaredesignedtobewall-mounted(vertically),using
screwsandplasticplugs.Toproceedwithinstallation,openthecontainerby
unscrewingthescrewlocatedonthelowerside.Makesurenottodamagethe
sensorandnottotouchthecalibrationdevices.
POSITIONING
 Thecorrectinstallationoftheprobeisessentialtoproperoperationofthe
system.Therefore,itmustbeinstalled:
• Inareaswithcirculationofnaturalair;
• Inareasthatarenotsubjecttodustordirtthatmayrenderthesensor
inoperative;
• Nearjetsofwater,intakegrilles,openings,etc.
• Atanadequatedistancefromusersofgassoastopreventthesystemfrom
interveningimproperlyduetofunctionalleakage.
 Also,positioningdependsonthetypeofgastobedetected,specically:
• CH4 Sensor: Methane gas – at top, about 20-30 cm from the ceiling
• LPG Sensor: LPG – at bottom, about 20-30 cm from the floor
• CO Sensor: carbon monoxide – about 1.5 m from the floor
 Fornewsystems,theprobemustbeinstalledaslateaspossible,sothattypical
constructionsiteactivitiesdonotdamagethedetector.
CONNECTIONS
 Normalelectricalcablescanbeusedforconnections.Inanycase,when
installationisinplacesthatarestronglyexposedtoelectromagnetic
disturbances,itisadvisabletouseshieldedcables.Thedetectionsystemmust
alwaysbeinoperation.Therefore,theelectricalpowersupplyofthedetector
mustnotincludeswitchesorotherdevicesthatmayaccidentallyshutitoff.The
averagelifespanoftheprobesis5yearsfromthedateofinstallation.Therefore,
attheendofthattimetheywillneedtobereplaced.
Note. Make sure you check operation at least once a year, and in any
case whenever there is an extended period of disuse or in the event of
replacement. Any tampering may compromise correct operation of the
system.
