TheMOS-21sensormonitorsmoonininteriorspaces.Thesensorispowered
by solar energy from natural or arcial light sources. The solar energy is
transformedintoelectricalenergywhichisthenstoredprovidingaconnuous
powersourceforthesensor.Poweredbysixsolarcells,thesensorcanoperate
withoutbaerybackupforupto225hours.Thesensorwilloperateevenwitha
briefexposuretolight,howeverforbestresultsthesensorshouldbemounted
inalocaonwithexposurefor2hoursofnaturalorarciallight(160-500lux
or16-50fc)onadailybasis.
Abaery(CR2032)mustbeinstalledintheMOS-21xC sensor for use in high
bayapplicaons.
ThemoonsensorsupportstheOccupancySensorEnOceanproleA5-07-01.
The sensor will transmit occupancy or vacancy depending on the occupancy
state of the room. The sensor will broadcast occupancy immediately upon a
statechangefromvacanttooccupied.Thesensorbroadcastsatelegramwhen
movement is detected and repeats occupied telegrams with a minimum 100
secondperiodbetweensubsequenttransmissions.
Aer detecng moon, the sensor is shut-down to conserve energy for
100 seconds. When the sensor awakens and no moon is detected, the
sensor transmits a vacancy telegram aer 100 seconds, 200 seconds total
since the previous transmission. The sensor will remain acve unl the next
occupancystate.Ifthesensordoesnotdetectmoon,itresendsthevacancy
telegramevery1000seconds.
Thesensormustbewithinrangeofanylinkedreceiversorcontrollers,installed
within 24m (80’) of each other. For applicaons exceeding 24m (80’) range,

TheMOSfamilyusesaPIRsensorthatdetectsmoonbymeasuringtheinfrared
energygivenobyobjects.Thesensoriscalibratedtodetecttheheatrangeof
humanbodytemperature.Thesensorhasalensthatbreakstheviewingangle
ofthesensorintozones(movementzones).Itisthemovementoftheinfrared
energy moving in and out of a zone that denes occupancy. The amount of
movementthattriggersthesensorisdependentuponthedensityofthezones
wherethemoontakesplace.Ahigherdensityofzonesmeanssmallermoon
willtriggerthesensor.
Fordeteconofsmallmoon(typing,drinkingfromacoeecup),usetheMOS-
21Amodelwhichhasalenswithmoremovementzones.Placethesensorclose
tothelocaonwherethemoonmayoccur.
AredLEDunderthelenswillblinkonce every 100 seconds when the sensor
