FUNCTIONING
Afterhavingturnedthedetectoronwiththefrontbutton(ref.2),thesensor'sheatingprocedurelastsfor
about90secondsandisindicatedbytheyellowled .(ref.3)
Attheendoftheheatingprocedure,thedetectorisreadytosignalanyalarmingsituation. Theoperating
modeisindicatedbytheflashingoftheyellow(ref.3)(1flashevery2seconds).
Whenthegasconcentrationexceedsthelimitestablished,theacoustic(buzzerwithintermittentsound)
andvisual(yellowledalwayson)alarmstartsfunctioning.
Thealarmcontinuestooperateuntilthedetectoristurnedoff.
