The chime extender has special circuitry to reduce false triggers from most
commonhouseholdnoises.Thechimeextenderisdesignedtooptimizeits
responsetomid-frequencysoundwheremostmechanicaldoorbellsoperate
andtominimizeresponsetoextremelyloworhighfrequencysounds.Also,
thedesiredsoundmustbepresentcontinuouslyforatleast2seconds.
This design reduces the response to door slams, vibration, normal music
andtalking,etc.Loudcontinuousnoisessuchasyellingchildrenorvery
