120 dB ?  NOT !!
I would rate this alarm similar to your doorbell buzzer. . . if that.  As a caregiver, if you fall asleep and the patient gets out of bed, triggering the alarm, it may only wake you if you are in the same room, and a light sleeper.  It is not loud enough to wake you, and shouldn't be counted on if the alerted response is mandatory.  It would be fine to use if you are awake and in an adjacent room to the patient.  The manufacturer's claim of 120 decibels is utterly ridiculous!  120 decibels is ear-splitting.  It is like sitting in the front row of a rock concert. . . you could not hear yourself talk.  I like everything else about this unit.
