The individual places the sensor (usually located in briefs or underwear) and turns the alarm device on (there are various types of alarms) before going to sleep. The enuresis alarm is triggered when a sensor in the sheets or night clothes becomes wet with urine, setting off an auditory signal with the intention of causing the individual to wake, cease voiding, and arise to void. Parents are advised to wake their child when the alarm is activated—otherwise, children are prone to turn it off and go back to sleep.[3]
