This is a second receiver for the Malem Wireless Bedwetting Alarm. This receiver is the part of the alarm that generates the sound used to awaken your child. Once urine is detected by the transmitter, this receiver will sound until the reset button is pressed. This helps ensure that your child will wake to the sound of the alarm.
To help ensure your child will wake up to the sound of the alarm, this receiver offers the choice of 8 random sounds (or you can choose to use the same sound each night) so your child won't become accustomed to the sound of the alarm and sleep through it.
