Nite Train-R Bed-wetting Alarm Review

The Nite Train-R Bed-wetting alarm is perhaps one of the oldest bed-wetting alarms still available today.  It consists of an alarm box and a sensor pad with cable that is gender-specific for boys and girls.  Because of its longevity, it is probably the bed-wetting alarm most people imagine when they think of alarms to help with bed-wetting.  The only other type of alarm so commonly associated with bed-wetting are the moisture pad that goes on the bed, which the makers also produce.

The Nite Train-R alarm uses sensors based on whether the bed-wetting child is male or female.  Both types of sensors consist of a foam insert with holes that connect to the sensor pad.  When moisture is detected, the pad sounds an alarm, worn on the child’s shirt, that wakes the child up.

Because the alarm uses an insert sensor, it cannot be worn with boxer shorts, instead the alarm must be worn with brief style underwear:  “jockey” shorts or boxer briefs to keep it close to the body.  One of the benefits of an insert, however, is it could be used inside a disposable pant such as GoodNites or Underjams, although that is not recommended.

The foam sensor is rather stiff when first used, which can be uncomfortable for the child to wear at first.  After the first night, however, the foam core conforms to the anatomy of the child and is less rigid and bulky,  and more comfortable.

Inside the box is an alarm module, two sensor pads, instructions, and a wet/dry chart with stars to help keep track of wet nights.  The device itself has two different volumes (Dual Volume Control aka DVC) and comes with a 9-volt battery.

We have found the DVC bed-wetting alarm to be a very good alarm, although somewhat expensive and bulky.  As mentioned, kids may find the sensor pads uncomfortable at first, but they quickly conform to the body and become more flexible.  The alarm is a simple alarm, with 2 volumes, and the loudest setting is definitely one that will get everybody’s attention.

While it is a good bed-wetting alarm, the newer models from different companies are smaller and have more features.
