Malem Wireless Bedwetting Alarm

The Malem Wireless Bedwetting Alarm is easy to set up and use while remaining comfortable, compact and lightweight. Its design allows for it to be used on any pair of underpants as it clips magnetically to the underpants waistband and uses Malem's famous unisex Easy-Clip© sensor.

How it works

Malem Wireless Bedwetting Alarm Diagram

Attach the small transmitter to the outside of the underpants waistband using the magnetic clip.

Attach the Easy-Clip to the outside of the underpants. When urination commences and the sensor is moistened the alarm is triggered.

Repetitive awakening by the alarm as soon as urination commences will gradually train the brain to exert automatic control over the bladder.

Eventually, the bed wetter will either wake up before urination or sleep throughout the night without needing to empty the bladder. This form of treatment has proved to be the safest, most reliable and economical way of solving bedwetting with over 90% success within a few weeks and has no side effects.

The 8 sounds are designed to prevent 'auditory accommodation.' They are eight distinctly different loud sounds only one of which is activated each time the alarm is triggered.


  • Single tone or 8-tone audio setting
  • 8 random sounds to prevent 'Auditory Accommodation'
  • Flashing LED
  • Volume control
  • Battery operated (no mains electricity)
  • Long range 25 metres
  • Small sensor/transmitter magnetically attaches to underwear and sends signal to separate receiver
  • Ideal for children who do not wish to wear pyjamas in bed
  • Can be used for geriatric incontinence management (additional receivers can be purchased for parents/carers)
  • For the treatment and cure of Enuresis (bedwetting), the receiver must be in the same room as the transmitter

Additional Receiver package available for parents to have one receiver with the child and one in the parents room. This makes it easier to be awake and support your child during the training process.

Great product
The alarm was quick and easy to set up and has been very effective. We are in our 3rd week and have seen excellent results so far. Compact design and child was able to manage use independently after a few days. (Posted on )

Progress being made
We have been using the alarm for about 3 weeks and are making steady progress.
Miss 7 previously had only a handful of dry nights. She is now averaging 2 per week and is starting to wake to the sound of the alarm. I am still sleeping on the trundle in her room to make sure she wakes and help with the wet sheet protector if necessary. I must say I under estimated the parental involvement as I didn’t realise I’d need to be so involved. But I hope it won’t be too long before she always wakes without assistance if the alarm goes off. She started off fully wetting and sleeping through the alarm. We are now only damp and starting to wake. There is a family history of bed wetting and older family members wish this technology was available to them as children. (Posted on )
