Malem MO3(8) Yellow - Body-Worn Bedwetting Alarm

The Malem MO3(8) Yellow bedwetting alarm is a compact, body-worn enuresis alarm designed to help children learn to wake when they need to wee during the night. The alarm attaches to nightwear close to the shoulder and connects by wire to a moisture-sensitive sensor worn in the underwear.

When the first drops of urine are detected, the alarm sounds immediately to wake your child and prompt them to get up and use the toilet. With regular use, bedwetting alarms help children recognise bladder signals during sleep and gradually develop dry-night habits.

Key Benefits

  • Immediate wetness detection: Alerts your child at the first sign of moisture
  • 8 random alarm tones: Helps reduce the chance of children becoming used to one sound
  • Sound and flashing light: Clear audio alert with visual indicator when activated
  • Compact and lightweight: One of the world’s smallest and lightest bedwetting alarms
  • Supports dry-night learning: Encourages children to respond to their body’s signals

Features

  • Sound-only alarm with flashing light indicator
  • 8 random alarm tones
  • No vibration setting
  • Compact body-worn design
  • Worn on nightwear close to the shoulder
  • Wired sensor attaches to underwear for fast moisture detection
  • Yellow design

This model is designed for families who want a simple sound-only bedwetting alarm. The eight rotating tones may help reduce sound habituation over time.

What’s Included

  • 1 × Malem MO3(8) Yellow alarm unit
  • 1 × Sensor (flat plate or easy-clip depending on option chosen)
  • 1 × Progress chart
  • 1 × Instruction leaflet
  • 1 × Set of three alkaline batteries

How to Use

The alarm unit clips onto your child’s nightwear close to the shoulder. The sensor is attached to underwear in the area where moisture is most likely to be detected first.

Flat plate sensor: Can be placed inside an absorbent disposable pad worn inside underwear or positioned between two pairs of close-fitting underwear.

Easy-clip sensor: Clips securely onto underwear and can be particularly helpful for children who move around during sleep.

Please note: Sensors are replaceable parts and will wear over time due to moisture exposure. Replacement sensors are not covered by the product guarantee.

Awful Product

Broke with a few nights. Got a replacement, it broke too. My child now refuses to wear an alarm and is very upset about the whole thing. This has set us backwards. Cannot recommend at all.

Dear Ian thank you for your feedback - I am sorry you have not had a good experience with the alarm. Did the alarm break or the sensor? the sensors need to be handled with care not to pull it of the garment but to unclip. We are here to support with any issues and resolve them quickly please contact ERIC to resolve this problem. Kind Regards

Good value product

The Malem MO3 is simple to use and effective. It is very sensitive and it will ring the alarm as soon as it gets slightly wet. The clip makes it very easy to apply the sensor

Pleased with the results

We are very pleased with the result as the product has worked and our son is dry. It didn't work as quickly for us as some others have said but we stuck with it and that was the best thing to do. We found that the alarm and flashing light did not wake our son up (he is a very deep sleeper!) but it woke us up from our room and we would go in. He was happy to try it and has been willing to wear it ever since. We are nearly at the six week mark and it has been great to capture the progress he has made on the chart which we stuck on his bed. All in all, a good product and seems to have done the trick!

Excellent product

Can’t believe we didn’t try this sooner! If your child is struggling with bed wetting and is motivated to use an alarm this really is excellent! Only took a couple of nights for her to get the hang of it. Continued to use it for few weeks just to reinforce the brain/bladder learning but it’s been a revelation!

We’ve had great results

I not one for writing reviews but as a parent who had been putting this off (after being recommended it by the dc) we’ve had great results. My 9 year old daughter would regularly be so wet in the night that she would split the sleep nappy she wore, I had little hope we could reverse this volume as it seemed out of her control. She was petty scared of the thought of the alarm going off but I tried to reassure her and moved into her bedroom for a week and we had pretty good success straight away and we stopped using after a week as she would see herself up and ask to help going to the loo. A few months later things aren’t prefect with the odd accident but it’s been life changing results for us.
