Malem Bedwetting Alarms


MALEM Bedwetting Alarms, designed  in 1980, revolutionised the treatment of bedwetting by developing the first ever body worn bedwetting alarm. MALEM has been the leading bedwetting alarm worldwide for the last 35 years. 

As a sign of their success and reliability in treating bedwetting, MALEM Bedwetting Alarms have been awarded the contract to supply the NHS for over 25 years,  and are the still the most popular, reliable, and successful bedwetting alarms available.

The MALEM Bedwetting Alarm range is extensive, and designed with your child in mind.  The range includes wearable alarms, wireless alarms, and bedside alarms.  The alarms come equipped with a range of features for waking your child, including sound, with up to 8 different options; vibrations; or even a personalised recorded message, which can be useful and particularly calming for children with special needs.

MALEM Bedwetting Alarms are well constructed, compact and durable. They come in a range of cool colours, that your child will love.  The alarm sounds are effective, and have been specifically chosen to ensure your child wakes up.

All MALEM bedwetting alarms come ready to use straight out of the box.  You get everything you need to get started, including the sensor, and the batteries.  There are clear instructions on how to use the alarm, and a chart to mark your child’s progress.

All MALEM bedwetting alarms work in the same time-tested manner; they train your child to exert automatic control over their bladder, and stop bedwetting!  To choose the alarm best suited to your child’s needs, see our comparison table here.

There are 3 main types of alarm:





Malem Wearable alarms consist of two parts; the highly sensitive Moisture Sensor, and the Alarm. The Alarm is clipped onto the pyjama top near the shoulder. The easy clip moisture Sensor is clipped to the outside of the underwear ( or in the case of the standard sensor,  positioned in between 2 pairs of underpants or inside a sanitary pad). When a child wets the bed, the Moisture Sensor detects the urine immediately, and activates the Alarm. The Alarm will give out a loud sound, and a light will start to flash. The Ultimate Alarm comes with an additional vibrate feature, which is designed to wake even the deepest sleeper, by providing multiple sensory stimuli. The Alarm will continue to sound until the Moisture Sensor is removed from the underwear and the reset button is pressed.

The wearable alarm range consists of:

MO3 Audio alarm: Sound + flashing light

MO4 Ultimate alarm: Sound + flashing light + vibration

MO4S Ultimate Selectable alarm: Multiple sound settings + flashing light + vibration

MO5 Ultimate 1+ Record alarm: Sound (personal recorded message or pre-set sounds) + flashing light + vibration

The MO3 Audio alarm is the smallest and lightest of the wearable alarms. They are well constructed, compact, very effective and come in funky cool colours that kids love.
The alarm is available as single tone alarms (red, green, and orange) or as an 8 tone alarms (yellow and camouflage). The single tone alarms make the same sound each time the alarm is triggered. Some parents notice that their child is getting used to the same tone, and starts to tune the alarm out (called “auditory accommodation”). In these children, the 8 tone alarm can be used. When using the 8 tone alarm, each time a child wets the bed a different tone will automatically sound. Malem Enuresis Alarms have loud sounds specifically selected for their effectiveness at waking children. The alarm will sound continuously until the sensor is removed from the underwear and the reset button is pressed.

The MO4 Ultimate alarm combines the audio alarm and flashing light with vibration. This system has been designed to wake even the deepest sleeper by providing multiple sensory stimuli. A selectable combination of sound and vibration suits the needs of the child. A selection switch can be easily set to sound only, sound and vibration, or vibration only. This gives the user greater freedom and flexibility and allows adjustments for different settings and situations. The silent vibration mode means that the alarm can be used in shared settings, such as in dormitories, whilst the audio settings can be used at home. The alarm’s audio alarm can be single tone or 8-tone. The single tone audio (+ light + vibration) alarm is available in blue, pink and purple. The 8-tone audio (+ light + vibration) alarm is available in gold.

The MO4S Ultimate Selectable alarm is a very versatile alarm. As well as sound and vibration settings (as for the MO4 Ultimate alarm), users can select any one of 8 individual alarm sounds to consistently sound on activation. Alternatively, the 8-tone setting can be selected, which randomly plays one of the 8 alarm tones on each successive activation. .These alarms are available in magenta, royal blue and camouflage.

The MO5 Ultimate Recordable alarm is the world’s first bedwetting alarm that allows you to recinord your own sounds or audio message. Once recorded, your own personal message or sound can be selected to sound on detection of moisture. Within the same alarm, pre-programmed audio sounds are also available and can be selected stead of the recorded personal message/sound. The alarm also has a vibration setting which can be used in addition to or instead of the audio options.  This alarm is available in red and royal blue.

Wireless Alarms

The Malem MO12 Wireless alarm is ideal for children who prefer not to wear pyjamas to bed.  This alarm consists of a sensor/transmitter and a receiver that communicate wirelessly with each other. The magnetic transmitter clips to the underpants’ waistline and the attached sensor is clipped to the outside of the underpants, where urine is likely to be expelled. The receiver is placed in the same room, in a position where the child has to get up out of bed to press the alarm’s reset button. Additional receivers can also be purchased and placed in the parents’ room.

Once moisture is sensed, a loud sound comes from the receiver. Once this receiver is triggered by wetness, it continues to sound until the reset button is pushed. This helps insure that you and your child wake up to the alarm, and your child gets out of bed to turn it off. A volume control dial on the receiver allows the user to control the level of sound. This alarm also offers the choice of 8 random sounds or selecting one of 8 sounds to play each night.

Bedside Alarms

The Malem MO6 Ultimate Bed-Side alarm is ideal for children who do not want anything attached to them whilst they sleep. The Malem Bed-Side alarm is the loudest bedwetting alarm in the Malem range.

The Malem Bed-Side alarm consists of a Bed-Mat sensor, which is placed beneath a towel or cotton sheet for comfort under the child whilst they sleep. This Bed-Mat works as the moisture sensor and is connected to the Bed-Side alarm via a cord. On urination, the Bed-Mat detects the moisture and activates the Malem Bed-Side alarm unit, resulting in a loud audio alarm. The alarm can be selected to be either a single sound or an 8-tone setting, reducing auditory accommodation, or you can record a sound or voice to be played when the alarm is activated.

Once the alarm is activated, the child must get out of bed to press the reset button.
