Firstly, we want to reassure you that if you are hearing the Alarm from your monitor it indicates that your monitor is working as it should - the Nursery Unit is not receiving any signals from the Sensor Pad to indicate movement is detected so the monitor is alarming. The monitor is set to alert you once it does not detect your baby's movement on the surface of their mattress for 20 seconds.
Angelcare Monitors monitor your baby’s movements on the surface of their mattress - whether this is the rise and fall of the chest or other subtle movements.
Young babies do have different sleeping/movement patterns compared to toddlers when sleeping and this is perfectly normal.
As baby grows, becomes more mobile in the crib coupled with extra layers, a wet nappy, lying on their sides, hunches and in a favourite corner of the crib - these can make it harder for the movement sensor pad to detect baby's movements.
In such instances, the sensitivity may need adjusting to allow for this. The Sensor Pad can detect movements over the whole of the surface of your baby’s mattress, from corner to corner if it is at the correct level. Additionally, it may be that the sensitivity has accidentally been changed in the settings. It's not a regular occurrence but it can happen.
Sensor Pad False alarms may happen for several reasons:
- Nursery Unit has not been turned OFF after you have removed your baby from the crib
- Make sure there is no bedding between the mattress and the Sensor Pad
- Sensor Pad has not been placed under the mattress properly. If your cot does not have a solid, stationary, completely flat, firm surface including a spring or slat base, place a hardboard between the crib base and the Sensor Pad, to ensure correct operation. The hardboard support must measure at least 30 x 30 cm (12” x 12”) and 6 mm (1/4”) thick
- The sensitivity level may also need to be adjusted
Therefore, to establish whether your Sensor Pad is at the correct level for your baby's mattress carry out the “Four Corner Test”, see below for information on how to do this.
AC1100 - Four Corner Test
NOTE: Please follow step 2 within 20 seconds after turning ON both units otherwise the movement alarm will sound.
Your baby must NOT be in the cot during this test.
- Firstly, check the level that the sensitivity is set to, this is done by following these steps:
- Switch the Nursery Unit & Parent Unit ON
- Pressing the MENU icon, bottom right on screen
- Press the SUB MENU (SETTINGS) icon, bottom right of the screen
- Press the Sensor Pad sensitivity icon until there are 3 green bars highlighted just above the icon - this is the factory setting
- Press OK
- Press OK again
- Switch the Nursery Unit and Parent Unit OFF
- Check that the Sensor Pad is in the middle of the cot underneath the mattress.
- Ensure that the Sensor Pad cord is fed through the base of the cot using the cord cover kit to secure the cord
- All cords must be kept out of reach of your baby at all times
- The Nursery Unit must be at least 3ft away from the cot
- Switch the Nursery Unit & Parent Unit ON
Gently place your hand in the furthest corner of the mattress & and wait for 20 seconds
*If the pendulum symbol on the Parent Unit screen swings and the green light flashes on the Nursery Unit registering your hand then the sensitivity is correct and repeat in the remaining 3 corners
Remove your hand from the mattress and step away from the cot. The Sensor Pad is sensitive enough to detect your movement if you are touching the cot
**Due to the lack of movement, after 15 seconds a single beep (The Rouse Alarm) will be emitted from the Nursery Unit
After a further 5 seconds a series of continuous beeps (The Main Alarm) will sound from the Nursery Unit & Parent Unit
Place your hand on the mattress and after a few seconds the alarm will cease as the Sensor Pad will have detected your movement.
*If the pendulum does not swing when you touch any of the corners please adjust the sensitivity by turning it up another bar and repeat the Four Corner Test again.
**If however the monitor does not alarm when you step away from the cot reduce the sensitivity down 1 level and repeat the Four Corner Test, keep adjusting this until the alarm sounds ensuring that the movements is still detected in all four corners.
Try this new setting over the next couple of nights and monitor the amount of false alarms you have, re-adjust if necessary by turning the Sensitivity Dial up another bar.
If the Four Corner Test does not resolve your query
• Is your baby asleep when you go in to check
If yes, this would indicate that your baby is in a deep sleep as the alarm has not woken baby
• When you check on your baby does the alarm continue or does it cease on its own
If the alarm ceases on its own this will be because the alarm has re-established your baby’s sleeping pattern
If the alarm does not cease on its own please let us know
• Does the alarm only happen at night
If yes this is because you baby, as with adults can go into a deeper sleep at night rather that when they nap during the day
• Is there a particular time that this is happening
Baby’s have sleeping patterns when they go in to deep sleeps and because of this the alarm can go off at certain times in the night
• Are you using additional sleep aids such a Sleepyhead, Cocoonababy etc
We do not recommend the use of the Sleepyhead with the Angelcare Movement Monitor, as this could mask the movement of baby. We have had parents contact us with this issue when using the combined products
• What type of mattress are you using
We know that the Sensor Pad will work effectively with a standard hypoallergenic, spring, coir (and spring/coir combined) mattress as these allow your baby’s movements to be transferred down on to the pad.
We also know that the Sensor Pad will NOT work with a Hollow Framed, Dual Sided, Memory Foam Mattress;
A Hollow Framed Mattress is mainly a US product, it is basically a number of poles that are fitted together with a tight cover fitted over this. As a result of their being nothing actually inside the mattress (hollow) no movement is transferred down to the Sensor Pad. As a result the monitor may false alarm indicating that baby`s movements are not being detected by the Sensor Pad.
A full Memory Foam or Dual sided Memory Foam Mattress masks the movement of your baby on the surface of the mattress due to the density of the foam and baby`s movements do not transfer down to the Sensor Pad. As a result the monitor may false alarm indicating that baby`s movement is not being detected by the Sensor Pad
