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.
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 crib during this test.
- Check that the Sensor Pad is in the middle of the cot underneath the mattress - this is regardless of where baby is in the cot
- Switch the Camera Unit & Parent Unit ON
- Press the MENU button to access main MENU
- Press the down arrow to the Sensor Pad icon and press OK to enter
- Press the down arrow and press OK
- Press the UP or DOWN arrow until sensitivity is at 2 - this is the factory setting and should only be adjusted if required
- Press OK
- Press the DOWN arrow to the Save Icon on the bottom of the screen and press OK to save this setting
Please Note if you do not carry out this last step the monitor will revert to the setting it was previously on and you will need to begin again.
*Gently place your hand in the furthest corner of the mattress & and wait for 20 seconds. If the movement alarm (series of loud continuous beeps from the parent & camera unit) does not sound please carry this out on the remaining corners.
- Remove your hand from the mattress and step away from the crib. The Sensor Pad is sensitive enough to detect your movement if you are touching the cot.
**Due to the lack of movement, after 20 seconds the movement alarm (series of loud continuous beeps from the parent & camera unit) will sound from the Parent & Camera Unit.
- Step back to the cot and 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 alarm sounds when you place your hand in any of the corners please adjust the sensitivity by turning it up 1 level 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.
Also, have you tried replacing the CR3032 Lithium battery in the Sensor Pad - it is recommended that this is replaced a minimum of every 4-6 months to prevent false alarms.
This battery is available from online stores.
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
