Alerta Wireless Window and Door Sensor, Exit Monitoring for Safer Dementia and Risk Management Care
- Magnetic contact sensor detecting door or window opening and transmitting an immediate wireless alert, providing the earliest possible notification that a patient with dementia or cognitive impairment is attempting to leave a safe zone before they have travelled more than a step beyond the exit point, giving carers maximum response time for gentle redirection.
- Non-restrictive exit monitoring supports the Mental Capacity Act 2005 least-restrictive principle, alerting staff to exit attempts without physically locking doors or windows, maintaining the patient's freedom of movement while ensuring carers receive the earliest possible notification to provide supervision before the patient reaches an unsafe external environment.
- Easy surface-mount installation with no wiring across windows or doors, with the compact sensor unit and magnet mounted on the door or window and frame respectively, providing immediate exit monitoring in care home rooms, communal areas and garden exits without structural modification or professional installation.
- Battery powered (2x 1.5V AAA batteries) with 95m wireless range to the Alerta Wall Point Receiver (sold separately), enabling deployment at any door or window within the care environment without proximity to a mains power point, with exclusive 433MHz pairing preventing cross-interference between systems in adjacent rooms.
Alerta Wireless Window and Door Sensor: Contact Sensor for Dementia Exit Monitoring Without Restraint
The Alerta Wireless Window and Door Sensor is a magnetic contact sensor mounted across a door or window and its frame, transmitting an immediate wireless alert via the Alerta Wall Point Receiver when the monitored exit point is opened. Designed for use in dementia and cognitive impairment care settings where unsupervised exit creates a safety risk, the sensor provides the earliest possible notification, at the moment of door or window opening, giving carers maximum response time to intercept the patient before they reach an unsafe external area. Battery-powered and easy to install without wiring, it deploys across any door or window within 95 metres of the paired Wall Point Receiver.

Clinical and Regulatory Compliance
CQC Regulation 10 (Dignity and Respect) and the Mental Capacity Act 2005 require that any restriction on a person's freedom of movement is proportionate to the risk it addresses and is the least restrictive option available. Locking doors to prevent dementia patients from leaving a safe area is a Deprivation of Liberty Safeguard restriction requiring authorisation. The Alerta Wireless Door Sensor provides a less restrictive alternative: doors remain unlockable while the sensor provides the carer notification that enables responsive supervision. NICE Guideline NG97 (Dementia: Assessment, Management and Support) recommends that care environments support people with dementia to move safely rather than imposing physical restrictions, and the door sensor supports this by enabling responsive supervision rather than physical barrier.
Frequently Asked Questions
Does the Alerta Door Sensor work on fire doors, and are there fire safety considerations?
The Alerta Door Sensor can be mounted on fire doors as a surface-mounted sensor that does not interfere with the door's fire resistance or self-closing mechanism. However, the monitoring system must not be used to lock fire exits or restrict their emergency opening. Any modifications to fire door function must be assessed by the fire safety responsible person in accordance with the Regulatory Reform (Fire Safety) Order 2005 independently of the Alerta sensor installation. Confirm with the care home's fire safety responsible person that the specific door's fire safety function is unaffected by the surface-mounted sensor before deployment.
Can the sensor be reset to stop alerting after a monitored exit has been responded to?
The alert transmits to the Wall Point Receiver when the door is opened. Once the door is closed, the magnetic contact is re-established and the sensor resets. Subsequent openings generate a fresh alert. The Wall Point Receiver alert sound continues until manually silenced or until it times out according to the receiver's settings, after which the receiver returns to standby ready for the next alert. Responding carers should silence the Wall Point Receiver upon attending to the alert, in accordance with the care home's monitoring response protocol, to prevent the alert sound continuing after the exit attempt has been managed and documented.
