Examples of alarms and sensors:

Audible alarm – The most
basic form of alarm is an audible alarm from the device itself. This means that someone
in another room of the house can be alerted.
Direct alert to
carer – The device can be linked to a receiving device. This means that
the carer can also wear a linked device so that wherever they are they can
be alerted.
Monitored device – This is a
service which means that once the alert button is pressed a central team is
notified that a problem exists. They can then ensure that the appropriate action is
taken which could be contacting the carer, visiting the patient or alerting
the emergency services.
Bed/Chair Sensors are pads which you place either on a chair or under the sheet of a bed. When they sense that the person is attempting to stand the carer is alerted by an audible alarm. Alternatively, if you want to be alerted specifically when a person has left their bed you can place pressure pads by the side if their bed. When someone leaves their bed, and stands on the pressure pad the carer can be alerted.
Property Exit Sensors can be used when somebody is
unable to leave the house unattended or if they have left the house at an inappropriate
time. They work in a similar way to personal alarms in that they will notify
the carer when the alarm is triggered. They work by installing a
sensor in the door which can monitor when the door is opened and closed.
Fall Sensors are worn around the neck, on the wrist or carried in a
pouch. It can detect when the wearer has fallen, by sensing sudden
jolts or senses that the wearer is not standing vertically. Once a fall
has been detected it produces an alert in the same way as a personal alarm
to ensure that the appropriate care is provided as quickly as possible.
