SensAlert 300 has been developed as a LOW INTRUSION care solution to assist carers monitor individuals at risk of falling by generating an alert when the person is most at risk.
Versatility is offered with several modes of operation…

1. IMMEDIATE ALARM for when a person at high risk attempts to leave bed or chair

2. DELAYED ALARM for when a person at low or medium risk leaves their bed or chair, and does not return to within a pre-determined time (e.g. 10 minutes)

The alert can be set to LOW, MEDIUM or HIGH Volume, in the form of a TONE, VOICE Recording, or SILENT when using in conjunction with a Nursecall system.

There are also innovative X-10 options available which can automatically switch on lights (e.g. bedside lamp and bathroom light) when the person gets out of bed, and automatically switch the lights off again when the person returns to bed, again reducing the risk of falling in the dark.

Every year, between 33% and 50% of people over the age of 65 suffer a fall.

For every 100 of those people who fall, 20 will need medical help and around 10 will sustain a fracture.

  • Select Bed or Chair sensor mat and connect to “SENSOR” socket on control unit.
  • Locate the Bed Sensor Pad under the mattress as instructed (see sensor pad instructions) or Chair Sensor Pad on the chair (ideally in or under a cushion)

How to use

  • Place the pad on the chair or bed (note if you have an under or over mattress sensor pad) so that the bulk of the patient’s weight (buttocks area) is resting on it.
  • Ensure the sensor pad is plugged into the “SENSOR” socket
  • When the patient’s weight is placed on the pad, you will hear the confirmation tone beep twice, which indicates that the system is operational and active.
  • When the patient moves from the pad, the selected alarm tone or voice message sounds to remind the patient to sit or lie back down and alerts staff that a patient is at risk of falling.
  • The alarm automatically resets when the patient returns to the pad, or the control unit is reset using the “RESET/TEST” button.
  • The “IN USE” light will blink every 3 seconds to indicate the system is operational.

Testing the System

  • Test the system before each use and inspect the pads and control unit regularly to ensure they are not damaged.
  • Test the system by pressing firmly on the pad. When you remove pressure, the alarm should sound. Reset the alarm by pressing the “RESET/TEST” Button.
