Bed Occupancy Sensor The bed/chair absence sensor generates an alarm if
a client has got out of bed (or chair) during a
monitoring time window (e.g.
night)
The bed/chair absence sensor works like the
conventional bed/chair occupancy sensor,
generating an alarm if a client has got out of bed (or
chair) during a monitoring time window (e.g.
night) for longer than a considered safe period of
time (configurable). When the client gets out of the
bed/chair (during the monitoring period), the timer
is started. If the timer expires before the client has
got back into the bed/chair then a Bed/Chair
Absence event is generated. However, the sensor
also provides the ability to extend the time period if
user activity is detected elsewhere in the property
e.g. client has gone downstairs to make a drink,
therefore reducing false calls. The home unit
supports two Bed/Chair Absence sensors. It is also
possible to set an alarm to be raised if the user does
not go to bed or fails to get up out of bed at a
configurable time.
