9.13 Typical example of teleCARE Wireless with Exit Detection
9.13.1 Unsupervised Exit Detection
1 A resident approaches a door that has an exit beacon (Active NILF). The NILF periodically
transmits an LF signal containing the NILF ID which is received by the resident’s NITX mobile
transceiver.
2 When the NITX receives the exit beacons ID signal it transmits an RF signal which contains the
NITX ID and the ID of the exit beacon. This message is received by the NIRX that is mounted on
the NIRC3 room controller.
3 The NIRX then transmits a message which includes the identity of the NITX and the identity of
the exit beacon to the wireless server (NISM2) for processing.
4 If the NITX ID is authorized to pass through that door the NISM2 changes the presence state of
the NITX to “Absent”. “Device lost” messages and the “Check-in” functionality will be
suppressed when the NITX is absent.
Note: If a resident is not authorized to pass through the door, the exit beacon can also
function as loiter and/or wander alarm beacon supporting access control, which means the
door will be locked and a loiter and/or wander alarm will be generated.
See “Typical Examples
of teleCARE Wireless with Wander Alarm” on page 88.
and “Typical Examples of teleCARE Wireless
with Loiter Alarm” on page 92
.
Note: An exit beacon cannot be used to return the state back to “Present” when a resident
arrives back at the site. For returning to the “Present” state, an active location beacon that
is not configured as exit beacon is required.
See “Returning at the Site” on page 95.
