System Description
teleCARE IP
Dynamic Mode
In “Dynamic Location” mode, the NITX can move around the coverage area and speech will
be automatically directed to the current location of the NITX when a call is received.
The real-time location of the NITX is determined by LF beacons (NILF) mounted at the
entrance to each room. The NILF transmits an LF location signal which is received by the NITX. The
NITX memorizes its’ current location until it receives a new LF location signal. The memorized (last
known) location information is included in all transmissions from the NITX. The phone number to be
called is automatically updated to the current location of the NITX when a call is received
and the speech response will be directed to the telephone number of the NISP at the location of the
call.
Dynamic Location Mode Example
Figure 74. Wireless call example with speech - dynamic mode
The example consists of three room controllers (NIRC3) and five corridor lamps, Each NIRC3
has a transceiver module (NIRX) and a voice piggyback module (NIVP). In each room there is
a doorside module (NIDM) combined with a speech module (NISP). At the door to each
room an LF location beacon (NILF) is mounted. The LF location coverage (green area)
includes the door to the room. The two main entrance doors have a location beacon (NILF)
and a card reader module (NICR) for access control (yellow area).
9.8.2 NILF Beacon Modes
The LF beacon (NILF) can be configured as a “Passive” beacon or an “Active” beacon using
DIP switches situated in the NILF housing (described in the teleCARE IP Installation Guide
TD93021US).
Passive Location Beacon
When passive mode NILF beacons are used the NISP telephone number will not be updated
if the NITX subsequently moves between passive locations after a call is received. The
speech location will remain at the location where the call was first received.
