9.11.3 Wander Control Sequence with Buddying
The wireless module of a resident can be configured to allow “All staff members” or just
one single staff member to act as buddy.
1 A resident approaches a normally unlocked door which has an “active” NILF beacon. 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 active NILF’s ID signal it transmits an RF signal which contains the
resident’s NITX ID and the ID of the active NILF. This message is received by the NIRX that is
mounted on the NIRC3 room controller.
3 A caregiver accompanies the resident in the area of the normally unlocked the door with the
“active” NILF beacon. The LF signal containing the NILF ID is received by the caregiver’s NITX
mobile transceiver.
4 When the NITX receives the active NILF’s ID signal it transmits an RF signal which contains the
caregiver’s NITX ID and the ID of the active NILF. This message is received by the NIRX that is
mounted on the NIRC3 room controller.
5 The NIRX then transmits a message which includes the identity of both NITXs and the identity
of the NILF to the wireless server (NISM2) for processing. If the residents NITX ID and the
caregiver’s NITX ID is recognized as a “Buddying” combination then the NISM2 does not send a
message to the NIRC3 room controller to lock the door. The NIRC3 room controller does not
send an “unlock door” signal to the NICR card reader. The door remains unlocked and the
resident accompanied by the caregiver can pass through the door.
Note: If the resident is not accompanied by a caregiver, or the resident and caregiver are not
recognized as a “Buddying” combination (in a single buddy configuration only), then the
NISM2 will send a message to the NIRC3 room controller to lock the door (as shown in
example 9.11.1 on page 88).
