9.11.2 Wander Control Sequence with Door Control (Open Door)
1 A resident approaches a normally unlocked door that is open. 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
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 The NIRX then transmits a message which includes the identity of the NITX and the identity of
the NILF to the wireless server (NISM2) for processing.
4 If the NITX ID is not authorized to pass through that door the NISM2 sends a message to the
NIRC3 room controller to lock the door.
5 The NIRC3 room controller sends a “lock door” signal to the NICR card reader.
6 The NICR card reader activates the electric door lock and attempts to lock the door.
7 Because the teleCARE IP system detects that the door is open, a wander alarm message will be
initiated to inform the responsible staff member.
8 If Configured, the wander alarm message can also be signalled on linked devices like doorside
modules, corridor lamps and text displays.
