1. SYSTEM INTRODUCTION
1.1. System Components
HALO™ Software: Primary user interface that assists in the assignment and tracking of Transponders,
and displays alarms and other activities in graphical format. It also stores and al-
lows printing of all system events that have been logged.

Controllers:
Controls an egress point and reports any Tag presence at the egress point to the
computer. Depending on system configuration, controllers may control door locks
and local alarms, and allow keypad input for door bypass. They may also provide a
“Nurse Saver” and “Loiter” feature. The “Nurse Saver” feature eliminates nuisance
alarms by not setting off an alarm when the presence of a Tag is detected and the
door is sensed as closed. In the event that the door is open, or is opened when the
Tag is at the egress point, the system will alarm. The “Loiter” feature sounds an
alarm if a Tag detected at a door remains at that door for a period of time, regard-
less of the fact that the door may be sensed as closed.

Controllers will also detect a “Tag off body” condition in its area, as does a Re-

Receivers:
Detects “Tag off body” condition when a Tag is removed from a patient, and reports
this activity to the computer.
this activity to the computer.
Transponders:
Also referred to as “Tags”, these devices are attached to the patient. Tags initiate
two different kinds of alarm conditions as follows:
two different kinds of alarm conditions as follows:
TIC - Tag-initiated-Communications:
This alarm is initiated in the event that a Tag is removed from a patient. This
occurs when the Tag can no longer sense the body of the patient.
occurs when the Tag can no longer sense the body of the patient.
TIF - Tag-in-field Communications:
This alarm is initiated when a Tag enters an area protected by a Controller.
The Controller’s antenna(s) emit a constant field of radio waves that is
picked up by the Tag when in the proximity of the Controller. The Tag re-
ports its presence to the Controller, and therefore the system, when it senses
this field of radio waves.
