SYSTEM MAINTENANCE SHOULD INCLUDE THE FOLLOWING STEPS:
4. INTRODUCTION
This manual serves as a guide for Installers of the HALO system. The major components of the system are
described, as well as the system’s intended functionality, so as to gain familiarity with its operation prior to
installation. In order to successfully install and commission the system, it is absolutely critical to
understand the capabilities of the system and its components prior to installation.
4.1. About Halo Infant Protection System
Halo is a premium infant protection system. Halo works in conjunction with the EXI P-tag patient
transponder that is capable of sensing if it has been removed from the infant. Halo is an electronic system,
which, in conjunction with staff diligence, creates a secure perimeter to deter infant abductions.
The function of the HALO system is to monitor areas within a building for the presence of HALO Tags. A
Tag is sensed when it either enters an RF Field that is set up using the EXI HALO Controller (referred to as
a Tag in Field or TIF), or when the Tag initiates an alarm signal (referred to as Tag Initiated
Communications, or TIC).
HALO is designed to assist staff in providing a higher degree of safety for patients. It is not intended asthe sole means of protection in preventing a wanderer or infant from leaving the premises. Regular
checks to verify that your HALO system is operational is highly recommended.
All Tags should be checked for physical damage after each cleaning, disinfecting or sterilization
procedure.
Each Tag should be tested for correct operation before being attached to an infant. The HALO
software prompts for testing of Tags prior to their deployment. Please refer to the appropriate
section in this manual for the instructions.
The warranty on Tags is 3 years, and the batteries within the Tags are expected to last in excess of
the warranty period depending on the usage pattern. Do not leave Tags in the detection field for
long periods of time, and store them in the foil bags supplied. Failure to do so will result in false
alarms, and will reduce battery life.
Set up a regular system check schedule to verify that the Controllers, Receivers and Tags are
operational. Controllers should have the “Ready” light illuminated to show that they are powered.
Check the operation of the Controller daily by starting a bypass or triggering an alarm using a Tag
to ensure that it is fully operational and protecting the egress point where it is located.
Check each Receiver on a regular basis to ensure that it can receive signals from Tags in the “Off
Body” condition. Failure to regularly check for this operation may lead to failure to detect a Tag
that is removed from an infant, and therefore compromising protection for the infant.
Whenever you see an infant who is a patient, look for the Tag on this infant to verify that it is still
securely attached. This may require special knowledge as to the placement of the Tag.
Conduct frequent back-ups of Activity Logs for future reference.
Individual power supply adapters Model # AR2PS01-024 may be used for each of the Door Control
Packages and the Receivers. Alternatively, a Central Power Supply Model # AGECP01-624 has 6
independent inputs, each of which can power one Controller or two Receivers. The CPS may be purchased
with a battery back-up option, which is highly recommended.
EXI HALO is designed to provide extended periods of reliable service. Once installed correctly, the system
does not require tuning or adjustments, and it should provide exemplary service unless the position of its
components is subsequently disturbed, the physical environment is altered as in a renovation, or a very strong
noise source is introduced into the environment.

The HALO network is based on the RS-485 electrical interface standard, which is 2-wire multi-node bus.
The EXI HALO elements are designed such that many more than the RS-485 limit of 32 Drivers and 32
Receivers can be co-exist on the same network. The baud rate used in the HALO system is 57,600 bps, and
therefore in order to avoid data corruption it is important to ensure that a clean signal is always present.
Using the right type of cable, network topology, and not exceeding total cable length are critical factors in
ensuring that the system will operate reliably.
Cable capacitance is a large factor in determining the quality of the signal on the network, and EXI recommends that
cables with capacitance of greater than 15 pf per foot should be avoided. The network should be constructed using a
“multi-drop bus” type topology, avoiding any “star” type configuration. The system is designed to operate with up to
4,000 ft of cable with the recommended topology and cable. The total cable length varies depending upon the cable
capacitance and nominal impedance, topology, and number of devices on the network. If the estimated total cable
length is greater than 4,000 ft, a RS-485 Repeater will be required to ensure that the system works reliably, or works
at all. It is also recommended that a Repeater be used to isolate HALO Elevator Controllers from the main system to
minimize noise pick-up and loading of the system. Cables used in Elevator shafts should be stranded and not solid,
and should be resilient enough to withstand the continuous flexing that it will experience for many years in the
elevator shaft.
The figure below shows the details of connecting the various system components together for the HALO
system.

Daisy Chain (Series) Configuration as much as
possible.
The controller chassis may be horizontally or vertically mounted, on a wall, ceiling or shelf and should be
mounted so that the front face panel is easily accessible. Since it is preferable to leave the RX antenna attached
directly to the controller, the exact location of the controller will affect the reception of the tags and should
only be finalized after setting up the field. The RX antenna should be positioned on a vertical plane for
maximum performance.
• Mount the Keypad about 10’ away from door so that it can be used before entering the detection
field.
• Maglock release should be hooked up to an unused auxiliary normally open contact from Fire
Alarm Panel.
5.5. LOCATION FOR SRA EXCITER ANTENNAS
One of the most important aspect of the entire installation is the correct positioning of the SRA Exciter
Antenna. The Antenna may be installed:
Ø above the doorway, laid flat on the dropped ceiling tile.
Ø dropped inside a wall cavity 4’ above the floor.
Ø on the side wall along the hallway 4’ above the floor.
Each field needs to be fully tested to ensure adequate coverage of the protected area.
