Revision 2.0
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 as
the 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.
SYSTEM MAINTENANCE SHOULD INCLUDE THE FOLLOWING STEPS:
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.

5. Installation
5.1.Overview to Installing the HALO System
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.
Figure 6– Typical HALO System Installation
5.2.SYSTEM WIRING
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.

Revision 2.0
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.

5.4.DOOR CONTROL
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.
Figure 11 – Door Coverage
•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:
Øabove the doorway, laid flat on the dropped ceiling tile.
Ødropped inside a wall cavity 4’ above the floor.
Øon 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.

Revision 2.0
Take note of the following:
•Ensure that no tag can reach the protected area without passing through a field.
•The field should not extend into other rooms or areas that are regularly occupied by tags. These tags
could keep a controller in a pre-alarm state preventing the door from opening if magnetic door locks
are being used.
•The tag should be detected at least 4 feet from the door in order to give the magnetic door lock time to
energize.
•Proximity to other fields could also be a factor. If a Tag is able to receive communication from 2
different controllers in the case of field overlap, it will try to respond to both controllers. Each
controller will see Tag communication when it doesn’t expect it and report it as noise, thereby
inhibiting any alarms..
•The antenna should be located be at least 18” away from metal objects, cables, air ducts etc. in order to
be able to create a uniform field with minimal loss of RF power.
Ceiling height, door approach width and metal in the vicinity, need to be considered when planning the location
for the exciter antennae. The field should extend to the floor and cover the entire exit way. A dropped ceiling
consisting of a grid and non-foil backed ceiling tile are the easiest construction materials to work with. Check
above the lay-in tile to see how much space you have and the proximity of metal objects such as pipes, cables
and air plenums. The SRA may also be dropped inside a wall cavity. Sometimes it’s simpler to mount the SRA
on the side of a wall above the door or along the hallway about 5 feet from the floor.
Extensive metal close to the Exciter can distort the field in unpredictable ways. Metallic objects will absorb
and/or reflect radiated energy, which affects the field. This phenomenon can increase or decrease the field
strength in areas causing hot spots or holes in your field. It can even change the shape of the field with tag
detection sometimes occurring as much as 35 ft away. At times this effect can be used to advantage but the
desired result can only be determined experimentally.
Although it is not possible to completely predict the performance of the field for every situation, some
information about the field will help to shorten the process of determining the best location for the SRA. In the
absence of any site irregularities, the field is symmetrical, perpendicular to the antenna length. A cross-section
through the length of the antenna is roughly oval as shown below.
Although the field strength is adjustable, the maximum distance for good coverage is approximately 10 feet.
Sometimes 2 exciters are necessary to get adequate coverage.
5.6.LOCATING THE RECEIVER ANTENNA
The “RX” Antenna should be mounted in a vertical plane. The “RX” Antenna is provided with a removable
right angle fitting that facilitates the desired mounting position. The area to be protected has to be blanketed
by controllers and receivers so that all critical areas have coverage. Elevator Interfaces cannot be included in
the area calculations since the elevator is not always on the floor. Walls, equipment and excess metal could
affect the pickup range. Although greater distances are possible, a maximum of 40’between devices is
recommended.
If it’s not possible to create a proper field with the exciter inside,
an SRA-E exciter antennae could be placed on an outside wall to
limit the penetration of the field into the building. Watch out for foil
backed ceiling tile!
Note: The coax cable used is RG59U with a solid copper center conductor and shield. SEA
exciters draw current therefore do not use ordinary RG59U cables to extend the length supplied as
they used copper clad steel.

Revision 2.0
It is essential that the RX antennas have no metal barriers blocking the signals from the Tags although some
metal objects may enhance communication by reflecting the signal further than it would normally transmit.
Wire glass sometimes found around nurseries can cut down the range. The only way to be sure of adequate
coverage is by testing the results. After all devices are installed and operational, ensure that the entire area has
coverage. Experience will shorten this process as the installer learns what site conditions cause problems.
5.7.FINALIZE CONTROLLER INSTALLATION
Fasten SRA exciter antenna. If installing the SRA above a ceiling tile, use a marker pen to draw an outline of
the SRA in its desired position on the upper side of the tile. Once you are certain of the SRA location, use
some adhesive or caulk to cement the SRA to the tile, preventing it from falling on the floor should the tile be
lifted for any reason.
If the SRA is to be dropped inside a wall cavity, do not let it hang on the coax cable nor hang so low that it
touches the bottom steel plate. Loop the coax cable and wrap a tie-wrap, or band of electrical tape around it as
shown below. Ensure the SRA will hang at the correct height by marking the cable prior to dropping the SRA
inside the wall. Secure the cable when the SRA is hanging in the correct position.
Figure 14 - Securing the Exciter Antenna Cable
Mount the Controller permanently and position the RX antenna. Place the RIM close to the Controller and
connect the three wires on the RS-485 side of the RIM to the RS-485 network. This may be done by using
crimp type connectors, or by means of an EXI TAP box.
The Keypad is designed for flush wall mounting in a standard single-gang electrical box. Should surface
mounting be necessary, an optional SMB box may be used. Should a louder local alarm be desired, either use a
Wire-mold box extension and break out the knock out holes before mounting the panel, or install an external
siren or other audible device.
Install door switch. Hook up Maglock and any peripheral devices. Make sure the Maglock will release in case
of a Fire Alarm. Power up and test the field again.

RIMs have unique serial numbers that are associated with the Controller or
Receiver location that they serve. Ensure that the correct RIM is used at the
location being entered on the floor plan in the computer!

5.7.1.4. THRESHOLD / RX SENSITIVITY SWITCH
The Threshold switch may be adjusted to increase or reduce the sensitivity of the Receiver and therefore
the range of detection of the Tag.
It is also used to remove some of the background noise as well as reduce interference from tags if the
controller is having trouble detecting tags. The result in the adjustment raises the RF field strength
threshold received from the tags in order to trigger the CPM into alarm (ie. from 25uV to 50uV) and
reduces the detection field range.
‘0’ = MAX sensitivity & ‘F’ = MIN sensitivity. The default setting is “2”.
5.7.1.5. TEST CONTROLLER AND SET UP FIELDS
After reading LOCATION FOR SRA EXCITER ANTENNAS, choose a suitable location for the SRA.
Setting up a field is a matter of experience gained by trial and error. The primary considerations here are
the field shape and strength. The field has to fill the area in front of the door all the way to the floor so that
no tag can reach the door without being detected.
To set up a field, start by placing the tag at the range you want for the field at the height a tag is usually
going to be found. The tag needs to be detected far enough from the door to allow the magnetic door lock
time to energize. The tag should be placed on a non-metallic surface for testing. You might want to do a
preliminary field setup by holding the SRA at the approximate location you want to install it but be aware
that your body could be affecting the field. The SRA should be temporarily placed and the field adjusted
for range using this stationary tag. Since the Tag will be read easier in some orientations with respect to the
SRA, it is also necessary to test with the Tag in a variety of positions.
With the SRA and tag in position use the SRA RANGE ADJUST control on the top right corner of the
controller circuit board to set up your field strength. Turn the control shaft clockwise for maximum field
range and counter clockwise for minimum field range.
Holding the tag, slowly pass through all the areas that you need the field to cover. DON’T FORGET
DOWN BY THE FLOOR. The device should continue to beep at a steady rate. An uneven rate indicates
that the controller is not able to read the tag successfully every time.
The final step is to ensure that the field does not extend into other rooms or areas that are regularly
occupied by tags. These tags could inadvertently keep a controller in an alarm state.
5.8.INSTALLING RECEIVERS
Receivers are meant for use where only a “TIC” signal needs to be detected. The “Relay” light on the front of
the receiver comes on to indicate relay activation when a “TIC” is detected. Receivers are not capable of
creating a field of energy using Exciters, as Controllers can, and therefore do not have to be connected to the
Exciter Antennae. Install the RX Antenna onto the Receiver and swivel it so that it is in the vertical plane.
Place the Receiver in the approximate location for final use, connect the power supply and power-up.
