1. INTRODUCTION
1.1. Intended Audience
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.
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 Initi-
ated Communications, or TIC).
1.2. SYSTEM OPERATION
The EXI HALO system uses Radio Frequency waves for communications between the HALO system
components and the Tags. The HALO Controller continuously emits a 307 kHz RF frequency via the
Exciter Antenna, setting up a field in its local area. When a Tag enters this field, a Radio Receiver
within the Tag senses the 307 kHz RF field and transmits its identification information to the HALO
Controller using a low level Radio Signal at frequency of 434 MHz.

2. DECISIONS TO MAKE PRIOR TO INSTALLATION
2.1. 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.
Figure 2 - "Bus" Topology Figure 3 - "Star Topology
Cable capacitance is a large factor in determining the quality of the signal on the network, and EXI rec-
ommends 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 ca-
ble. The total cable length varies depending upon the cable capacitance and effective resistance, topol-
ogy, 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.

2.2. CONTROLLER CONFIGURATIONS
The HALO controller handles all communication with the Tags, provides audible and visual indicators
of what state its in and prevents egress when necessary. 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. This device is fully capable of operating in stand-alone mode although it does pro-
vide for communication to several different types of central reporting systems. The front panel provides
easy access to a number of different output formats as well as allowing inputs to alter some of its
automatic functions as necessary. Local alarm and bypass annunciation is available through several dif-
ferent user interface devices. These devices are discussed in more detail in Section 2.4 KEYPAD OR
PINPAD?
The Tag serial numbers as well as status information is output in Weigand format on 2 of the output
pins. This is a standard format used by many Card Access Systems. The MagOut line will engage a
Magnetic Door Lock when Tag’s are detected in the field. Due to NFPA 101 regulations being
adopted in many locations, it may be mandatory to provide an automatic door release with 15 seconds
after a door has been locked up. The controller provides 2 Form-C dry contacts rated at 2 Amps @
30VDC. They switch ON to indicate the 2 different alarm conditions – Tag In Field (TIF) and Tag
Initiated Communication (TIC). These Relays can be used to turn on remote signaling devices such as:
- Nurse Call system annunciators (should have latching function)
- EXI model “SSM” 2-zone audible alarm with selectable tone sequences
- EXI model “ANN-6L” Audible-Visual 6-zone, LED type non-supervised
Annunciator
- EXI model “APEX”, supervised Annunciator system through inputs of
an APEX I/O-8
Contact EXI for more information on each of the above systems and wiring diagrams for many differ-
ent situations.
The Door Switch is used by the HALO controller to disable alarm reporting when the door is closed.
This is known as the Nurse Saver Feature. Although Tags are still detected and reported to a central
system, no alarms are annunciated until the door opens. At that time, all the Tags are re-read by the
controller so that only the Tags that are still in the field will cause an alarm. The door switch is also
useful during bypass as the controller will detect the door opening and then terminate the bypass as
soon as the door closes.
A remote system or switches can use three input lines to alter the normal operation of the controller.
Unlock In provides a temporary release of the door. Alarm in will cause an immediate lockup of the
door with the local and remote alarm annunciators on. Override In will disable the controller so that
no tags are read and nothing will be reported to the Host computer. Shorting the appropriate line to
ground will activate the function.
Please refer to the HALO Controller Operation Manual for a more detailed description of the con-
troller functions.
2.3. LOCATION FOR SRA EXCITER ANTENNAS
The most important aspect of the entire installation is the correct positioning of the SRA Exciter An-
tenna. Take note of the following:
- Ensure that no tag can reach the protected area without passing through a field.
EXI HALO Installation Manual Rev 2.0
EXI Wireless Systems Inc. Page 8June, 1999
- 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 also 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 com-
munication 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.
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 from wall to wall. 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 ob-
jects such as pipes, cables and air plenums. The SRA may also be dropped inside a wall cavity. Some-
times 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.
Figure 5 – Antenna Field
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.
The location of the SRA is limited only by your imagination. If you have a location where you would
like to mount it, try it. If it doesn’t work, try something else. The important thing is that it must work
well in its location. Each field needs to be fully tested to ensure adequate coverage of the protected
If it’s not possible to create a proper field with the exciter
inside, an SRA-E exciter antennae for outdoors could be
placed on an outside wall to limit the penetration of the
field into the building.

area. The procedure to fully test the field is described in the “INSTALLING CONTROLLERS” sec-
tion of this manual.
2.4. KEYPAD OR PINPAD?
Each of the user interface devices provide local audible and visual alarm and bypass indication as well
as a means for the user to input requests to the system. If a staff member needs to be able to inititiate a
bypass function from either side of the door, there will have to be two user interface devices of the
same type installed. The type of device to select is dependent upon the situation and the user require-
ments.
KEYPAD – different codes for bypass and reset – everybody uses the same codes
PINPAD – different codes for bypass and reset – everybody has their own codes
2.5. LOCATING THE RECEIVER ANTENNA
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 al-
ways on the floor. Walls, equipment and excess metal could affect the pickup range. Although greater
distances are possible, a maximum of 50’between devices is recommended.
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, en-
sure that the entire area has coverage. Experience will shorten this process as the installer learns what
site conditions cause problems.
One of the issues to think about is the storage and handling of the tags when not on the patients. Tags
that are not on a “body” or stored in a proper container are periodically transmitting TIC alarms. Un-
necessary alarms can occur while cleaning Tags and when transferring a Tag to or from a patient. The
Host computer software allows the staff to put the Tag into a special status so that it will ignore all
TIC alarms coming from that Tag. However, any equipment driven by the relay outputs of the devices
will still be triggered and the staff also has to remember to put the Tag back into active status when
done. It is best to avoid the problem if at all possible.
Cleaning of the Tags could be done in a room that is outside the range of any devices. The staff may
prefer to bring a patient to a particular room to put on a Tag and then remove the Tag at the door as
they walk the patient out. The site administration people should be consulted about these issues prior
to installing the system
Watch out for foil backed ceil-
ing tile.

3. INSTALLATION PROCEDURES
3.1. INSTALLING CONTROLLERS
3.1.1. PREPARE CONTROLLER FOR FIELD SET UP
Figure 6 - HALO Controller Typical Hook-up Diagram
Assemble the controller pieces as illustrated in the above diagram. This is only a preliminary assembly
in order to set up the field. If necessary, obtain an AC extension cord so that the system may be tempo-
rarily energized at this location. Connect a user interface device such as a DKX Keypad. Make sure the
jumper on the back is in the maximum volume position so you can hear the beeper from a distance.
Check inside the controller to insure that the proper voltage is selected for the device you want to use.
PinPads use 5V while the Keypad requires 13V.
Install the RX antenna onto the Controller and plug in the R2-SRA. Try to place the RX antenna in the
approximate final location so that the test will be realistic. Open the controller cover and turn the ro-
tary Mode switch to position 0 for Test mode. In this mode the controller will turn on the beeper each
time it successfully reads a Tag. Connect the power supply and power-up. The frequency of beeping
will tell you how good the reception is.
Duct tape is metallic and
should never be used on the
SRA Exciter Antennae
The RX antennas can also be installed on a length of
coaxial cable when the best position for the antenna
is different than the best placement for the device.
The RX antenna should be oriented in the horizontal
plane with the maximum surface of the antenna ex-
posed to the longest distance requirement.

3.1.2. TEST CONTROLLER AND SET UP FIELDS
After reading Section 3.2 on LOCATION FOR SEA EXCITER ANTENNAS, choose a suitable
location for the SRA. Setting up a field is a matter of 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 test-
ing. You might want to do a preliminary field setup by holding the SRA at the approximate loca-
tion 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 all the
way to the end for maximum field range. If the device is not beeping at this point, the SRA will
need to be repositioned. Once the SRA is positioned so that the device is beeping, turn the control
shaft counter clockwise slowly until the beeping stops. Then return clockwise approximately 1/16
of a turn or so that the beeping resumes. Repeat this process for various orientations of the Tag.
Make sure the Tag can be read in any position.
Now that the field range is set up, you need to determine the shape and consistency of the field.
SOME NOTES ON SENSITIVITY: All radio frequency (RF) devices are sensitive to po-
larization. Everyone has had a portable radio that got much louder if it was positioned at a
particular angle. Another example is the TV antenna on your house. If you turned your TV
antenna on it’s side, you would receive a weaker signal and the deterioration of picture
quality would be dramatic if the TV signal you received was already marginal.
Unfortunately all other RF receivers suffer from the same electronic phenomenon. The
Roam II Tag has to first receive from the controller before it will transmit its serial number.
We can expect that there will be better response from the tag in one orientation. A strong
field will ensure that even an improperly oriented Tag will respond.
The most important aspect of the entire installation is the correct positioning of the
SRA Exciter Antenna. A little time spent here will save countless hours of frustration
and service calls later.
Apply double-backed foam tape to the side of the antenna to temporarily attach it to a
vertical surface for testing purposes. Take care that the antenna doesn’t fall as sudden
hard jolts may render it useless.
EXI HALO Installation Manual Rev 2.0
EXI Wireless Systems Inc. Page 12 June, 1999
TROUBLESHOOTING: If the controller is having trouble detecting tags, try different
positions for the RX antenna. Raising the detection THRESHOLD with the rotary switch on
the far left of the controller circuit board can remove some of the background noise as well as
reduce interference from Tags talking to nearby controllers.
Holding the tag in a closed fist, pass the Tag slowly through all the areas that you need the field to
cover twisting your wrist back and forth slowly as you move. 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.
3.1.3. 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 a small amount of “Liquid Nail”, “Firestone 500”, silicone caulk, or similar
product 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 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 7 - Securing the Exciter Antenna Cable
Mount the Controller permanently and position the RX antenna. Mount the user interface device(s)
where planned
The DKX and the PINPAD panels are designed for flush wall mounting in a standard 2-gang elec-
trical box. Should surface mounting be necessary, an optional SMB box is available. Adjust the
sound level for the beeper by moving the jumper on the back of the panel to the next set of pins
until the desired sound level is achieved. 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 remove the
Piezo and relocate it above the ceiling so the Piezo opening has a direct path into the corridor.
The Keypad installation is similar to the above except it only needs a 1-gang electrical box. Also,
there is no volume control for the beeper on the Keypad.
Install door switch. Hook up Maglock and any peripheral devices. Make sure the Maglock will re-
lease in case of a Fire Alarm.
Power up and test the field again.

With a HOST computer in the system, the recommended switch setting for the “Authorized Entry”
mode is Option 0 (No Tags are authorized). “Patient Monitoring” or “Article Surveillance”
modes should have Option 1 selected (All Tags will be stopped).
These settings let the HOST have complete control over which Tags are allowed access to or from
the protected areas. The following table shows the selected function for each switch position, de-
pending on the mode selected.

3.2. INSTALL RECEIVERS
Figure 9 – HALO Receiver
Receivers are meant for use where only a “TIC” signal needs to be detected. The “Relay” light
comes on to indicate relay activation when a “TIC” is detected. Receivers are not capable of cre-
ating a field of energy using Exciters, as Controllers can, and therefore do not have to be con-
nected to the Exciter Antennae. Install the RX Antenna onto the Receiver, place the Receiver in the
approximate location for final use, connect the power supply and power-up. Adjust the RX An-
tenna orientation for the best reception.
Figure 10 – HALO Receiver Threshold and Operating Voltage Setting
3.3. TESTING TIC ALARM COVERAGE AROUND THE BUILDING
With all devices installed at the location, ensure that a “TIC” can be detected from all remote corners
and locations of the protected area. Also ensure that the overlapping fields of detection from the vari-
ous Controller and Receiver devices are fine-tuned.

3.4. CONNECTING TO THE HOST COMPUTER
The Host Computer is included in a full-blown HALO system that needs central site monitoring and
control. The Host Computer runs the HALO Application Software that provides the following major
functions:
§ Management of the database that stores the identities of all the system components and Tags that
are deployed within the system
§ Management and storage of logs of all the alarm conditions that occur during use
§ Annunciation of any of the alarm conditions that may exist, showing location of such an alarm
condition in a graphical format overlaid over the floor plan of the building in which the system is
installed
Figure 11 – HALO Network with Host Computer
For HALO systems that only require localized alarm and control, the Host Computer may not be re-
uired.
All devices on the RS485 bus will require an RIM for Weigand to RS485 conversion. It is important
for the computer RS485 output be connected to the “PC Terminator”, and not directly to the RS485
network so as to provide the correct termination and loading required for the driver within the PC. The
R2 TAP boxes may be used to provide clean connections from the RIM to the RS485 network line.
Figure 12 – Sketch of RIM
The Host Computer consists of a Pentium based computer with a 17”
Color Monitor, a Keyboard, mouse, and Speakers for audible feed-
back. A ZIP drive is used for periodic, data backup. The ZIP disk is
removable, allowing for off-site archiving of the backed-up database.
