EXI HALO Installation Manual Rev 2.0EXI Wireless Systems Inc. Page 5June, 19991. INTRODUCTION1.1. Intended AudienceThis manual serves as a guide for Installers of the HALO system. The major components of the systemare described, as well as the system’s intended functionality, so as to gain familiarity with its operationprior to installation. In order to successfully install and commission the system, it is absolutely criticalto 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 HALOTags. 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 OPERATIONThe EXI HALO system uses Radio Frequency waves for communications between the HALO systemcomponents and the Tags. The HALO Controller continuously emits a 307 kHz RF frequency via theExciter Antenna, setting up a field in its local area. When a Tag enters this field, a Radio Receiverwithin the Tag senses the 307 kHz RF field and transmits its identification information to the HALOController using a low level Radio Signal at frequency of 434 MHz.Figure 1 - Controller OperationRECEIVEANTENNA RBCFCC ID# HE7MAXTRANSMIT OUTPUTSEA #1 SEA #2Made in Canada . . with care ControllerbyPower1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20+24V DC InputSystem Ground+12V Ou 200 maSystem GroundWeigand 0/DataWeigand 1/GndSystem GroundMagOut 24V 200 maDoor Switch InSystem GroundUnlock InOverride InStrobe InN.OCOMN.C.N.OCOMN.CRelay #1 Relay #2Alarm InOFF ONEXI ELECTRONIC SYSTEMSWinnipeg, Manitoba (204) 788-1696Made in CanadaPRODUCTMODEL NO.SERIAL NO>ROAM II/TAGRRRSEA-M1118HALO ControllerRXAntenna SRAExciterAntenna434 MHz 307 KHzTransponder
EXI HALO Installation Manual Rev 2.0EXI Wireless Systems Inc. Page 6June, 19992. DECISIONS TO MAKE PRIOR TO INSTALLATION2.1. SYSTEM WIRINGThe HALO network is based on the RS-485 electrical interface standard, which is 2-wire multi-nodebus. The EXI HALO elements are designed such that many more than the RS-485 limit of 32 Driversand 32 Receivers can be co-exist on the same network. The baud rate used in the HALO system is57,600 bps, and therefore in order to avoid data corruption it is important to ensure that a clean signalis always present. Using the right type of cable, network topology, and not exceeding total cable lengthare critical factors in ensuring that the system will operate reliably.Figure 2 - "Bus" Topology Figure 3 - "Star TopologyCable 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 networkshould 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, aRS-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 mainsystem to minimize noise pick-up and loading of the system. Cables used in Elevator shafts should bestranded and not solid, and should be resilient enough to withstand the continuous flexing that it willexperience for many years in the elevator shaft.Figure 4 - Typical HALO ConfigurationR2 RECEIVERDATACOMM.Made in Canada . . with care12/24 VDCGROUNDDATA 0DATA 1N/O 1COM 1N/C 1N/O 2COM 2N/C 21 2 3 4 5 6 7 8 9 10POWER RELAYController 1WhipAntenna ExciterAntennaHALO NetworkRECEIVEANTENNA RBCFCC ID# HE7MAXTRANSMIT OUTPUTSEA #1 SEA #2Made in Canada . . with care ControllerbyPower1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20+24V DC InputSystem Ground+12V Ou 200 maSystem GroundWeigand 0/DataWeigand 1/GndSystem GroundMagOut 24V 200 maDoor Switch InSystem GroundUnlock InOverride InStrobe InN.OCOMN.C.N.OCOMN.CRelay #1 Relay #2Alarm InOFF ONEXI ELECTRONIC SYSTEMSWinnipeg, Manitoba (204) 788-1696Made in CanadaPRODUCTMODEL NO.SERIAL NO>ROAM II/TAGRRRSEA-M1118Controller 2WhipAntennaExciterAntennaRECEIVEANTENNA RBCFCC ID# HE7MAXTRANSMIT OUTPUTSEA #1 SEA #2Made in Canada . . with care ControllerbyPower1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20+24V DC InputSystem Ground+12V Ou 200 maSystem GroundWeigand 0/DataWeigand 1/GndSystem GroundMagOut 24V 200 maDoor Switch InSystem GroundUnlock InOverride InStrobe InN.OCOMN.C.N.OCOMN.CRelay #1 Relay #2Alarm InOFF ONWinnipeg, Manitoba (204) 788-1696Made in CanadaPRODUCTMODEL NO.SERIAL NO>ROAM II/TAGRRRSEA-M1118RIMRIMReceiver 1WhipAntennaRIMRS485 BusTAPTAPTAPPCTerminatorRS-485Repeater Elevator ControllerRIM

CONTROLLER CONFIGURATIONSThe HALO controller handles all communication with the Tags, provides audible and visual indicatorsof what state its in and prevents egress when necessary. The controller chassis may be horizontally orvertically mounted, on a wall, ceiling or shelf and should be mounted so that the front face panel iseasily accessible. Since it is preferable to leave the RX antenna attached directly to the controller, theexact location of the controller will affect the reception of the tags and should only be finalized aftersetting 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 provideseasy access to a number of different output formats as well as allowing inputs to alter some of itsautomatic 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 ORPINPAD?The Tag serial numbers as well as status information is output in Weigand format on 2 of the outputpins. This is a standard format used by many Card Access Systems. The MagOut line will engage aMagnetic Door Lock when Tag’s are detected in the field. Due to NFPA 101 regulations beingadopted in many locations, it may be mandatory to provide an automatic door release with 15 secondsafter 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 TagInitiated 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-supervisedAnnunciator- EXI model “APEX”, supervised Annunciator system through inputs ofan APEX I/O-8Contact 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 centralsystem, no alarms are annunciated until the door opens. At that time, all the Tags are re-read by thecontroller so that only the Tags that are still in the field will cause an alarm. The door switch is alsouseful during bypass as the controller will detect the door opening and then terminate the bypass assoon 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 thedoor with the local and remote alarm annunciators on. Override In will disable the controller so thatno tags are read and nothing will be reported to the Host computer. Shorting the appropriate line toground 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 ANTENNASThe 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 occupiedby tags. These tags could keep a controller in a pre-alarm state preventing thedoor 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 themagnetic 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 torespond to both controllers. Each controller will see Tag communication when itdoesn’t expect it and report it as noise.Ceiling height, door approach width and metal in the vicinity, need to be considered when planning thelocation for the exciter antennae. The field should extend to the floor and from wall to wall. A droppedceiling consisting of a grid and non-foil backed ceiling tile are the easiest construction materials towork 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 5feet from the floor.Extensive metal close to the Exciter can distort the field in unpredictable ways. Metallic objects willabsorb and/or reflect radiated energy, which affects the field. This phenomenon can increase or decreasethe field strength in areas causing hot spots or holes in your field. It can even change the shape of thefield with tag detection sometimes occurring as much as 35 ft away. At times this effect can be used toadvantage 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, someinformation about the field will help to shorten the process of determining the best location for theSRA. In the absence of any site irregularities, the field is symmetrical perpendicular to the antennalength. A cross-section through the length of the antenna is roughly oval as shown below.Figure 5 – Antenna FieldAlthough the field strength is adjustable, the maximum distance for good coverage is approximately 10feet. 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 wouldlike to mount it, try it. If it doesn’t work, try something else. The important thing is that it must workwell in its location. Each field needs to be fully tested to ensure adequate coverage of the protectedIf it’s not possible to create a proper field with the exciterinside, an SRA-E exciter antennae for outdoors could beplaced on an outside wall to limit the penetration of thefield into the building.
EXI HALO Installation Manual Rev 2.0EXI Wireless Systems Inc. Page 9June, 1999area. 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 wellas a means for the user to input requests to the system. If a staff member needs to be able to inititiate abypass function from either side of the door, there will have to be two user interface devices of thesame 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 codesPINPAD – different codes for bypass and reset – everybody has their own codes2.5. LOCATING THE RECEIVER ANTENNAThe area to be protected has to be blanketed by controllers and receivers so that all critical areas havecoverage. 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 greaterdistances 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 althoughsome metal objects may enhance communication by reflecting the signal further than it would normallytransmit. Wire glass sometimes found around nurseries can cut down the range. The only way to besure 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 whatsite conditions cause problems.One of the issues to think about is the storage and handling of the tags when not on the patients. Tagsthat 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. TheHost computer software allows the staff to put the Tag into a special status so that it will ignore allTIC alarms coming from that Tag. However, any equipment driven by the relay outputs of the deviceswill still be triggered and the staff also has to remember to put the Tag back into active status whendone. 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 mayprefer to bring a patient to a particular room to put on a Tag and then remove the Tag at the door asthey walk the patient out. The site administration people should be consulted about these issues priorto installing the systemWatch out for foil backed ceil-ing tile.

PREPARE CONTROLLER FOR FIELD SET UPFigure 6 - HALO Controller Typical Hook-up DiagramAssemble the controller pieces as illustrated in the above diagram. This is only a preliminary assemblyin 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 thejumper 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 theapproximate 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 eachtime it successfully reads a Tag. Connect the power supply and power-up. The frequency of beepingwill tell you how good the reception is.Duct tape is metallic andshould never be used on theSRA Exciter AntennaeThe RX antennas can also be installed on a length ofcoaxial cable when the best position for the antennais different than the best placement for the device.The RX antenna should be oriented in the horizontalplane with the maximum surface of the antenna ex-posed to the longest distance requirement.EXI ELECTRONIC SYSTEMSWinnipeg, Manitoba (204) 788-1696Made in CanadaPRODUCTMODEL NO.SERIAL NO>ROAM II/TAGRRRSEA-M1118"RX" AntennaKeypad "SRA"Exciter AntennaHALO "Controller"1 2 34 5 67 8 9*0#Optional, toEnhamce CoverageRECEIVEANTENNA RBCFCC ID# HE7MAXTRANSMIT OUTPUTSEA #1 SEA #2Made in Canada . . with care ControllerbyPower1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20+24V DC InputSystem Ground+12V Ou 200 maSystem GroundWeigand 0/DataWeigand 1/GndSystem GroundMagOut 24V 200 maDoor Switch InSystem GroundUnlock InOverride InStrobe InN.OCOMN.C.N.OCOMN.CRelay #1 Relay #2Alarm InOFF ON
EXI HALO Installation Manual Rev 2.0EXI Wireless Systems Inc. Page 11 June, 19993.1.2. TEST CONTROLLER AND SET UP FIELDSAfter reading Section 3.2 on LOCATION FOR SEA EXCITER ANTENNAS, choose a suitablelocation for the SRA. Setting up a field is a matter of trial and error. The primary considerationshere are the field shape and strength. The field has to fill the area in front of the door all the way tothe 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 isusually going to be found. The tag needs to be detected far enough from the door to allow themagnetic 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 shouldbe temporarily placed and the field adjusted for range using this stationary tag. Since the Tag willbe read easier in some orientations with respect to the SRA, it is also necessary to test with the Tagin a variety of positions.With the SRA and tag in position use the SRA RANGE ADJUST control on the top right corner ofthe controller circuit board to set up your field strength. Turn the control shaft clockwise all theway to the end for maximum field range. If the device is not beeping at this point, the SRA willneed to be repositioned. Once the SRA is positioned so that the device is beeping, turn the controlshaft counter clockwise slowly until the beeping stops. Then return clockwise approximately 1/16of 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 aparticular angle. Another example is the TV antenna on your house. If you turned your TVantenna on it’s side, you would receive a weaker signal and the deterioration of picturequality would be dramatic if the TV signal you received was already marginal.Unfortunately all other RF receivers suffer from the same electronic phenomenon. TheRoam 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 strongfield will ensure that even an improperly oriented Tag will respond.The most important aspect of the entire installation is the correct positioning of theSRA Exciter Antenna. A little time spent here will save countless hours of frustrationand service calls later.Apply double-backed foam tape to the side of the antenna to temporarily attach it to avertical surface for testing purposes. Take care that the antenna doesn’t fall as suddenhard 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 differentpositions for the RX antenna. Raising the detection THRESHOLD with the rotary switch onthe far left of the controller circuit board can remove some of the background noise as well asreduce 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 tocover twisting your wrist back and forth slowly as you move. DON”T FORGET DOWN BYTHE FLOOR. The device should continue to beep at a steady rate. An uneven rate indicates thatthe controller is not able to read the tag successfully every time. The final step is to ensure that thefield does not extend into other rooms or areas that are regularly occupied by tags. These tagscould inadvertently keep a controller in an alarm state. 3.1.3. FINALIZE CONTROLLER INSTALLATIONFasten SRA exciter antenna. If installing the SRA above a ceiling tile, use a marker pen to draw anoutline of the SRA in its desired position on the upper side of the tile. Once you are certain of theSRA location, use a small amount of “Liquid Nail”, “Firestone 500”, silicone caulk, or similarproduct to cement the SRA to the tile, preventing it from falling on the floor should the tile belifted 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 solow that it touches the bottom steel plate. Loop the coax cable and wrap a band of electrical tapearound it as shown below. Ensure the SRA will hang at the correct height by marking the cableprior to dropping the SRA inside the wall. Secure the cable when the SRA is hanging in the correctposition.Figure 7 - Securing the Exciter Antenna CableMount the Controller permanently and position the RX antenna. Mount the user interface device(s)where plannedThe 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 thesound level for the beeper by moving the jumper on the back of the panel to the next set of pinsuntil 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 thePiezo 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.EXI ELECTRONIC SYSTEMSWinnipeg, Manitoba (204) 788-1696Made in CanadaPRODUCTMODEL NO.SERIAL NO>ROAM II/TAGRRRSEA-M1118

INSTALL RECEIVERSFigure 9 – HALO ReceiverReceivers are meant for use where only a “TIC” signal needs to be detected. The “Relay” lightcomes 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 theapproximate 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 Setting3.3. TESTING TIC ALARM COVERAGE AROUND THE BUILDINGWith all devices installed at the location, ensure that a “TIC” can be detected from all remote cornersand locations of the protected area. Also ensure that the overlapping fields of detection from the vari-ous Controller and Receiver devices are fine-tuned."RX" Antenna12/24 V DCHALO "Receiver"R2 RECEIVERDATACOMM.Made in Canada . . with care12/24 VDCGROUNDDATA 0DATA 1N/O 1COM 1N/C 1N/O 2COM 2N/C 21 2 3 4 5 6 7 8 9 10POWER RELAYEXI ELECTRONIC SYSTEMSWinnipeg, Manitoba (204) 788-1696Made in CanadaPRODUCTMODEL NO.SERIAL NO>ROAM II/TAGRRRRECEIVER1119RECEIVERANTENNABack ViewFront View“Threshold”Switch1224

CONNECTING TO THE HOST COMPUTERThe Host Computer is included in a full-blown HALO system that needs central site monitoring andcontrol. The Host Computer runs the HALO Application Software that provides the following majorfunctions:§ Management of the database that stores the identities of all the system components and Tags thatare 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 alarmcondition in a graphical format overlaid over the floor plan of the building in which the system isinstalledFigure 11 – HALO Network with Host ComputerFor 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 importantfor the computer RS485 output be connected to the “PC Terminator”, and not directly to the RS485network so as to provide the correct termination and loading required for the driver within the PC. TheR2 TAP boxes may be used to provide clean connections from the RIM to the RS485 network line.Figure 12 – Sketch of RIMThe 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 isremovable, allowing for off-site archiving of the backed-up database.R2 RECEIVERDATACOMM.Made in Canada . . with care12/24 VDCGROUNDDATA 0DATA 1N/O 1COM 1N/C 1N/O 2COM 2N/C 21 2 3 4 5 6 7 8 9 10POWER RELAYController 1WhipAntenna ExciterAntennaHALO NetworkRECEIVEANTENNA RBCFCC ID# HE7MAXTRANSMIT OUTPUTSEA #1 SEA #2Made in Canada . . with care ControllerbyPower1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20+24V DC InputSystem Ground+12V Ou 200 maSystem GroundWeigand 0/DataWeigand 1/GndSystem GroundMagOut 24V 200 maDoor Switch InSystem GroundUnlock InOverride InStrobe InN.OCOMN.C.N.OCOMN.CRelay #1 Relay #2Alarm InOFF ONEXI ELECTRONIC SYSTEMSWinnipeg, Manitoba (204) 788-1696Made in CanadaPRODUCTMODEL NO.SERIAL NO>ROAM II/TAGRRRSEA-M1118Controller 2WhipAntennaExciterAntennaRECEIVEANTENNA RBCFCC ID# HE7MAXTRANSMIT OUTPUTSEA #1 SEA #2Made in Canada . . with care ControllerbyPower1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20+24V DC InputSystem Ground+12V Ou 200 maSystem GroundWeigand 0/DataWeigand 1/GndSystem GroundMagOut 24V 200 maDoor Switch InSystem GroundUnlock InOverride InStrobe InN.OCOMN.C.N.OCOMN.CRelay #1 Relay #2Alarm InOFF ONWinnipeg, Manitoba (204) 788-1696Made in CanadaPRODUCTMODEL NO.SERIAL NO>ROAM II/TAGRRRSEA-M1118RIMRIMReceiver 1WhipAntennaRIMRS485 BusTAPTAPTAPPCTerminatorRS-485RepeaterElevator ControllerRIM
