They are used to trigger an alarm at an egress point, pin point a tag’s location, and/or provide a reference point for when the tag changes floors via a stairwell or elevator. The Tag Exciter transmits a 125 KHz low frequency signal (field) that is detected by the RFID tag. Detection range of the Tag Exciter is adjustable from two to 18 feet. This section describes the two steps to installing the Tag Exciter: Determine the best location Install device. Determine Best Location The location of the Tag Exciter is critical to the proper operation of the system. An incorrectly placed tag exciter may cause nuisance alarms from nearby areas where tags are normally present, or fail to detect a tag when exiting through a doorway. NOTE: Only 2 TEs may be associated with a TRC in the Argus software or with an AtGuard Controller when configuring a gate. The Tag Exciter field can be visualized as a large sphere with the tag exciter in the centre of the sphere. As the Tag Exciter level is increased, so does the size of the sphere. The sphere ranges from 2 to 19 feet in diameter according to the setting. When a tag enters the exciter field, the Tag Exciter field is detected by the tag and events are generated by this action. An event may be an exit warning or alarm. For networked applications a Tag Exciter may be used for transitioning a tag from the previous floorplan to the present floorplan when moving vertically through a building, or trigger a custom event such as direction of travel (using 2 or more tag exciters). It should be placed in a location where the exciter field is only generated in the areas where you would like the tag to be detected. ©2010 GuardRFID Proprietary and Confidential Tag Exciter Installation Manual 07‐00051‐110 Environmental and Location Considerations Do not mount Tag Exciter directly on metal – such as elevator cars. Use ½ inch nylon or plastic spacers between the Tag Exciter and the metal surface. Mounting the Tag exciter directly on metal will detune the transmitting antennas. Do not mount Tag Exciter in a location where there is metal between the Tag Exciter and the intended tag detection area such as on top of an elevator car or behind a metal door. RF does not propagate well through the metal, causing the tag to not see the exciter field. Tag Exciter Metal Tag Consider traffic patterns and legitimate/acceptable tag locations when installing the Tag Exciter. As an example, the best location (shown below) creates a tag exciter field in direct proximity of the protected door, while at the same time maintains a suitable distance from the unprotected doors and rooms adjacent to the stairwell where tags are allowed to be located. ©2010 GuardRFID Proprietary and Confidential Tag Exciter Installation Manual Poor Location – Exciter field crosses traffic path and enters into adjacent room Up Best Location – Exciter field does not enter into adjacent rooms 07‐00051‐110 Normal Traffic Pattern YES NO Protected Door ©2010 GuardRFID Unprotected Door Proprietary and Confidential Tag Exciter Installation Manual 07‐00051‐110 Install Tag Exciter in the location that creates the smallest, most compact field. Ceiling Tag Exciter Not recommended ‐ poor floor discrimination. Tag Exciter may bleed through upper floor. Plenum Space Dropped Ceiling Ideal location – directly adjacent to the latch side of the door PRO ‐‐ creates the smallest, most compact field. CON ‐ more prone to damage or tampering ‐ may not meet the facility aesthetic requirements. Better location‐ Approx 8 or 9 feet from floor PRO ‐ hidden from view CON ‐ creates a large field – can be prone to upper floor bleed. Best location Inches above the door frame PRO‐ creates a smaller, more compact field. Floor ©2010 GuardRFID Proprietary and Confidential Tag Exciter Installation Manual 07‐00051‐110 Using Tag Exciters to Determine Direction of Travel and Room Discrimination Two or more Tag Exciters may be used to determine direction of travel through a portal, thereby identifying precisely the location and the moment in time a tag transfers from one zone to another. To determine direction of travel using tag exciters, you must understand how the Argus system treats zones. During software configuration, zones are defined on a floorplan by outlining the zone with a border. Adjacent zones are defined by drawing zones with adjacent borders. The Tag Exciters, identified by their serial numbers are then dragged onto the floorplan in the exact locations they are installed. In the simplest example two tag exciters are used. One tag exciter is installed in the first zone and the second Tag Exciter installed in the second zone directly adjacent to the first. When a tag enters the first tag exciter field, its location is pinpointed at the perimeter of the first zone. As it crosses over to the second zone, the tag will be immediately pinpointed at the perimeter of the second zone at the exact time it crossed over. Multiple tag exciters may be placed in either zone to accommodate various floorplan configurations. Keep in mind a few basic rules. 1. The tag must clearly enter a Tag Exciter field in the first zone without being in a tag exciter field located in the second zone. 2. The tag must clearly exit from a Tag Exciter field in the second zone without being in a tag exciter field located in the first zone. 3. Tag Exciter fields in either zone may overlap slightly 4. More than one Tag Exciter may be used in either zone to cover wide areas or prevent tags from slipping by undetected. Study the examples below to determine the best tag exciter locations for your application. Example A –determining direction of travel and zone transference in a corridor. ©2010 GuardRFID Proprietary and Confidential Tag Exciter Installation Manual 07‐00051‐110 Example B Determining direction of travel and zone transference to a wide area. Note the traffic patterns in this example. Two tag exciters tuned for a larger field are installed on one side of the doorway to capture tags as they disperse to different areas of the building. Tag Exciters are located to ensure the tag enters into one field and clearly transitions to the field(s) in the adjacent zone. ©2010 GuardRFID Proprietary and Confidential Tag Exciter Installation Manual 07‐00051‐110 Example C Room Discrimination As a tag enters a zone/room the tag will remain located in that zone/room until it enters another zone/room or crosses the Tag Exciter into zone 14. Note: if a tag leaves a zone/room and does not enter another room or cross the Tag Exciter to zone 14, the system can relocate the tag in the corridor using RSSI data obtained from tag reader receivers. ©2010 GuardRFID Proprietary and Confidential Tag Exciter Installation Manual 07‐00051‐110 Connecting the Tag Exciter The purpose of this section is to outline the general operation and wiring of the Tag Exciter (TE). Tag Exciters have three main functions. They are used to trigger an alarm at an egress point, pin point a tag’s location, and/or provide a reference point for when the tag changes floors via a stairwell or elevator. The Tag Exciter transmits a 125 KHz low frequency signal (field) that is detected by the RFID tag. Detection range of the Tag Exciter is adjustable from two to 18 feet.

Note that the TE connects to the network using a 433MHz link to the TRC and does not require a TCP/IP connection. PoE Powered TEs do not use the data component of the PoE switch. When powering the TE with a PoE Switch, ensure to use the recommended PoE Splitter (GuardRFID P/N 61‐24002). PoE voltage is 48VDC from the switch and needs to be converted to 12VDC to prevent damage to the TRC. Connect the TE to 12VDC / 1A power source either from the PoE Splitter or a 12VDC central power supply as shown below. Power supply voltage for the TE must not exceed 14VDC. Ensuring Compliance with RFI Rules and Regulations In order to ensure compliance with relevant RFI rules and regulations, the cable used to supply power for Tag Exciter must have ferrite suppressor attached. The ferrite suppressor is supplied with Tag Exciter and should be clamped onto the power cable as close as possible to Tag Exciter enclosure. The part number of ferrite suppressor is BF1835, manufactured by API Delevan Inc. Any equivalent ferrite suppressor can be used. ©2010 GuardRFID Proprietary and Confidential Tag Exciter Installation Manual 07‐00051‐110 Using the TE Disable (Door In) The TE LF field can be disabled by adding a switch to the Door In input of the Tag Exciter. This feature can be used when you require the field to be switched on and off quickly. The example below illustrates connection to a N/C door switch (door closed/contact closed). ©2010 GuardRFID Proprietary and Confidential Tag Exciter Installation Manual 07‐00051‐110 Tuning the Tag Exciter The purpose of this section is to show how to tune the Tag Exciter for optimal coverage in your application. The Tag Exciter field can be visualized as a large sphere with the tag exciter in the centre of the sphere. As the Tag Exciter level is increased, so is the size of the sphere. The sphere ranges from 2 to 18 feet in diameter according to the setting. Adjustments for the tag exciter include LF Field size, Changing the ID number (electronic serial number transmitted in the beacon), RF sensitivity (not field adjustable), and mode settings User Interface The TE User interface allows you access to the TE menu and adjustment tools. ©2010 GuardRFID Proprietary and Confidential Tag Exciter Installation Manual 07‐00051‐110 User Interface Menu Navigation The user interface is accessed by pressing any key.

The TE field is adjusted in the same manner for all applications. Testing the TE field size and adjusting for the desired detection area is critical to proper operation of some systems. Care must be taken when adjusting the TE field size to ensure it will detect a tag exiting through a door but not exceedingly large so that it intrudes on adjoining rooms or areas where you do not want tags to be detected. This section assumes that the TE is used at a door to detect a tag as it passes through the doorway. ©2010 GuardRFID Proprietary and Confidential Tag Exciter Installation Manual 07‐00051‐110 To test and coarse adjust the size of the LF field Press the TEST key Holding a tag in front of you, approach the doorway with a tag at waist level, the TE will beep when the tag enters the field Using the LF field adjustment instructions above, adjust the TE field size to the desired level, ensuring the tag is detected every time, and does not detect tags in unwanted areas. Holding the tag one or two inches from the floor, approach the doorway ensuring the TE beeps when the tag passes through the doorway Press the TEST key to revert back to normal operation (after 10 minutes of no key presses, TEST mode is automatically turned off Note that the tag orientation may have an effect on the apparent size of the field. Inside the tag is a coil antenna. When this antenna is parallel to one of the coil antennas in the TE, the field appears to be larger than if the two coils are perpendicular. The variation in distance varies from one foot to four feet for larger fields. Ensure that the tag is detected in all orientations. Test and fine adjust the size of the LF field To perform this test and adjustment procedure, the gate must be configured in the Argus Configuration Manager, and a keypad must be associated to the gate you are testing. Holding a tag in front of you, with the door closed, approach the doorway with a tag at waist level, the keypad will beep when the tag enters the field Using the LF field adjustment instructions above, adjust the TE field size to the desired level, ensuring the tag is detected every time, and does not detect tags in unwanted areas. Holding the tag one or two inches from the floor, approach the doorway ensuring the keypad beeps when the tag passes through the doorway Setting the Tag Exciter ID Each TE is programmed with a unique ID number which is also the serial number of the TE. The TE transmits a beacon message to the TRC that contains tag in field information, Firmware revision information and the serial number. The transmitted serial number is truncated, stripping off the most significant 13 bits of the ID. Due to the most significant bits being truncated from the ID there is a possibility of two TEs to transmit the same ID. To resolve this issue, the least significant 4 bits of the TE may be changed in the field with the tag exciter ID setting. ©2010 GuardRFID Proprietary and Confidential Tag Exciter Installation Manual 07‐00051‐110 If two TEs are transmitting duplicate Ids the least significant 4 bits of the ID number can be changed. To change the transmitted ID Press any key to activate the user interface Press the SEL key twice, or until the ID LED is lit Press the INC key until the readout displays the desired least significant digit of the ID. (i.e. 003A40 would be changed to 003A41 if the ID was changed to 1. Press the SEL key to select the least significant digit Press the ENT key to save the selected value in TE memory Setting the RF Sensitivity RF sensitivity is pre‐programmed during manufacture and this setting is not used. Setting the Modes There are three modes that are programmable, exciter field on/off, UHF board presence, and end of line resistor presence (at Door In connector). The default settings are exciter field on, UHF board present, and no end of line resistor required. These settings are not normally adjusted. Entering MODE setting configuration Press any key to activate the user interface Press the SEL key 3 times or until the MODE LED is lit – the display will go blank Press and HOLD the SEL key once more until 2 beeps are heard – the display will show “0” when the key is released The TE is now in MODE setting configuration Press SEL to scroll between mode 0, 1 and 2 Setting the TE field on/off (MODE “0”) Default – TE field ON Press select while in mode setting configuration until the readout reads “0” Press the INC key to toggle the field on and off , the field is on when the decimal point after the display is lit, off when the decimal is off (the MOD LED will flash when the setting is being adjusted) Press the ENT key to save the selected value in TE memory (the MOD LED will stop flashing) Setting the TE to activate the UHF radio (MODE “1”) ©2010 GuardRFID Proprietary and Confidential Tag Exciter Installation Manual 07‐00051‐110 Default – Radio activated – (Note: the AtGuard system does not have a radio board on the TE and will ship defaulted as “radio deactivated”) Press select while in mode setting configuration until the readout reads “1” Press the INC key to toggle activate/deactivate the radio. The radio is activated when the decimal point after the display is lit, deactivated when the decimal is off (the MOD LED will flash when the setting is being adjusted) Press the ENT key to save the selected value in TE memory (the MOD LED will stop flashing) Setting the TE to detect EOL (end of line) Resistors (MODE “2”) Default – EOL resistors not installed Press select while in mode setting configuration until the readout reads “2” Press the INC key to toggle detect/ignore EOL resistors. EOL resistors are detected when the decimal point after the display is lit, ignored when the decimal is off (the MOD LED will flash when the setting is being adjusted) Press the ENT key to save the selected value in TE memory (the MOD LED will stop flashing) Reading the Error Codes If the Alarm LED is flashing the TE has detected an error. Error codes are read from the TE display To read the error codes Press any key to activate the user interface Press the SEL key four times, or until the ERROR LED is lit Read the display: 0 – No error 1 – Case open / tamper. To simulate the cover on hold your hand at the level of the cover, near the centre of the TE and the “1” error should stop. Since the case is open when troubleshooting, this error is always displayed. You must simulate the cover on to continue. 2 – Radio not detected. The radio board is faulty or not installed (Note: In the AtGuard system there is no radio board) 3 – Input power too low. Check the input voltage; it should be 12 – 13.6 VDC 4 – Input power too high. Check the input voltage; it should be 12 – 13.6 VDC ©2010 GuardRFID Proprietary and Confidential
