To measure the read range between the Reader and the transponder, the transponder must be placed behind a piece of glass about 0.25 inches thick and the transponder must be flat against the glass. Grasp the transponder by the edges and hold the transponder so that the copper circuit faces the Reader. Move the transponder toward the Reader, with the card surface parallel to the Reader, until a BEEP occurs (using the SP-6820-LR test unit). The BEEP indicates that the Reader detects and reads the transponder. Optional firmware allows the user to select read repetition rates of about 3 per second, 1 per second, or 1 per 3 seconds. NOTE: FAILURE TO FOLLOW THE INSTALLATION GUIDE MAY RESULT IN POOR PERFORMANCE OR EVEN CAUSE PERMANENT DAMAGE TO THE READER, THUS VOIDS THE PRODUCT WARRANTY. AWID PROPRIETARY Page 8 9/26/2007 LR-911 2.6H3 3.1 PREPARATION FOR INSTALLATION SITE SURVEY Always conduct a site survey before starting installation. Avoid any possible sources of interference. If the reader is not installed properly, the performance will be degraded or more seriously the reader may get damaged. Listed below are steps that should be followed during installation: • Do not install reader in an area where sources of broadband electromagnetic noise may exist. Avoid mounting the reader facing a cellular phone tower or in close proximity to the base station of a 900 MHz wireless telephone. • Keep all of the Reader wiring at least 12 inches (30 cm) away from all other wiring, including, but not limited to, AC power, computer data wiring, telephone wiring, and wiring to electrical locking devices. • Do not operate the reader in close proximity to other 900 MHz wireless equipment/devices. 3.2 PREFERRED READER INSTALLATION PRACTICES • Avoid mounting the reader under direct sunlight. Exposure to direct sunlight may cause the reader to operate at a temperature above the 65 degrees Celsius upper limit. • Make sure that the supply voltage of the reader is within specification • Use cables with over-all braid or shield • For best results, run the cable in an individual conduit, in safe distance from AC power, computer cables and cables for electrical locking devices • Use recommended cable. Do not use any unshielded Twisted Pair type cable • Use the largest wire gauge where feasible • Use dedicated power supply, where necessary • Use Single Point Grounding (Earthing) for block wire of cable. No ground loops. Outer shield of cable should not be grounded. 3.3 MOUNTING PREFERENCE The LR-911 has a uni-directional antenna with an antenna beam width of about 60-70 degrees. The radiation pattern is an oval-shaped beam, which should be aimed toward where the transponders will pass. For best results, the antenna should be mounted on a post; about 6 to 7 feet from pavement with the antenna angled slightly downward. With a vehicle passing through the drive lane, the center of the antenna radiation pattern should project to the windshield directly in front of the passenger or driver. Install Readers for neighboring vehicle lanes so that the effective areas for detecting tags do not intersect. Only one Reader should be able to read a tag at any location of AWID PROPRIETARY Page 9 9/26/2007 LR-911 2.6H3 the tag. Be sure to elevate the antenna slightly to accommodate sport utility vehicles, minivans and trucks. 3.4 GENERAL WIRING REQUIREMENTS All the reader wiring should be continuously shielded. AWID recommends using #22 AWG up to #18 AWG, longer distances and higher current consumption on the power supply line will require larger gauge wires. Due to system data termination differences, contact your panel manufacturer for the proper wire sizes to meet their specific requirements. TABLE 3.4-1: Data Line’s Wiring Requirement WIRE SIZE WIEGAND RS-232 #22 AWG (0.6 mm Dia.) 500 ft (152 meters) 50 ft (15 meters) #18 AWG (0.5 mm Dia.) 980 ft (300 meters) 50 ft (15 meters) NOTE: WHEN USING AN EXTERNAL POWER SUPPLY, USE A HIGH-QUALITY POWER SUPPLY THAT MEETS THE CURRENT SPECIFICATION (SECTION 2). 3.5 POWER SUPPLY For consistent performance, choose a high-efficiency switching power supply with remote sense and use the voltage sense wire to ensure consistent performance. Alternatively, use a linear, regulated power supply with sufficient current capacity (see Section 2, Specifications). 3.6 GROUNDING Grounding is critical for proper operation of LR-911. When installing the reader, it is crucial to assure that the earth ground is the best ground available. If you elect to use the AC main power ground, conduct a test by measuring its resistance relative to a known good ground, such as a cold water pipe or structural steel that is in direct contact with the ground. The resistance should be less than 50 ohms. If the AC main power is found not to provide adequate earth ground, try using a solid connection to a cold water pipe. Outer shield of cable should not be grounded. For multiple LR-911 installations, it is critical that all units are connected to the same grounding system. Using different grounding systems will create secondary current paths or ground loops that can affect the performance and cause damage to LR-911. 3.7 WIRING DIAGRAMS See Figure 1 for wiring using Wiegand output to the host panel, Figure 2 for using RS232 to the control device, or Figure 3 for a combination of them. AWID PROPRIETARY Page 10 9/26/2007 LR-911 2.6H3 The Reader’s Blue wire is Signal Ground. It must be connected to the signal-return at the panel or reader-input module. This is commonly (but not always) the panel ground terminal. Figure 1 Figure 2 Wiegand Output Format RS-232 Output Format The Reader’s Yellow wire enables the Reader to function only when this line is pulled low (0 V) by a dry contact or by connection to ground. The Yellow wire must be connected to either (a) a vehicle-sensing switch (if used), which is at ground potential AWID PROPRIETARY Page 11 9/26/2007 LR-911 2.6H3 when a vehicle is present, or (b) a permanent ground, for example, the Reader’s black wire. Figure 3 RS-232 & Wiegand Output Format AWID PROPRIETARY Page 12 9/26/2007 LR-911 2.6H3 INSTALLATION PROCEDURE Verify that all items listed in section 4.1 of this manual are present before starting the installation. 4.1 PARTS LIST a. Installation Instructions (packed inside Reader carton) Qty=1 b. Sentinel-Prox LR-911 Reader Qty=1 (Tags for the LR-911 Reader and Installation Kit are available separately) 4.2 INSTALLATION STEPS a. Locate the Reader (Item b on Parts List) at the desired mounting position on a mounting post or a mounting surface. For mounting on a flat surface, drill four small holes through the aluminum plate behind the Reader housing for mounting screws, and one clearance hole for reader cable. For flexible mounting, use a video camera adjustable mount or clamps. The installer determines the size of the mounting holes and the clearance hole. b. Install the tags on the selected surface, for example, inside vehicle windshields or on the side of bins, pallets, truck trailers, etc. c. Use the LR Installation Kit to provide audible and visible feedback as the tags are attached and the Reader is aimed at the tags. d. For Wiegand output, connect the Reader and the Panel together by cable according to Figure 1. For RS-232 data format, see Figure 2. For simultaneous outputs, see Figure 3. 4.3 VERIFICATION a. Connect the SP-6820-LR test unit, which is part of the LR Installation Kit, to the Reader cable. Use the wiring list in the Installation Instructions. Apply power to the reader and the test unit, using the plug-in DC power module in the Installation Kit. b. Use either a Prox-Linc WS tag that is attached firmly by its adhesive to a rectangle of windshield glass, or a Prox-Linc MT tag for verification. Hold the tag so that the hand does not interfere with direct line-of-sight between the tag and the Reader. c. Move the tag into the field. Observing the SR-6820-LR test unit, there is a brief LED color change and a beep to indicate each read of the tag by the Reader. Reads will repeat at a rate that is determined by the Reader’s firmware. d. Move the tag from side to side, and at varying distances from the front of the Reader housing, to determine the space in which the tag and Reader are active. 4.4 MOUNTING AWID PROPRIETARY Page 13 9/26/2007 LR-911 2.6H3 a. Check to ensure that all connections are secure. Feed all wires through the cable access hole to the rear or the side of the mounting position. b. Mount the Reader using fasteners on the aluminum plate to which the LR-911 Reader is attached. Drill holes through the plate as required by the application, or attach flexible mounting devices or clamps. c. Adjust the position or the angle of the Reader so that the tags (which have been fastened by adhesive to the windshield or other surface) are detected and read at the desired distance from the Reader.
