31.0 INTRODUCTION:AWID's Sentinel-Prox MR-1824 Reader is one of the best performing Mid-Range ProximityReaders in the industry. It has the unique combination of long read range with low powerconsumption, and in some cases, the power supply in the access control panel is sufficient topower the MR-1824. This Reader is pre-calibrated for mounting on metallic elbow stands withsimultaneous Wiegand and RS-232 outputs. Its primary applications are Access Control in ADAcompliance applications where wheelchair bound persons can activate the entrance control at aconvenient distance.1.1 General Descriptions:• Wall mount or pedestal mount reader• Indoor or outdoor installation • LED visual indicator• Audio/visual feedback1.2 Special Features:• Simultaneous Access Control (Wiegand) and Time & Attendance (RS-232) outputs• Pre-calibrated for mounting on metallic elbow stand with minimum impact on read range• Permanently sealed electronics for indoor or outdoor applications• UV stabilized plastic housing1.3 Suggested Applications• Access Control• Asset Management • Time & Attendance• RFID2.0 PRINCIPAL OF OPERATIONThis Radio Frequency Identification (RFID) reader or proximity reader uses radio frequency toidentify, locate and track people and objects that carry the appropriate transponders. Proximityreader can work in none line-of-sight situations and in darkness, bright sun light or through dirt,grimes and smudges.A typical proximity system consists of three components – an interrogator or a reader, atransponder or a card and a data processing panel and/or computer combination. Most RFIDreader has an internal micro-controller, a transmitter, a receiver and a shared transmit/receiveantenna. The card is usually passive (without an internal battery) and consists of an antennaand an RFID ASIC (Application Specific IC). During operation, the transmitter sends out anelectromagnetic wave to establish a zone of surveillance. When a card enters this zone, theelectromagnetic energy from the reader begins to energize the IC in the tag. Once the IC isenergized, it goes through an initialization process and begins to broadcast its identity. Thisprocess utilizes a low energy back-scattering technology that selectively reflects or back-scatters the electromagnetic energy back to the reader. The receiving circuits in the readersenses and decodes this back-scattered signal and hence determines the identity of the tag. AWID PROPRIETARY

The BEEP indicates that the Reader detects and reads the card. In orderto read again, the card must be fully withdrawn from the Reader’s read field and then re-approached again. During normal operation, the card can be presented at any angle relative tothe Reader, however this will result in slight variation of read range.Note: Do not "waved" the card in front of the Reader. "Waving" the card in front of theReader will cause diminishing read range.NOTE: FAILURE TO FOLLOW THE INSTALLATION GUIDE MAY RESULT IN POORPERFORMANCE OR EVEN CAUSE PERMANENT DAMAGE TO THE READER.THUS, VOIDING THE PRODUCT WARRANTY.4.0 PREPARATION FOR INSTALLATION4.1 Site Survey:Always conduct a site survey before starting installation, avoid any possible sources ofinterference. If the Reader is not installed properly, the performance will be degraded or moreseriously the Reader may be damaged. The following is a list of installation procedures thatshould be followed during installation:• Do not install the Reader in the vicinity where sources of broadband noise may exist.Examples of broadband noise sources are motors, pumps, generators, DC-AC or AC-DCconverters, non-interruptible power supplies, AC switching relays, light dimmers, CRT's,induction heater etc.• Do not let the Reader wiring bundle together in one conduit with the AC power cables,lock power, and other signal wiring. AWID PROPRIETARY
5• Keep all the Reader wiring at least 12 inches (30 cm) away from all other wiring, whichinclude but not limited to, AC power, computer data wiring, telephone wiring and wiring toelectrical locking devices.• Do not operate the reader within 36 inches (91 cm) of a computer CRT terminal.4.2 General Good Reader Installation Practice• Avoid mounting reader on large metallic surface, such as metal door or chain-link fence,or other similar environments,• Make sure that the supply voltage of the Reader is within specification. As a rule ofthumb, higher supply voltage results in longer read range (not to exceed 12V) but at theexpense of higher power consumption.• Use cables with over-all shield (Screen).• For best result, run the cable in an individual conduit with at least 12 inches distanceaway from the AC power, computer data cables and cables for electrical locking devices.• Use recommended cable. Do not use any un-shielded "Twisted Pair" type cable.• Use the largest wire gauge possible.• Use dedicated and linearly regulated power supply, where applicable.• Use Single Point Grounding (Earthing). No ground loops.4.3 Metal MountingThe Reader can be pre-calibrated for mounting on metal; for best result, avoid metallic objectaltogether. The Reader should not be framed within or surrounded by metal of any kinds. If theReader is installed in an enclosure, such as a parking station, contact AWID for sources ofappropriate fiberglass enclosures. Stands off the Reader at least 2.0 inches (5 cm) on all sidesof a metallic enclosure and do not cover up the front face.4.4 General Wiring RequirementsAll the Reader wiring must be continuously shielded. AWID recommends using #22 AWG up to#18 AWG, six or seven-conductor shielded cables. Longer distances and higher currentconsumption on the power supply line will require larger gauge wires. Refer to Table 4.4-1 andFigure 5.2-1 and Figure 5.2-2 on the following pages to determine your data lines’ wiringrequirement. Due to system data termination differences, contact your panel manufacturer fortheir specific requirements.TABLE 4.4-1: Data Line’s Wiring RequirementWIRE SIZE #22 AWG (0.6mm Dia) #18 AWG (1.2mm Dia)WEIGAND 270 ft (85 meters) 980 ft (300 meters)RS-232 45 ft (15 meters) 45 ft (15 meters) AWID PROPRIETARY
6NOTE: WHEN USING AN EXTERNAL POWER SUPPLY, ALWAYS USE A LINEAR POWERSUPPLY, DO NOT USE SWITCHING POWER SUPPLY.4.5 Power SupplyThe operating frequency of a typical switching power supply ranges from 15 KHz to 50 KHz. Itwill usually generate wideband switching noises plus some of its harmonics may fall on or near125 KHz, the operating frequency of the Reader. Therefore, avoid using a switching powersupply at all times. AVOID using a single power supply for Reader and the magnetic lock.Doing so will affect the Reader operation and can damage the Reader.4.6 GroundingGrounding is critical for proper operation of the Reader. When installing the Reader, it is crucialto assure that the earth ground is the best ground available. If you elect to use the AC mainpower ground, conduct a test by measuring its resistance relative to a known good ground, suchas a cold water pipe or a structural steel that is in direct contact with the ground. The resistanceshould be less than 50 ohms. If you find that the AC main power does not provide adequateearth ground, try using a solid connection to a cold water pipe.For multiple Readers installation, it is critical that all Readers are connected to the samegrounding system. Using different grounding systems will create secondary current paths orground loops that can affect the performance and cause damage to the Reader.4.7 Wiring DiagramsThe Reader is designed for Wiegand and RS-232 standard communication formats; use Figure5.2-1 for Wiegand format installation and Figure 5.2-2 for RS-232 format installation, and Figure5.2-3 for combined Wiegand and RS-232 installation. If an external power supply is being used,leave the Panel’s Ground and Power terminals open and connect the Reader’s Ground (Black)and 5-12VDC (Red) terminals to the external power supply.5.0 INSTALLATION PROCEDURECheck to verify that every item listed under Section 5.1 of this manual is present before startingthe installation.5.1 Parts Lista.

75.2 Installation Stepsa. Position the Reader at the appropriate mounting position.b. Drill four 7/64 (0.109)-inch holes as shown on the installation instruction.c. For mounding surface smaller than 8X8 inches: remove the top cover and drillappropriate mounting holes on the base plate of MR-1824.d. Drill one clearance hole for the cable and wiring lug.e. Guide the open end of the Panel’s control cable through the clearance hole.f. Connect the Reader and the Panel together according to Figure 5.2-1 for Wiegand formatand Figure 5.2-2 for RS-232 and Figure 5.2-3 for Wiegand/RS-232 format.5.3 Verificationa. Power up the PANEL, the LED on the Reader should show RED.b. Place a “good” card in front of the Reader and keep it in that position. The reader willgive out “ONE” audible BEEP and the LED will change from RED to AMBER momentarilyand than flashing between RED & GREEN. The reader will stay flashing until the panelsends an acknowledgement or until the card is removed from the reader. You can repeatthis action by placing the card in front of the reader after the LED turned RED.c. The reader uses an internal micro-controller to manage its many functions, and themicro-controller must be initialized properly. When the reader show evidence of mailfunctioning, turn off the reader and wait for five seconds before energize the readeragain.Fig. 5.2-1 Wring Diagram for Wiegand Output FormatFig. 5.2-2 Wiring Diagram For RS-232 Output Format AWID PROPRIETARY

Use the checklist below to identify the problem:• Is the card valid and working? - Try some different cards!• Is the reader wired correctly? - RED-BLK :5-12V, reader should work• Is the unit grounded properly? - DRAIN-EARTH: less than 50 Ohms• Is the card presented correctly? - Card face parallel to reader face• Is a power supply correct? - No switching power supply please!• Is reader voltage/current correct? - 5-12V @ 40-100mA typical• Is the environment free from electromagnetic interference? - Run cable away from otherdata carrying cables, reader away from electromagnetic interference sources! AWID PROPRIETARY
10When troubleshooting, try to identify the source of the problem to a unit level. “Is the problemfrom the panel?” Or “is the problem originated from the Reader? “ Maybe the problem “is thepower supply?”All AWID’s readers will need only a power supply and a valid card to work properly. If thereader is only connected with RED (+5-12V) and BLACK (Ground), the reader will BEEP andmomentarily turned AMBER, when a valid card is presented. If the Card stays within the readerzone of surveillance, the LED on the reader will become flashing GREEN. When the card isremoved, the LED will return to RED, signifying it has returned to stand-by mode. When thereader works according to the tests above, the reader is working properly.Do not cycle the power supply ON and OFF in rapid succession. Each power has its unique“decay” characteristics, turning the power supply ON and OFF in rapid succession can causethe Microcontroller to lock-up, due to improper initialization. Always turn the power supply OFFand count 10 seconds before turning ON again.To check the validity of the output data in the absence of a panel, you will need to build a patchcable between the reader and a PC. Call AWID’s technical support for details.If problem persists, consult the system manufacturer. If problem is the reader, consult AWID’sTechnical Assistance Department.
