4.6 TEST RESULTS

• Proper operation of the reader and credential is indicated by a signal from the SP-6820-LR test unit each time

that the credential is read. The LED changes briefly from Standby red to green, and a short beep (4 kHz tone) is heard.

If the card or tag remains in the reader’s effective RF field, reads repeat at about 3 per second (factory default rate).

• By moving the test tag in the space in front of the LR-2000 reader, the tester can map the extent of the effective RF field

that is plotted in Figure 1. The reading distance should extend from the reader’s face to the guaranteed 10 feet or 15 feet

with the test tags. The maximum diameter of the field’s cross-section, at half of the maximum range, should be about 6 feet.

5 INSTALLING THE READER

5.1 INTRODUCTION

Before installing the long-range readers and credentials, the rest of the application system is usually in place and tested. The system

components for each entrance are commonly –

• Computer with the application program

(may be shared)

• Controller panel and reader-input module

• Gate or door operator (control and motor)

• Status switch for gate or door

• Request-to-exit switch or sensor

• Safety loop detector beyond the gate or door

• Buried loop to detect approaching vehicles

• Independent power source (not from the panel)

• Cables in conduit

These installation instructions are for the LR-2000 reader’s Wiegand interface, using Data-0 and Data-1 wires (like most readers

in access control). Note: LR-2000 wiring is not

the same as a 125 kHz proximity reader. Follow the instructions in Section 5.4.

If a serial interface using RS-232 protocol will be used, please download AWID’s Technical Reference on RS-232 Reader Interface.

5.2 INSTALLING THE LR-2000 READER

1. Before starting installation at the site, plan the project. Study Sections 9 and 10 of this Manual.

2. Keep the reader assembled. Do not remove the aluminum plate behind the reader. Do not remove the plastic cover

of the reader. Do not tighten or loosen the screws through the cover. This preserves your Warranty.

3. Attach the LR-911MB mounting bracket to the reader’s metal plate using 2 screws (1/4”-20, supplied).

4. To use a different mounting device, make an adapter plate or bracket that lets you fasten your mounting device to the

two capture nuts at the center of the reader’s aluminum plate (1/4”-20 thread). Do not drill holes through the aluminum plate.

In most applications the mounting device must allow pan-and-tilt adjustment for the reader.

5. Inspect the installation space. The reader may be mounted on any material including metal, but there must be open space

in front of the reader and to its sides. There must be no material interfering with the reader’s effective RF field

between the reader and the credentials’ location.

6. Measure the mounting height. It must relate to the location of the credentials when they are read at the “sweet spot”.

For passenger vehicles it is typically at a height of 7 feet, to the side of the vehicle lane.

7. Be aware of the environment. Stay away from UHF communications devices. Avoid arc lighting fixtures by 3 or 4 feet.

Aim neighboring readers so that their effective RF fields do not overlap. Mount readers for parallel lanes at least 12 feet

apart, with their effective RF fields parallel to each other. Do not have LR-2000 readers facing each other

(but “back-to-back” is OK). If mounted outdoors, provide a shield for sunlight and rain.

8. Test the site for electronic devices that may interfere with the LR-2000 reader. If interference is suspected, remove power

from the other device while observing the LR-2000 reader’s performance.

9. Fasten the reader’s adjustable bracket or housing to the pole, post, pedestal, wall or ceiling.

10. Aim the reader at the location of the credentials (cards or tags) in the vehicle, when the credentials are at their reading distance

from the reader. AWID guarantees minimum reading distance for its UHF credentials of 10 feet to 15 feet, depending upon

the credential type. When the credentials are at this “sweet spot”, the reader and the credentials should be about parallel to

each other.
