Installation overview Installation overview The following steps are general instructions for installing the 94x/ 97x reader. Each step is explained in further detail in the sections that follow. 1. Mount the reader backplate. Refer to “Mounting the reader” on page 8. 2.
Some terminals radiate electrical noise that may reduce the effective maximum read range. • Never mount Models 940, 970 or 972 on or near metal. Metal effects the tuning of the reader and may severely degrade its performance, decreasing read range and increasing current draw.
Model 94x/97x Proximity Reader Installation Manual Configuring the reader Switch settings Two banks of four DIP switches located on the back of the reader are used to select the reader power level, operating mode, and beeper sound level. Please note that the location and orientation of switch block SW2 have changed for readers manufactured after December, 2002 as illustrated in Figure 10, “Model 94x/97x...

Configuring the reader trade-off between read range and cabling distance is common to all proximity badge readers. The power selection switches on the 94x/97x readers allow the optimum power setting to be selected to suit individual installations. For example: On the high power setting, giving the greatest badge read range, the reader typically requires 200mA of supply current from the microcontroller.
Configuring the reader Figure 11. (PCB Assembly P/N 100079001 manufactured prior to 12/02) CAUTION: Power should be removed from the reader while switch settings are changed.

Model 94x/97x Proximity Reader Installation Manual Selecting operating mode Field changeable DIP switches allow all 94x and 97x readers to operate in one of four distinct operating modes: Wiegand (4001), F/2F, Supervised, and Silent Supervised. In the unsupervised modes, the reader communicates with the microcontroller over a unidirectional Wiegand or F/2F data link that carries badge data only.

Testing the reader such an alarm is present, refer to the troubleshooting guide at the end of this manual. Note: In silent supervised mode, no indication of loss of supervision is provided, except badges will not be read. 7. Select a known good ProxLite test badge. Be sure the badge is properly entered in the host system, and the micro badge data format matches the reader.
Model 94x/97x Proximity Reader Installation Manual Troubleshooting the reader If the operation of a component is in doubt, substitute a known good component and retry the system. Always verify wiring against wiring diagrams before powering up the system. The troubleshooting guide is divided into three sections. The first section is applicable to all installations, the second section provides additional diagnosis for unsupervised readers, and the last section provides additional diagnosis for supervised readers.

Troubleshooting the reader None of the LEDs are on: Check that the beeper is enabled (See Table 5 “Beeper sound level DIP switch settings,” on page 27), then present a known good ProxLite test badge to the reader while listening for the beeper. If the beeper sounds, the reader is faulty and should be replaced.

Model 94x/97x Proximity Reader Installation Manual 2. Check that the reader is not mounted within 3 feet (1 meter) of a computer terminal or within 10 inches (250 mm) of another proximity reader. The only exception to this 10-inch (250 mm) limit is for 941, 971, and 973 readers installed with the optional, back-to-back, metal mounting plates.
Troubleshooting the reader Green LED turns on but the door does not open: Verify correct door strike wiring and operation. The reader is functioning properly. The beeper is always on and/or the yellow LED is off: yellow LED blinks off and the beeper sounds while a key is pressed (Models 972 and 973 only), as long as the reader DIP switches are not set to disable the beeper.

Model 94x/97x Proximity Reader Installation Manual 2. Verify that the correct pull-up resistor is installed on the microcontroller. See Figure 12, “Wiring diagram, Model 94x/97x Supervised F/2F Mode,” on page 30. 3. Verify that the microcontroller has the correct firmware for a supervised reader.
Page 47
Troubleshooting the reader 1. If multiple beeps occur regularly, refer to the installation drawings to verify that the correct pull-up resistor has been added to the microcontroller. 2. Replace the reader with one you know is working correctly. If this solves the problem, the original reader is probably faulty and should be replaced.
Model 94x/97x Proximity Reader Installation Manual Regulatory approvals UL Listed Installations Specifications for UL compliance are shown below: • Operating Temperature Range: +32 F (+0 C) to +120 F (+49 C) • Relative Humidity: 85% • The Model 94x/97x readers were evaluated by UL for indoor use only.
Model 94x/97x Proximity Reader Installation Manual CE/FCC compliance To make the Model 94x/97x reader installation CE and FCC compliant, the cable connecting the reader to the microcontroller must have its shield grounded at the microcontroller, according to one of the methods specified in the figures below. Note: Do not make shielded connections at the reader.
