1.0 INTRODUCTION: AWID's Sentinel-Prox MR-1824 Reader is one of the best performing Mid-Range Proximity Readers in the industry. It has the unique combination of long read range with low power consumption, and in some cases, the power supply in the access control panel is sufficient to power the MR-1824. This Reader is pre-calibrated for mounting on metallic elbow stands with simultaneous Wiegand and RS-232 outputs.

• Keep all the Reader wiring at least 12 inches (30 cm) away from all other wiring, which include but not limited to, AC power, computer data wiring, telephone wiring and wiring to electrical locking devices. • Do not operate the reader within 36 inches (91 cm) of a computer CRT terminal. 4.
NOTE: WHEN USING AN EXTERNAL POWER SUPPLY, ALWAYS USE A LINEAR POWER SUPPLY, DO NOT USE SWITCHING POWER SUPPLY. 4.5 Power Supply The operating frequency of a typical switching power supply ranges from 15 KHz to 50 KHz. It will usually generate wideband switching noises plus some of its harmonics may fall on or near 125 KHz, the operating frequency of the Reader. Therefore, avoid using a switching power supply at all times. AVOID using a single power supply for Reader and the magnetic lock.
5.2 Installation Steps a. 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 drill appropriate 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.
Fig. 5.
5.4 Mounting a. Checks to ensure all connections are secured. Feed all wires through the cable access hole to the rear of mounting plate. b. Mount the Reader with the #6-32x1” Thread-cutting screw, Type 23 (Item c on Parts List). c. Insert the Screw hole plug (Item d on Parts List) into the screw clearance holes to conceal the screws. Note: screw hole plugs are designed for one-time use only! Once the plug are seated, they can not be removed without damaging the plugs. 6.
When troubleshooting, try to identify the source of the problem to a unit level. “Is the problem from the panel?” Or “is the problem originated from the Reader? “ Maybe the problem “is the power supply?” All AWID’s readers will need only a power supply and a valid card to work properly. If the reader is only connected with RED (+5-12V) and BLACK (Ground), the reader will BEEP and momentarily turned AMBER, when a valid card is presented.
