Proximity Card Reader (Wiegand) Technical Reference Manual AC-1200 IInnssttaallllaattiioonn The AC-1200 is supplied complete with a 12 length of 8-core shielded cable that is used to connect the reader to the controlling device. The cable cores have a cross-sectional area of 0.22 mm2, which is the approximate equivalent of size 24 AWG. Installation of the AC-1200 includes the following tasks, which are detailed in the sections to follow:
Prepare to mount the reader Connect the cable to the host Wiegand interface Connect the power supply cabling Mount the reader Note: To Prevent EMI between readers, ensure the readers are mounted at least 6 apart. The cable is integrated into the AC-1200 circuitry, which is sealed in a protective resin potting. The multi-core shielded cable is connected to a terminal block on the AC-3151 door controller. The following procedure is used when the cables are connected to the terminal block:
The terminal block is removed from the controller PCB 1/4 of the insulation is carefully stripped from the end of each conductor The terminal screw is loosened The bare portion of the conductor is inserted into the terminal orifice The terminal screw is fastened The recommended screwdriver is a slot-head type screwdriver suitable for size 0 or size 1 screws (3/32 wide blade). The screws should not be over-tightened as this may damage the conductor. Mounting The AC-1200 proximity card reader can be mounted against most surfaces, including metal. Two, 0.2 diameter mounting holes are countersunk into the front of the housing. Screws and wall anchors are provided with the unit. Copyright KeyMatrix Inc.. All rights reserved.

Card reader dimensions When mounting the AC-1200 proximity reader, the following procedure is used:
Position the reader where it is to be mounted Mark the positions of the mounting holes on the mounting surface Drill holes in the mounting surface using a suitable drill bit of the correct gauge Drill a hole for the cable feed if necessary Feed the cable through the mounting surface to the door controller Connect the cable to the terminal block of the door controller, as detailed in the following section Insert wall anchors into the holes if necessary Align the reader with the holes and fasten the mounting screws For proper operation, it is best not to subject the AC-1200 proximity card reader to excessive heat, moisture, vibration or electrical interference. For back-to-back operation (opposite sides of a door) always maintain a minimum distance of 6 between the two card readers. A suitably grounded metal shield may be inserted between the back-to-back readers to reduce undesirable crosstalk. Copyright KeyMatrix Inc.. All rights reserved. p. 6 Revision C [2005-11-04]
Proximity Card Reader (Wiegand) Technical Reference Manual AC-1200 Wiegand interface The AC-1200 reader is connected to one of the two Wiegand interfaces on the AC-3151 reader interface module or the single Wiegand interface on the AC-2010 operator station. The AC-3151 Wiegand interfaces consist of eight-way, press-in terminal blocks which are easily removed and connected to the cores of the reader cable, as shown in the diagram below. 0 0 2 1

C A Typical card reader wiring to AC-3151 Reader Interface Module The cabling route between the AC-1200 reader and the host device shall not exceed 25 yards when powered by the host device. The recommended cabling type for the Wiegand interface is an 8-core, Mylar screened cable with size 24 AWG conductors. In cases where the supplied cable needs to be extended up to 25 yards, Belden P/N 9538 or equivalent 24AWG 4-pair, shielded cable may be used. Cable junctions shall be performed in accordance with the National Electrical Code and must not bear tension. Copyright KeyMatrix Inc.. All rights reserved. Revision C [2005-11-04]

p. 9 Proximity Card Reader (Wiegand) Technical Reference Manual AC-1200 DC power supply For installations where the AC-1200 is in close proximity to the door controller (< 25 yards), it is recommended that the DC power for the AC-1200 unit be taken directly from the host device Wiegand port. For longer distances, use a separate dc power supply. The UL294 Listed, power-limited power supply must be able to deliver a minimum current of 200 mA at 12 Vdc under all conditions. When using separate power supplies, the negative or ground rail of all the power supplies must be referenced to the ground of one of the supplies to ensure common ground reference.

Proximity Card Reader (Wiegand) Technical Reference Manual AC-1200 DDiiaaggnnoossttiicc SSttaattuuss IInnddiiccaattoorrss The AC-1200 card reader includes a tri-color LED indicator that can emit red, green or amber light. The reader also has a piezo buzzer set in the resin at the rear of the unit. When 12 Vdc power is applied to the AC-1200 reader, the LED flashes amber and the buzzer emits a short tone. When successful communication with the controller is established, the LED continuously flashes green at one-second intervals. When a proximity card is successfully read by the AC-1200, the buzzer sounds. The LED and buzzer are under the control of the host device and are used to indicate normal access control events and to diagnose card reader malfunction. The status of an access control transaction is indicated by the LED; green for access allowed and red for access denied. The following table describes the various states of the LED and buzzer for assistance in the diagnosis of typical reader behaviour:
