17413 v1.0 Document No. nnnnnnn(c) PAC 2000. Confidential PAC International Ltd. Low Profile DualTech Reader Installation Instructions Part Numbers 20467 (Black) and 20473 (White) Introduction The PAC Low Profile DualTech Reader is a proximity reader. This means that no physical contact is required between the ID device and the reader for the ID device to be read. It usually works with a door controller to control access through a door. In this case, to open a door, an ID device is presented to the reader, the reader passes the code to the door controller, and the door controller validates the code and unlocks the door. DualTech PAC produces two categories of ID device, PAC and KeyPAC series format, these are based on different reading technologies. Readers are available which read either just PAC Format format or just KeyPAC Format format, however, the PAC DualTech reader is capable of reading both. Compatible ID Devices This reader can read PAC and KeyPAC Format ID-devices. 2 This manual is correct at the time of going to press. However, as part of our ongoing product enhancement program we reserve the right to make changes to the product and/or literature at any time without prior notice to the customer. Unpacking Check that all the parts are supplied with your reader. If anything is missing or damaged, contact your suppliers immediately. The readers are each supplied with the following: 2 x 1” no.6 self tapping screws Label Ten cable crimps MOV Mounting backplate Installation Locating the Reader Be aware of the following when you choose the location of your reader: • The cable distance from controller to reader should never exceed 3000ft (1000m) (PAC equipment only with the appropriate cable, see later). Consult the specification of the chosen lock to ensure that the maximum distance from controller to lock is acceptable. • If you use a Request To Exit (RTE) switch, route the wiring so that it is not accessible if the reader is removed. • Ensure that the LED is visible to the keyholder, avoid mounting the reader in direct sunlight. • The best place for a reader is next to the door on the unhinged side at roughly the same height as the door handle. • Readers may be located inside or outside, no special protection is needed for readers mounted outside although corrosion resistant fixings should be used. • Leave enough room behind the reader for the flying lead. • Readers can be mounted behind a non-metallic material, such as glass, plastic or wood without affecting their reading range. • There should be a minimum 1-metre distance between readers (this includes in and out readers on opposite sides of a door). Cable Lengths and Wire Gauges (PAC Equipment Only) When locating the reader you also need to consider the maximum cable distance to the control equipment. The following table provides a summary for PAC door controllers only. Cable GaugeDistance (reader to PAC door controller) 7/0.20.22 mm²24 AWGUp to 750 feet (250 metres) 16/0.20.5 mm²20 AWGUp to 1500 feet (500 metres) 32/0.21.0 mm² 18 AWGUp to 3000 feet (1000 metres) If you use 24AWG (0.22mm²) cable, you should twist the wires and double them over before inserting them in the crimps. 3 Fixing the Reader 1.4” 1.4” 1.08” 1.08” 1.28” 1.28” 0.4” 0.16” 0.4” 0.4” 0.4” 0.72” 0.16” 0.32” 0.16” 0.16” 0.32” 3.28” 0.64” 3.8” This reader comes in two parts, the reader itself and the backplate. The backplate has a rubber spacer at the rear. Fixing the Reader 1. The cable from the controller should be routed through the aperture in the backplate. Leave enough cable exposed to allow easy wiring of the reader. Note: There is limited room between the reader and backplate. You should ensure there is a void large enough behind the backplate to accommodate any excess on the cable. 2. Fix the backplate to a flat surface using the No.6 screws provided - or a fixing suitable for the material to which the reader is being mounted. The two holes are 2.4 inches (60mm) apart. Use the top (round) hole first, and the lower (oval) hole to ensure the reader is straight. 3. Ensure that the reader cable is not connected to the controller. Wire the reader to the cable as described in this datasheet and in the door controller Installation Manual 4. Push the reader, with the LED to the top, onto the backplate, the fixing tabs on each side should snap into place. 5. Place label on front of reader. Removing the Reader The reader can be removed by placing a small flat-bladed screwdriver into the apertures at the edges of the snap-fit cover. Take care not to damage the reader or cover. General Tips • The cable distance from controller to reader should never exceed 3000ft (1000m). • If using a Request to Exit switch, ensure that the wiring is not accessible if the reader is removed. • Ensure that the LED is always visible to the keyholder. • Do not mount in close proximity to metals. ReaderMounting Plate 4 Wiring All connections are made to the flying lead using the 10 cable crimps provided. Cable gauge depends on distance from the Door Controller to Reader. The flying lead is 3 ft (1m) long and has a gauge 24AWG (0.22mm 2 ). With 24AWG (0.22mm 2 ) cable twist the wires and double them over before inserting them in the crimps. This includes the flying lead.

Cover Letter(s)

Covering letter for FCC Form 731 Attachments 0.459 Request that submitted material be withheld from Public Inspection FCC ID OQL-PAC-D-LPConfirmation number EA99513 It is requested that the following exhibits be withheld from Public Inspection: • Operational Description • Schematic Diagram • Internal Photos This information is considered to be PAC International proprietary and confidential. The unit is supplied fully encapsulated in hard potting - the design features are not evident from inspection hence reverse engineering is extremely problematic. This unit is believed to have a performance advantage over our competition – revealing details of the design to our competitors would put us at a disadvantage. We therefore request that the above-listed items are withheld from public inspection. Shaun Byr ne Controller Team Leader PAC International Ltd

Note 2: The correction factor of –80dB to convert from field measured at 3m to field at 300m is taken from 47 CFR 15.31 f (2) (page 661, 10-1-99 edition) which states that an inverse linear distance extrapolation factor of 40dB/decade can be used. There are 2 decades of distance from 3m to 300m, therefore the extrapolation factor is –2x40 = -80dB
