28. rd Reader User Manual Appendix B For all of the card types it is essential to get the correct type of card for the reader and also for the specific requirement As this involves bit patterns site codes and frequencies in the case of proximity cards it is advisable to contact us before ordering The cards should ideally be ordered at the same time as the hardware to avoid confusion It is also worth noting that the lead time on security cards is not inconsiderable typically 10 weeks Security cards can also be ordered with custom artworks but as this adds to delivery time and cost it is essential to discuss this prior to ordering The technology used for proximity cards is very different to the Wiegand technology In this case the communication between card and reader is via radio waves so called RFID and thus no physical contact between card and reader is needed for a card to be read The card need only be held close to the reader head for a successful read to take place This also allows the card to bea variety of different types e g key fobs as there is no card swipe necessary For most card types the proximity reader also provides an extra digital input which is used to indicate a card s presence This is frequently dictated by site requirements but where the card type not predetermined then in our opinion we suggest EM cards for the Far East HID for the USA and MIFARE in the rest of the world Page 35 o
29. rea Sentry Although designed to be used in hazardous areas the Sentry is equally suitable for non hazardous area use The combination of a robust design long distance communications digital inputs proximity detectors and digital outputs make its use sensible for other harsh rather than hazardous area uses In this case many of the constraints imposed by hazardous area equipment legislation can be disregarded making system connection altogether simpler Drawing number P174 116 shows the system connection for this configuration see Appendix A Page 24 of 37 Sentry IS Card Reader User Manual Option 6 Sentry IS Card Reader User Manual The major difference is that devices can be connected direct to the Sentry s RS485 422 terminals rather than through a barrier of any kind Similarly input output devices can be connected directly to the Sentry as long as the power requirements can be met without recourse to either flame proof boxes and safety characteristics The only other requirement for the safe area Sentry is a power supply of 24V at 100mA Wiegand D1 D0 Output Mode The Sentry can be ordered from the factory with different firmware that provides a Wiegand output mode specifically designed for when a hazardous area card reader is required to interface with a traditional security and access control system The operation of the Sentry in Wiegand D1 D0 Output mode is entirely different from any of the serial commu
