Description AWID's Sentinel-Prox™ Proximity Reader SP-6820- GR-MP is specially suited for applications where a discriminating look makes a difference. An attractive package which looks great outside the boardroom or at the front gate in the rain or snow. With a read range of up to 8 inches, the SP-6820-GR-MP delivers exceptional value without compromise on quality, durability, or performance for both indoor and outdoor applications. The SP-6820-GR-MP reader is a fully featured Wiegand and RS-232 compatible reader with an LED and Annunciator for both small and large installations. It is designed to mount on a standard-single-gang electric wall-box or on the surface of an interior or exterior wall. The SP-6820-GR-MP's attractive enclosure comes in a dark gray color. The SP-6820-GR-MP's electronics and antenna are encapsulated in an UL-approved epoxy resin potting compound to seal them against adverse environmental conditions. When a valid card/tag is presented within the reader's field, the reader's LED momentarily turns AMBER and beeper sounds to indicate that a data transmission took place. If the card/tag stays within the reader's field, the LED will blink RED/GREEN to indicate that the reader is functioning properly. The reader has a re-present mode in which the card must be taken from the reader field before being read again. This feature eliminates multiple reads from a single card presentation.
