AWID's Sentinel-Prox Proximity Reader NDK-2025LF is a
non-destructible reader with integrated 12-key keypad for PIN number
input in a durable metal housing.
NDK-2025 is designed for high-security applications that require
dual verification
in vandal, tamper and weather proof environments. With a read range
of 2 to 2.5 inches, the NDK-2025 delivers exceptional value without
compromise on quality,
durability, and performance for both indoor and outdoor
applications.
The NDK-2025 reader is a fully featured Wiegand and RS-232
compatible reader with an LED
and Enunciator for both small and large volume OEM and Dealer
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 NDK-2025's attractive enclosure comes in silver color. Its
electronics are
potted in UL-approved epoxy resin potting compound to seal them
against adverse environmental
conditions. It is manufactured in an ISO 9001:2000
certified facility providing for
the highest quality standard.
When a valid card/tag is presented within the reader's field, the
reader's LED momentarily turns
AMBER and the 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 card reads
from a single card presentation.
