General Information

is the basis for a completely autonomous access
control system for one gate or door. Although technologically
sophisticated, it is quick and simple to use, as well as compact
and flexible in application. The N-300
uses proximity detection
techniques to sense the presence of a unique tag allowing the
automatic opening or unlocking of a door, gate or other access.
The tag is a small, self-contained, automatic identification
device, usually in the shape of a key tag or card.
The N-300 consists of a compact, surface mounted access
control unit containing an internal stand-alone reader. The
system is programmed using programming cards or an optional
hand-held programmer.
The N-300 has the advantage of proximity detection which
does not require physical contact between ID reader and ID-
carrier. The tag functions without use of a battery. The ID
reader scans the ID-carrier by means of a long wave radio
frequency transmission. If the tag is within range, it is activated
and powered by this signal and in return transmits its specific
ID number. This technique ensures easy to use, highly reliable,
vandal-proof access control.
