The outside housing is made of stainless steel and is beveled such that it is nearly impossible to get sufficient leverage to pry it off a wall or mullion. The portion of the face of the reader that covers the electronics consists of many layers of interwoven fiberglass that is UL 752 listed for bulletproof integrity. The reader can withstand 9mm bullets at a “point-blank” firing range and will not be burned by common cigarette lighters, both which are typical sources of vandalism. Many applications do not lend themselves to concealment of a reader inside or behind a wall, so the reader must be exposed to the environment. Exposed readers traditionally have invited vandalism, resulting in higher cost to the building owner because of constant replacement, inconvenience and lack of security for users due to system down time. The NXT 4R is field proven in its ability to function in open, hostile environments. The NXT 4R is for use exclusively with Keri’s revolutionary access control system based on the NXT Series of IP- based Controllers. With an allowable cabling distance of 1,000 feet from the controller and using just 4-conductor or shielded CAT-5 cable, the NXT 4R dramatically reduces cabling costs when compared to traditional 6 or 7 conductor reader interfaces. Encrypting identification data between the card and reader and supervising the reader from the controller to check for failure provides the most secure reader solution available. The NXT 4R is compatible with all NXT Series Cards and Tags.
