Keri Systems - Nxt-kpk - Nxt-6rk & Nxt-rm3
NXT Readers provide a number of advantages over traditional Wiegand-output readers: They communicate via RS-485, and so are supervised by the controller so that you always know their status Cabling distance from the controller is doubled - up to 1000 ft (300m) - providing more flexibility in installation Installers are able to use shielded Cat5/6 cable, thus reducing the cost of installation NXT Readers can now be ordered as "In" or "Out" readers when used with NXT Controllers (Mercury-Powered versions), which doubles the controller's reader capacity. For "Out" readers, specify model numbers with an E at end of model number (i.e., NXT-3RE).
Keri's NXT-6RK is the newest member of the NXT Series Proximity Reader family. The NXT-6RK may be mounted directly to standard U. S. A. sized single-gang wall boxes, and is ideal for applications requiring an access credential and/or personal identification number (PIN), such as high security dual verification. It connects to an NXT Controller via the NXT-RM-3 Reader Interface Module to allow the Wiegand format keypad data to be read by the controller while at the same time reading standard NXT formatted cards.
