Installation The card reader is designed to fit perfectly on the 1-3/4 inch standard metal door frame or window mullion. The metal compensation that is built into every card reader assures minimal loss of read range when the reader is mounted on a metal surface. The card reader also can be fastened by 2 screws on any wall or other surface. Installation may be indoors or outdoors, exposed to weather.

The card reader contains a 3-color LED and a 4 kilohertz beeper. Both LED and beeper are controlled by the reader itself, and also can be controlled externally by the host system. The LED can indicate accessgranted by the host. The beeper can be used as an alarm that prevents further card reads until the alarm condition is cleared.

Testing The reader is self-testing using its own LED and beeper, it needs no interface to a controller to assure the installer and cardholder of correct performance. The reader is also selfdiagnostic if DC power is unstable, or if electrical noise is induced in the cable, the reader resets and its LED changes to amber. Operation i3s proximity readers use a re-present mode that requires that the user remove the card from the readers field before the card can be read again. This feature eliminates multiple reads from a single presentation of the card. The reader has both Wiegand data interface for basic 4-wire connection (6 wires when all features are controlled), and also RS-232 serial interface. Code transmission from both interfaces is simultaneous.

The card reader is ready for challenging applications. The ABS plastic onepart enclosure, fully potted at the back surface with epoxy resin, stands up to physical abuse and adverse environment. Credentials All of i3s 125 kilohertz proximity credentials may be used with the card reader. This includes clamshell and graphics-quality cards, keytags, hangtags and adhesive wafers. Read range varies with the credential type.
