Access Control

Card reader

by Mark Rowe

The new AR10S-MF/AR40S-MF card readers for the SiPass access control system from Siemens work with Mifare Classic, Mifare Plus and Mifare DESFire EV1 cards. When used with Mifare Classic and Mifare DESFire EV1 cards, encryption technology is employed between the card and the card reader. All communication between the card reader and the host system can be encrypted, delivering security, the makers add. The card readers are also ready for near field communication (NFC) standards which allow for contactless communication.

The basic version is a straight card reader. Other versions incorporate an integrated keyboard and an OLED display that can show system alerts and messages. Both the keypad and display are illuminated and their brightness automatically adapts to the ambient light. All versions have an LED frame which can be illuminated in red, yellow or green.

The card readers are available for surface and flush mounting. They clip to a backplate or recessed box that has been previously installed and can be removed only using a key. This feature is according to the makers particularly useful in new buildings where the backplates and recessed boxes can be installed in the rough-in stage and the readers attached only when the building is ready for occupancy.

Surface-mount versions have an IK08 impact protection rating, making them it is claimed resistant to vandalism. With an ingress protection rating of IP55 and an operating temperature range of minus 40 degrees C to plus 55 degrees C, they are the company says a choice for indoor and outdoor applications.
