Akuvox ACR-CRM11 Metal Keypad Card Reader (Wiegand)

The Akuvox ACR-CRM11 is not a standalone access device: it is a reader that sends what it reads to an Akuvox door phone, access terminal or controller over Wiegand. That makes it the part used when a door needs a second reading point, such as a reader on the inside for exit, a reader at a car gate wired back to the door phone's controller, or extra doors on an Akuvox A094S or A095S controller.

It reads both card families common in Kuwait, 125 kHz EM proximity cards and 13.56 MHz Mifare cards, and its numeric keypad lets users enter a PIN code, so cards and codes registered on the Akuvox system work at this reader too.

The M in CRM stands for metal: the front is aluminium and rated IP65, so it can be fitted outdoors on a gate post or a wall, and its slim 138 × 58 × 22 mm body suits door frames. It runs on 12V DC and has a buzzer and a status light to confirm each read.

Wiring is the standard Wiegand set (D0, D1 and ground) plus power, and Akuvox's guide shows the reader connected to an A094 controller. For a lower-cost plastic version, see the ACR-CRP11.
