Mullion Reader (ADC-AC-ET10) - Installation Guide
The Mullion Reader (ADC-AC-ET10) offers a modern aesthetic and a state-of-the-art feature set. Standard
technologies include Proximity (125 kHz), NFC (13.56 MHz), and Bluetooth. The Mullion Reader is fully OSDP compliant
and is enabled for Secure Channel.
Additionally, the reader offers a patented feature called OSDP Auto-Detect. The reader communicates OSDP and
Wiegand over the same wires to automatically detect and convert to OSDP Secure Channel protocol, eliminating the
need to rewire or reconfigure the reader.
Mount the wall plate
Drill two mounting holes at a minimum of 1.7" apart. Drill a ½" hole in the center for the pigtail wire to pass through. Use
the wall plate as a guide for drilling.
Wire the reader
