The MR50 Single Reader Expansion Module is designed to add one extra reader to an Alarm.com door controller. Each ADC-AC-MR50 adds one reader port, two relay outputs, and two programmable inputs to the system. Connect the expansion module to the controller using a shielded, RS-485 twisted pair. For larger commercial installations, Single and Two Reader Expansion Modules can be daisy-chained together.
