SINGLE READER
EXPANSION
MODULE
The ADC-ACX1 Single Reader Expansion Module provides a
solution for interfacing to a one Wiegand reader and door
hardware. It also provides LED control and buzzer control.
Two Form-C contact relay outputs may be used to control
locking hardware. The two inputs provided can be used for
monitoring door contacts and request to exit devices.
Input circuits can be configured as unsupervised or supervised
using end of line resistors. Communication to the Alarm.com
Door Controller is accomplished using a 2-wire RS-485
interface. The ADC-ACX1 requires 12 to 24V DC for power.
