Please Note: The Alarm.com CD-410-US-AT Interlogix Concord 4 dual-path communicator has been discontinued and replaced by the 600-1053-LTE-AT model number.
The Alarm.com CD-410-US-AT is a dual-path LTE alarm communicator designed to send Concord 4 panel alarm signals over the AT&T LTE cellular towers. Eliminate your phone line bill, and add redundant dual communication paths with the CD-410-US-AT to your existing Interlogix Concord 4 security system.
