ATLAS 550 System Manual - Adtran

DLP-15 Using the Alarm Connections and the ACO Button
Introduction
Alarm connections alert the user when a selected alarm condition exists. Pressing the Alarm Cut-Off
(ACO) switch on the front panel of the ATLAS 550 clears the alarm. This procedure details the steps which
must be performed to use the ATLAS 550 alarm connections and the ACO switch.
This procedure should be performed at installation on each ATLAS 550 shelf that is wired out to external
office alarm equipment.
Prerequisite Procedures
Before beginning this procedure, the ATLAS 550 should be mounted in its permanent location and the
alarm contacts should be connected (see DLP-14, Connecting the Alarm Contacts).
