USING THE ALARM CONNECTIONS AND ACO BUTTON

Introduction

The alarm connections alert the user when a selected alarm condition exists. The alarm may be cleared by pressing the Alarm Cut-Off (ACO) switch on the front panel of the ATLAS 550. This procedure details the steps which must be performed to use the ATLAS 550 alarm connections and 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-014).
