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).
Tools and Materials Required
• VT100 terminal or PC with VT100 terminal emulation software
To prevent electrical shock, do not install equipment in a wet location or during a
lightning storm.
Electronic modules can be damaged by static electrical discharge. Before handling
modules, wear an antistatic discharge wrist strap to prevent damage to electronic
components. Place modules in antistatic packing material when transporting or storing.
When working on modules, always place them on an approved antistatic mat that is
electrically grounded
