7.4Setup System - Setup Common Alarm

The audible alarm sounds after the Liebert AC4 detects an alarm condition in any input that has been defined as alarmable. Once the alarm is silenced, there are two options:

•By default, the common alarm remains energized until all input alarms are cleared.

•You may change this setting to de-energize the common alarm automatically once the alarm is silenced.

You might want to reset the common alarm with silence if an external alarm—for example, a horn—is connected to the common alarm output contacts.

You might not want to reset the common alarm contacts (let contacts reflect/track alarms) and simply silence the audible horn.

To change the common alarm setting:

Log In and Choose Setup System

•From the Main Menu, use the arrows ↑↓ to choose System and Control, then press Enter ↵ (see 7.1 Login for help).

•Enter your password at the Login screen.

•From the System and Control Menu, use the arrows ↑↓ to choose Setup System, then press Enter ↵.

Change to Reset (Y) or Not Reset (N)

•From the Setup System Menu, shown at right, use the arrows ↑↓ to choose Setup Common Alarm and press Enter ↵.

•By default, the common alarm is set up not to reset automatically when the alarm is silenced (N). To change this setting, use the arrows ↑↓ to choose Y (Yes - reset with silence) or N (No - not reset), then press Enter ↵.
