The audible alarm sounds after the 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
