2 Acknowledging Alarms

Purpose of Audio / Visual Alarms

Audio / Visual alarm annunciators are designed to alert you of a problem so appropriate

and immediate corrective action can be taken. An overview of alarms and indications

will proceed the main topic of this chapter — Acknowledging Alarms. Once you are familiar

with these you can go directly to the Acknowledging Alarms topic.

Audio Alarm Annunciator (& Output Relays)

The Alarm annunciator horn and relay outputs #1 and # 2 are output devices that are

located within the console. Output devices are controlled (switched on / off) by one or more

output groups. One or more warnings / limits / alarms are programmed to an Output

Group, which control the output devices (see below).

The annunciator horn can be programmed to produce a continuous (solid) tone, or a

modulated (beeping) tone. Certain warning or alarm conditions can use a unique tone to

signal when these events have occurred.

Optionally, external alarm devices can be activated when they are wired to the console

alarm-relay-output # 1 or # 2.

These three output devices can also be programmed to silence or deactivate when a

certain time-out value is reached. This alarm time-out feature is used (programmed) when

an Alarm Acknowledge password is required before an alarm can be silenced. See Chapter

1 about how to use the ACK SHIFT key.
