An alarm condition will not shut down the engine. However, an alarm may precede a shutdown. An alarm indicates a serious condition that requires immediate attention. If an alarm condition occurs, the alarm module uses an indicator and a horn to inform the operator. There are several different types of alarm modules that are available. Alarm modules are optional. The features of the alarm module are identified in Illustration 6.
