The Device Alarm module provides the ability to latch Input 1 through Input n. If any of the latched results of Input 1 through Input n are in an alarm condition, then the Output is Alarm and the Maintenance Switch is set to Disable. When the latched results of Input 1 through Input n are Normal, then the Output is Normal.

When Setup n is set to Automatic, the latched result of Input n is set to Alarm when the input is at Alarm. The latched result is set to Normal when the input is Normal.

When Setup n is Manual, the latched result is set to Alarm when the input is at Alarm. The latched result is set to Normal when the input is Normal and the Reset n input is Reset. Figure 1 graphically conveys the behavior of the Device Alarm module for an instance defined for four devices.
