Alarms are the result of one or more error conditions. Four alarms are available and each may have any combination of errors assigned to it. These result in actions based on settings in the ALARM ACTION panel.

The ALARM SETUP panel has 4 columns, each corresponding to one of the 4 alarms. Each row of the panel corresponds to one type of detected error. Checking the box at the intersection of an error row with an alarm column enables that type of error to cause the numbered alarm. The Sentinel front panel ALARM indicator displays this numeric error code.
