Alarm settings worksheet
The alarm settings for your SEC-HD determine which alarm conditions are enabled, which are
disabled, and their settings. All these work together to determine how and when the alarm relay
activates (in other words, signals an alarm condition).
The alarm relay activates if an enabled alarm condition is present for longer than the minimum
duration of one minute. The minimum duration prevents alarms from occurring when the
temperature rises or drops for just a few seconds. The exception to the one-minute minimum is the
power fail alarm. The power fail alarm automatically triggers the relay on a loss of power.
For more information, read Programming alarm settings on page 35.
