Power fail The alarm settings for your SEC DC 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 one minute minimum duration prevents alarms from occurring when the temperature rises or drops for just a few seconds For example the high temperature alarm setting is 85 0 F If the temperature rises to 86 degrees but drops below 85 degrees 30 seconds later the alarm relay does not activate If the temperature rises to 86 degrees and stays there for more than 1 minute the alarm relay activates The alarm relay remains activated until the temperature drops below the alarm setting 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 When an alarm occurs the Alarm LED switches on and the alarm message displays For more information about acknowledging and responding to alarms read Acknowledging alarms on page 34 Use temperature override to test your high and low temperature alarms instead of adjusting the group set point In temperature override mode the alarm relay and status LEDs both operate as if they were in a real alarm situation For more information rea
