how to clean the splunk alarm?

Hello, expert,

I set up an alarm as following, and run it as cronjob by 5mins. Do you have any idea on clean the alarm only after the alarm occurs to avoid sending alert every 5mins in normal situation?

| eval alarm = if(value >= alarmTheashold,1,0)        //if alarm==1, then tag=1
| eval clear = if(value <  alarmTheashold,1,0)         // clear=1 when value<alarmTheashold AND tag==1

Sorry, maybe I'm not descript clearly. The issue is if alarm happens in 5 mins before, then I need to test the threshold. If condition match then sent a clear alarm out, otherwise, I don't need to do anything.
