You just need to add another condition. For example, check to see if a global variable "pinging" equals 1
and when you don't want it to ping just set "pinging" to 0
alternatively, you could just disable the group that it's in.
The text visibility will be checked on every single tick.. and moving on to the next condition it will then check to see if ten seconds have elapsed since the first time the action/ping happened. If so it will ping again.
