As far as I know a notification (SendNotification) doesn't ring.

Are you talking about an Alert ? A Sound ?

You have to use Time or Bar to stop repeat ringing

you can learn more from this example in mql5 and attempt to write in mql4:

int OnCalculate(const int rates_total,
                const int prev_calculated,
                const datetime &time[],

                const long &volume[],
                const int &spread[])
  {
//---
   ArraySetAsSeries(time,true);
   //Print(time[0]);

   static datetime pastime = time[0];
   if(pastime!=time[0])
     {
      // Add your code for Send Notification which will trigger only once when a new bar occurs
      pastime=time[0];
     }
   
//--- return value of prev_calculated for next call
   return(rates_total);
  }
