Actually, the behavior that you desire is the way it should working "out-of-the-box".  Check the <node-outage> element in your poller-configuration.  It should look like:

   <node-outage status="on" pollAllIfNoCriticalServiceDefined="true">
      <critical-service name="ICMP"/>
   </node-outage>

That configuration should make OpenNMS generate only a single Node Down event and alarm for all services on all IP interfaces if the critical service (or all services if no critical service) is down on all interfaces.  There will be outage records recorded for each service but only one Node Down event/alarm.
