Map audible alarm only on 'ping' objects warn or down

Trying to modify 'An icon AA' into a custom file, to only alert on if a ICMP/PING Sensor has gone down, but im hitting walls as filter_type's etc dont work here.

<!--Status Icons: Status and Audible Alert (If Alarms > 0)-->

<div class="map_object map_icon <#sensor type="colorclassofstate" prefix="map_iconcolor_" id="<@objectid>">" id="<@itemid>" objectid="<@objectid>" subid="<@subid>" style="<#mapobject type="topleftcoordinates" subid="<@subid>" mode="<@editmode>">">
<#mapobject type="objectgrip" mode="<@editmode>">

  <span>
    <#objectstatus name="warnsens" id="<@objectid>" filter_type="ping">
    <#objectstatus name="downsens" id="<@objectid>" filter_type="ping">
  </span>
<div id="alarmsound"></div>
<script type="text/javascript">

  function playalarm() {
    if($('#audiblealarm').length <= 0) {
      $("#alarmsound").empty().append('<audio id="audiblealarm"><source src="/sounds/beep.ogg" type="audio/ogg" /><source src="/sounds/beep.mp3" type="audio/mpeg3" /></audio>');
    }
    var audiblealarm = document.getElementById("audiblealarm");
    audiblealarm.load();
    audiblealarm.play();
  };

  var errors1="<#objectstatus name="downsens" id="<@objectid>" show="textraw">";
  var errors2="<#objectstatus name="warnsens" id="<@objectid>" show="textraw">";
  var errors=errors1*1.0+errors2*1.0;

	if (errors > 0) {
		setTimeout(playalarm, 2000);
	}
