Yesterday you told me to use accumulate instead of collect.
But i could not find the right way to use accumulate here.
Please see below my rules when condition [ collect function(Bold & Italic) ] and please tell me how can i use accumulate there. If possible change the conditional element to accumulate with appropriate changes.

when
	// "Sensor Data Idem Stream" is where Mule sends the Sensordata facts
    // for each Alarm / Sensordata combination that is identified via the vehicle id    
    $sd : SensorDataIdem ($vid : vehicleId) from entry-point "Sensor Data Idem Stream"
    						
	// Set a references for later on the initial facts 
    $av : AlarmVehicle(vehicleId == $vid)		
    		 							
	//The Condition to be added to get the active Alarms from the List of Alarms
	eval($av!=null && $av.getAlarms()!=null && $av.getAlarms().size()>0)
	
	<i><b>$alarms : ArrayList(size>0) from collect ( 
    		Alarm(  
    				(
    					(activation == AlarmConstants.ALWAYS_ACTIVE) 
    				||  (activation == AlarmConstants.ACTIVE_ONLY_ONTOUR && $sd.onTour == true)
    				||  (activation == AlarmConstants.ACTIVE_ONLY_NOT_ONTOUR && $sd.onTour == false)
    				||  (activation == AlarmConstants.ACTIVE_ONLY_ONMOVING && $sd.onMove == true)
    				||  (activation == AlarmConstants.ACTIVE_ON_TIME_WINDOW )
    				)
    				&&
    				( 	
    					(
    					(geofenceCustomer == 0) 
    				||  (geofenceCustomer == 1 && $sd.inCustomerGeoFence == true)
    				||  (geofenceCustomer == 2 && $sd.inCustomerGeoFence == false)
    					) 
    					&&  
    					(
    					(geofenceDepot == 0) 
    				||  (geofenceDepot == 1 && $sd.inDepotGeoFence == true)
    				||  (geofenceDepot == 2 && $sd.inDepotGeoFence == false)
    					) 
    				) 
    			) 
    		from $av.getAlarms() )</b></i>     						    						
	eval($alarms!=null)							  									  								   											
then
