Problem with Wireless Alarm Switch (WAL-220)

I use 2 function test with WAL-220 : 

- sent broadcast :

emberAfSendBroadcast(EMBER_RX_ON_WHEN_IDLE_BROADCAST_ADDRESS,
                    &sendAPSFrame,
                    EZSP_CONFIG_BROADCAST_ALARM_DATA_SIZE,
                    alarmData);

- send unicast :

emberAfSendUnicast(EMBER_OUTGOING_DIRECT, sender, &sendAPSFrame,
                    sizeof (alarmData) / sizeof (alarmData[0]),
                    alarmData);

WAL-220 cannot run warning sound.   

Any body help me ?
