This recording of a shopping centre security alarm was made in mono on a Sony ICD-BX112. The voice says (I think) "Security contact control".
If you use the sound, please comment about what you've done. I'd be excited to hear someone has found a use for it! 購物中心Alarm.wav 聲道:2 類型:wav alert、security、shopping-centre、alarm 警報、安全、購物中心的、報警 資料來源:freesound ( https://freesound.org )
