Seeing as you created it Venom im 120% sure it works lol.
Although i still think u should clean up your code a bit. using $did and $devent. Example:

If ($Devent == Sclick) { 
  If $did = 5 { 
  .splay stop
  .timersoonze 1 300 soplay $Read(Alarmsounds.txt, %alarmsound)
}

^ Just easyer for debugging
