There's a little bug in Security Alarm System program. When disarming, siren modules will not switched off.
To fix this, enter the program source and modify the very last lines of code by adding sirenModules.Off(); as shown below:
//Pause(1);
alarmModules.Off();
sirenModules.Off(); // <--- add the missing instruction here
}
Pause(1);
}
Update the program to make the change effective.
Cheers,
