Can be alarm turned on even if they are not chasing you?

Yes, with a script such as this
https://www.gta5-mods.com/scripts/pedestrian-riot

Thanks a lot man that fantastic

How do you get it to play what key do I press

@LavishMZ It's just a simple replacement of the siren in fort zancudo. A mod that allows you to play sound files from your game could work if you want to play the siren on demand.

i cant find the x64 in my mods folder pls help

What do you use to save/convert to a .awc file? I have been trying for a while to make my own alarm sound

@Xranovision - You haven't set up your mods folder correctly. Please copy these files (one at a time into your mods folder from the GTA 5 file folder: copy and paste):

*You must have at least 30 gigabytes of space on your Drive to do this.

update (this will take awhile)
x64
x64e (for audio)
x64i
x64w

Correction: I think the x64 file will come with the update file. So if it does appear you will know my memory 'aint so great lol
Love and Peace Sandy

I dont see SCRIPT.rpf in my sfx folder
