The ZTEP-103 siren by Zone Technologies is used by several police forces in the province of Quebec (Canada), including the Montreal Police Service (SPVM).
− This modification will replace the main GTA V police sirens with the air horn and main tones of the ZTEP-103.
− Features the choice of two versions: AH, WL, YP, and HL; or AH, WL, YP and HY.
− Due to game limitations, the yelp tone (YP) will be applied to all of the game’s emergency vehicles.
− To apply the ZTEP siren to any emergency vehicle, in the vehicles.meta file, set its <handlingId> flag to one matching the name of an emergency vehicle that uses the base siren and is similar in handling (ex. POLICE, POLICE2, POLICE3, PRANGER, POLICET…)
