Dual Siren

The dual siren (also called PowerCall) is a secondary siren that plays alongside the main siren. It's commonly used for intersections or high-priority responses where maximum audio presence is needed.

Behavior

  • The dual siren can only be activated when the main siren is already running.

  • It plays a separate sound from the PowerCallHandler configuration, layered on top of the main siren.

  • Turning off the main siren (or blue lights) automatically stops the dual siren.

  • The dual siren state is synchronized to all nearby players.

Configuration

In your vehicle config, set the Dualsirene property to a PowerCall preset name:

Dualsirene = 'MPcall',   -- A specific dual siren sound
Dualsirene = 'Pcall',    -- Another dual siren preset
Dualsirene = 'BPcall',   -- Fire department dual siren

If you omit Dualsirene from the config, the dual siren button will not appear in the UI.

Rumbler Siren

circle-info

New in V3 — The rumbler siren is a low-frequency siren designed to be felt through vehicles at intersections.

The rumbler replaces the current siren sound with a different, typically deeper tone from a separate siren preset.

Behavior

  • The rumbler can only be activated when the main siren is already running.

  • When activated, it replaces the main siren sound with the rumbler preset sound.

  • The rumbler uses the same tone number as the current siren — so if you're on tone 2, the rumbler plays tone 2 of the rumbler preset.

  • Toggling the rumbler off restores the original siren sound.

  • The rumbler state is synchronized to all nearby players.

hashtag
Configuration

In your vehicle config, set the Rumblesirene property to a siren preset name:

The value refers to a key in the SireneHandler table — the same format as the main siren presets. This means you can use any siren type as a rumbler, or create custom rumbler presets.

If you omit Rumblesirene or set it to 'geen', the rumbler button will not appear in the UI.

Combining Dual Siren & Rumbler

The dual siren and rumbler can be used simultaneously. When both are active:

  • The rumbler replaces the main siren sound

  • The dual siren plays on top as an additional layer

This gives maximum audio presence for critical situations.
