The British Siren Simulator is a fun application designed for iPhone users who want to experience the sound of different sirens used in emergency vehicles. Developed by Rhys Hunter, this full version app falls under the lifestyle category. It is a simulator and should only be used for entertainment and not in a vehicle. The app does not contain any ads or pop-ups and is completely free to use.

The application comes equipped with two controllers: OPTI-LINK from Woodway Engineering and Genisys from Premier Hazard. The siren models available in the app are 295SLSA1 from Whelen, 7004 and 7109 from Premier Hazard, and Sterling from the Metropolitan Police. The siren button must be pressed and active to use the siren, and the steering wheel is used to activate the first tone. Pressing the steering wheel again switches between the different tones, and pressing twice deactivates the tone. Users can also use the horn when the siren mode is deactivated.

Please note that the light functions are currently not active. Also, ensure that your iPhone is not silenced and the volume is on to experience the full effect of the sirens.

Overall, the British Siren Simulator is a fun and entertaining app for iPhone users who want to experience the sound of different sirens used in emergency vehicles.
