4. most modern cars are very well sound insulated. If a car fails to respond to a particular siren then a change of tone may alert them. (if all else fails there is always a bull horn)
Sirens can be operated by both the driver and OiC) using either a foot switch. The road horn on the featured appliance also doubles as the siren changer.
3. It is not uncommon to have two appliances en route. varying the siren tone can warn of a second appliance (matching sirens can and have been mistaken for a single appliance causing vehicles to pull out into the path of the second appliance).
1. The 'wail' siren is allegedly more distinguishable on open roads and allows for better judgement of direction that the appliance is approaching from.
2. The 'yelp' siren is more suited to built up areas where the echo from buildings renders the 'direction sensing' obsolete.

sirens vary for several reasons...
1. The 'wail' siren is allegedly more distinguishable on open roads and allows for better judgement of direction that the appliance is approaching from.
2. The 'yelp' siren is more suited to built up areas where the echo from buildings renders the 'direction sensing' obsolete.
