Whelen Cencom siren actually fits QAS tbh.

Just a question for any of the emergency services buffs out there. Why do emergency vehicles, especially ambulance and police, cut their sirens way before the they get to the scene? I've noticed they often cut the siren just down the road from my place and then go past with just the flashing lights on.

This is a guess, but probably because they trust surrounding drivers to know that there’s an emergency nearby, and it’s obvious that they should steer clear (ie. the emergency is a warning enough, so the siren doesn’t need to be activated any longer.) As for the lights only, they don’t always stick the sirens on for the whole time for the following reasons 1. It’s late at night in a residential area, so lights only will reduce noise pollution. 2. The traffic is relatively light, so a visual warning is better. 3. They are stuck in a red light traffic jam. I have noticed this a bit my self, if an emergency vehicle is in a red light bottleneck, it’s unlikely to persuade traffic to move via the siren. Generally once the light goes green, the siren can be reactivated. All of these, especially the last one will vary between services and their EFAD training protocols, and this only a logical assumption, but this is my interpretation based on my own experiences.

Could just be a broken speaker or a way to run one siren only if they want
