Air Tank
Most of our coaches do have air horns. Does anybody know, what PSI they use and how large the air tank is?
thanks,
Ronald

Depending how they are plumbed, they could run off of the coach air system or aux air. Mine is converter installed and runs off the aux air side. 120 psi is usually the max. They will sound on less, but will usually sound weird when not over 90 psi. Doesn’t matter which air system they run off of, they work the same.

Ditto what Mark said, every bus I’ve had used aux air for the horns.

Here is the mother of air horns installed at Marathon factory. Set at 80 lbs psi supply source is Marathon Aux pancake air tank under drivers seat.

Train horns, I love it!!

When I pull the big knob for the train horn I can watch the aux air pressure gauge head down to zero. But it get’s everyone’s attention.

I was going to install a 12 volts fire engine siren on the bus, which I had bought on eBay.
Everyone thinks it sounds great and is loud. However, my wife does not like that idea thinking that it would confuse people, who may look for a real fire engine.
However, once she heard train horns, she was sold. … 🙂
Stay tuned.
