I do mostly residential work and have a question how you would wire three 120 volt buzzers around a warehouse controlled by a doorbell button for deliveries. I was thinking using a 120 volt contractor with 24 volt coil and transformer that would be controlled by the button outside by exterior man door .

Get a bell box and a 120v SS button that is mounted on a SS plate. I've tried the low voltage Bell's and they just weren't loud enough. I found the button made by "Edwards"

Depends what you use, same company (Edwards) has 24V bells over 100db, that's LOUD.
In a warehouse, you make them too loud, I think they become a bit of a hazard, if it's quiet and you're too close when they go off, you jump out of your shoes. Which is not good if you're on a ladder or driving a forklift.
I also like doorbell strobes or flasher, it doesn't have to be super bright, and if it's too bright that can be a hazard too, and there will be blind spots where you can't see them so the buzzer is necessary, but the flashers help.
The last ones I installed were up in the rafters 30'-40' off the floor one above the driver entrance and one in the back of the warehouse. They were loud but not crazy loud
When I was living in Kingston, NY we did alot of work for IBM. They had 5, maybe more, buildings that were very long built together. Most of their workers drove around in motorized carts. We unfortunately had to walk. They did give us small storage space where we could keep some materials so we didn't have to constantly go in and out to the vehicles. I hated working there- probably why I decided to get into residential work.
