Does anyone know of a sounder suitable for mains use that won't deafen people within 10 yards. Ideally all I want is quiet beep beep and so on.

Dave Liquorice expressed precisely :
Mains powered ones tend to be robust and er, well, loud.
Why not find what you need in a low voltage version and feed it from a small wall wart? 12v output wall wart connected to a vehicle reversing alarm perhaps.
Other option is put silicone in the sounder housing of a 240v one. Not very elegant, but kills resonance.

A mains powered firebell and remove the gong?

Still very loud, I just want something you would be aware of rather than having your attention drawn to it. It's to wire across the "overheat" stat on a 38kW floor standing cast iron oil boiler. It trips fairly often due to being oversized for the load on it most of the time. But not oversize for the load that could be on it...
Even a vehicle reversing alarm would be a bit loud but is an interesting thought. It's that sort of beep beep beep I'm after, just a lot quieter.
Anything that does that will be basically low voltage so I'd guess you have more chance of finding a 12 volt one and use an external power supply.
