Low Voltage

[grapefarmeral]

I recently purchased two items for a remodeling project. One is a servants call box and the other a buzzer. Both are from the UK. I know how to wire the units, what I don't know is the DC voltage required. The seller had no clue ( he thought maybe 4VDC) other than they both worked when removed from service. Is there a way of testing the units to figure the voltage or will buzzers work in a certain "range" of voltage.

Thanks
