That's fine, they do a number of different designs (shapes) that model is the 1E this has 1 sounder (109 dB) that is fine for most situations.
The wiring couldn't be simpler on your panel you will have terminals marked A B C D S on the Bell Box you also have A B C D S you just connect like to like (A to A, B to B etc)
