Is it possible to connect two doorbell switches to this one chime?

Hello,

I have bought a Legrand chime and two doorbell switches (i have two entrances to my home; one front door and one back door) and i want to have one bell switch outside next to each door and then have both bell switches work with the same chime. I would rather not have one chime for one switch only. But i am wondering if this will cause any trouble?

I have found the official technical documentation of my Legrand chime: https://assets.legrand.com/pim/NP-FT-GT/U4359B.pdf
(i have also attached the PDF file to this post for convenience)

There are two versions of this chime - with and without integrated transformer. I have the version without the transformer (since it was cheaper).

In the U4359B PDF, on page 2 under 41651, it is the chime that i have. Is it possible to connect 2 bell push switches to it? There is only AC 230V connected to it.

In the same U4359B PDF, on page 2 under 41652, this is the integrated transformer model. Is this one compatible with 2 bell switches? The chime terminals for the switch is DC.

But what if both bell switches are pushed at the same time? Won't it create a short circuit?

Edit: I have made a sketch to show the connections to illustrate my concern.

The problem you may have if you have a very remote doorbell push is volt drop. I did this once and there wasn't enough power going through the long cable to get the electromagnet to work properly. The answer was a second chime in series with double the voltage. It worked perfectly.
 
as the voltage to the bell/buzzer and bell push will be low voltage between perhaps 6-12v at the buzzer perhaps individual supply to front and backpush
the furthest away could be perhaps 10-15v as the volt drop would reduce to perhaps 7 to 12v dependant on length and wire chosen
with the nearest being say 9v giving perhaps 6-8v
now the sound will be different assuming voltage difference
now you could also have a separate control supply from the furthest away to a relay that will complete the circuit from the main bell push from the remote button but this will need a low powered separate supply but zero tone difference as the same voltage to buzzer from all sources

a further option, two separate circuits in any location with different bell/claxon/buzzer
and a further option mains plug in unit with 2 or 3 battery bell push --the modern choice at perhaps £15



i actually have a 2 bell 2 push set up
one on front door and one in the workshop at the back off the garden
bell in the house bell in the workshop
iff i am in the workshop when the door bells sounds i wait about 10 seconds then i push the bell push this gives a second double tone with a 8 second delay letting the person at the front door know i have reacted so am at home so coming
