Panic button for Galaxy Dimension

[Lamentable]

I've got a 48 zone Galaxy dimension and have a question in regard to panic button wiring.

I was thinking of getting one of these CQR panic buttons:

CQR PADP3_WH_M Push Button - CQR

SKU: PADP3/WH/M

cqr.co.uk

The spec. sheet says that is 24v and I am sure my system is 12v so would this be compatible?

If yes, is it just a cause of working out which resistance value I need to use for the tamper circuit?

Last question - can I connect two onto one zone?

Thanks in advance.

Yes
Galaxy is normally 1k /1k
And yes you can wire 2 on one zone
