Alarm siren help

Hi all
I need some help

I have just installed a ring alarm into a business premises and they have a very loud siren that is fitted to their exsisting alarm.
This is controlled by a 2 core trigger wire for activation.

Is there any way I can get this siren to sound when the alarm is triggered

I was thinking of some kind of alarm listener that switches on the two core trigger wire? Or maybe a zwave switch that triggers when the alarm is activated.
