Is it possible to use a different name brand NAC panel?

Hi just wondering if lets say i wanted to buy a siemens PAD3 and say use it on a Firelite panel, COULD i still trigger it as long as i provide it a 24v trip on the input of the nac panel from a facp nac output? thanks.

Yes, but it would be very helpful if you had a PAD 3 manual for wiring and dip switch setup. Any 24VDC would trigger it.
