Harrington Panel Question/ Fire alarm MR-201 Relays

[Birdem]

I have a question and help will be deeply appreciated. Im trying to use two mr-201 relays for fan restart and theater projection shut down. Im getting my 24 volts off the aux panel on the facp. how would I go about wiring up?

not sure what you are trying to do.
the mr-201 usually is added to a horn circuit when the horns sound the relay energizes.
