I would guess it could quite easily pull 50 amps at 6 volts. Your best bet is probably a 6 volt starter relay if you can find one. I have a bunch of 12 volt Ford-type starter relays but no 6 volt units.
Bear in mind that starter relays are only meant for intermittent duty and will overheat if held on for too long. Since you're probably not going to be racing for miles to the fire with your siren on, this should be okay.
