I would do floor-by-floor antenna pairs, and if each device going off should trigger the one on the next floor, I'd consider spacing them out so that you don't have one antenna pair feeding a strong signal to the next pair. If the only purpose of this is to relay the fire alarm signals, use high-gain, narrow beamwidth antennas pointed at the alarms, this will do wonders at overcoming the general noise on 2.4GHz I have too much radio experience to be happy trusting anything wireless for critical things, but where the alternative is no connectivity, it's better than nothing.
