As such, I haven't found direct information on where to place the fire alarm panel. However, there are some things to take into account.
Is there an annunciator for the firefighters as they enter the building? When they enter the building, the annunciator tells them where the fire is located.
Is it a "Total Evacuation" building? If all the horns and strobes in the entire building sound off so everyone in the building leaves in less than five minutes, then any fire protection of the fire alarm system only has to be good enough for everyone to leave.
Is it a "Staged Evacuation" building, or does it have "Defend in Place" sanctuaries in the building? If only some of the people are told to leave, and some people wait their turn to leave, then once a fire starts, any fire alarm equipment including panels and power supplies have to be protected from fire for two hours. That includes any fire alarm cabling or wires that go across fire zones.
In all cases, what needs to be done for protection is to install a smoke detector near any fire alarm control panel or fire alarm power supply. If a fire occurs inside the panel (I've seen the charred remains) or near the panel, a smoke detector within five feet or 1.5 meters is needed to sound the alarm before the panel burns up and can't sound the alarm for anyone in the building.
