I wouldn’t recommend it since this is an apartment building, which means the fire alarm system might have to wake everyone up if there is a fire in the middle of the night, and 3100Hz sucks at waking up people, which is why 520Hz low frequency sounders were invented, and while it’s very unlikely this building will get those (they aren’t required for retrofits or outside sleeping areas), the electromechanical tone will probably still be more effective at waking up people than 3100Hz. It’ll also prevent the main fire alarm system from being confused with a domestic smoke detector.
