Fire alarm one-way voice evacuation speakers in dwelling units

[Tainted]

I am designing a fire alarm system for a residential apartment building.

In NYC you are required to put speakers in dwelling units if the building is over 75ft tall.

What is a good rule of thumb for placement and spacing of speakers? Do you need one in every room?

What decibel levels do I need to achieve?

Generally, we place them above or adjacent to the entry door. There is usually no additional requirements for system connected notification in the dwelling units.

I wasn't talking about temporal 3 speakers. I was talking about voice evacuation speaker when FDNY picks up the mic by the building entrance and tells people to evacuate. (one way voice) Specifically this section of building code 907.5.2.2
